MX2 Reference Guide E-EQ-MX2RG-L-ARC

Chapter 1 Introduction and Specifications

Introduction

This reference guide is a technical supplement to the “MX2 User’s Guide”. It contains technical information about the MX2’s system configuration, disk drives, utilities, and DOS commands. Included in the appendices are connector configurations for the MX2 and the Single Dock and key maps for the MX2 keypads. For configuration parameters and barcodes for setting those parameters, please refer to the “Integrated Scanner Programming Guide for DOS Devices”, available on the LXE Manuals CD- ROM and the LXE ServicePass website. This manual is provided as a reference guide for system administrators, developers, and programmers who want to create end-user solutions for MX2 DOS portable computers. It is not intended for use by first-time MX2 users. There are two types of MX2 devices available. Both use hand-straps.

Pistol Grip Accessory (Standard with 48- No Pistol Grip Accessory (38-key keypad) key keypad, Optional with 38-key keypad) Figure 1-1 The MX2 Hand Held Computer, Rear Views

Note: Either the Pistol Grip or the Hand-strap are factory installed. Both cannot be connected to the same unit at the same time. The Pistol Grip handle is standard with the 48-key keypad. Note: Always store unused devices with a fully charged main battery pack installed. LXE recommends an in-use mobile device be frequently connected to an external power source to retain optimum power levels in the main battery pack and the backup battery. When the backup battery and main battery pack are dead, the mobile device reverts to it’s default values when a fully charged main battery pack is installed and the device is powered On again.

E-EQ-MX2RG-L-ARC MX2 Reference Guide 2 Introduction

In addition, the MX2 with Pistol Grip Accessory is available with either a 38-key or 48-key keypad. The MX2 without the Pistol Grip Accessory only uses the 38-key keypad. The 48-key keypad version is also available with a TN5250 overlay.

38-key keypad 48-key keypad Figure 1-2 The MX2 Hand Held Computer, Front Views

Note: All keypads are installed and configured by LXE.

LXE offers two basic configurations: • RF Configuration – a MX2 with a PCMCIA radio and antenna. The unit may be configured with or without an integrated laser scanner. • Batch Configuration – a MX2 without a PCMCIA radio and antenna. The unit may be configured with or without an integrated laser scanner. Both configurations can use the Single Dock without requiring adjustment. MX2’s running LXE’s Terminal Emulation programs require a PCMCIA radio, antenna and RF configuration files.

Note: Both configurations are available with either type of MX2.

Cleaning the Display / Scan Aperture

Keep fingers and rough or sharp objects away from the scan aperture and display. If the glass becomes soiled or smudged, clean only with a standard household cleaner such as Windex(R) without vinegar or use Isopropyl Alcohol. Do not use paper towels or harsh-chemical-based cleaning fluids since they may result in damage to the glass surface. Use a clean, damp, lint-free cloth. Do not scrub optical surfaces. If possible, clean only those areas which are soiled. Lint/particulates can be removed with clean, filtered canned air.

MX2 Reference Guide E-EQ-MX2RG-L-ARC

Chapter 2 Using Advanced Features

Introduction

This chapter provides information about advanced features of the MX2 computers. It does not cover basics, such as use of the keypad and display. For basic information about the MX2, see the “MX2 User’s Guide”.

Programming the Enter Keys (38-key Keypad)

Figure 2-1 Location of the Enter Keys

The MX2 with a 38-key Keypad allows reprogramming of one of the Enter keys. One Enter key may be reprogrammed from a list of available keys. There is no option for swapping the function of the Enter keys. However, if one key is reprogrammed, the other key automatically becomes the Enter key. This feature is not available with the 48-key Keypad.

To program an Enter key

First, hold down the [ALT] key then the [FN] key and press the desired [Enter] key to reprogram. The program-trigger icon should appear on the right in the display, indicating which Enter key is to be reprogrammed.

Left Enter Key Right Enter Key Figure 2-2 Program Trigger Icons

Select the key sequence to reprogram the Enter key. The following keys are valid selections: • Caps • Intl • Backspace • Tab • Enter

Note: All of these functions, with the exception of the Enter key, are the Fn shifted state of another key. When selecting the key, you do not need to enter Fn mode first. For example, to assign the left Enter key to Caps, press [ALT] then [Fn], then left [Enter], then [Ctrl]. The MX2 automatically translates the Ctrl keypress into the Caps key.

E-EQ-MX2RG-L-ARC MX2 Reference Guide 18 Key Combinations for International Characters (38-key Keypad)

Key Combinations for International Characters (38-key Keypad)

International Accent or Characters Letter Letter á, é, í, ó, ú, É ‘(apostrophe) a, e, i, o, u, E ç or Ç ‘(apostrophe) c or C à, è, ì, ò, ù ` a, e, i, o, u â, ê, î, ô, û ^ a, e, i, o, u ä, ë, ï, ö, ü, ÿ, Ä, Ö, Ü : a, e, I, o, u, y, A, O, U å, Å @ None ñ or Ñ ~ m, n, M, or N ß s s æ, Æ ! e or E ¿ ? None ¡ ! ! ¢, £, ¥ $ c, k, l, y

Enter international characters by using the following key sequence:

Fn-Alt accent letter where Fn-Alt is the key sequence to initiate the Intl key function, accent is a character from the “Accent or Letter” column, and letter is a character from the “Letter” column in the same row. After the international icon appears on the screen, the next key pressed displays an international character and the keypad reverts to normal mode.

International Characters and LXE Terminal Emulations The international characters shown above are supported in DOS mode only. LXE’s terminal emulation applications (ANSI Plus, TN3270/-E and TN5250) do not support these particular international characters. Use the terminal emulation application configuration utilities to create international characters for use when running terminal emulation applications on the MX2.

MX2 Reference Guide E-EQ-MX2RG-L-ARC Resetting the MX2 19

Resetting the MX2

One of the critical features of any portable data-collection device is its ability to protect against accidental data loss. In the event a MX2 becomes “locked up” or otherwise in a state in which data can no longer be processed, you can use any of four methods to reset the unit. This chapter describes these methods.

Warm Boot The warm boot is one of two software methods for resetting a MX2. It is analogous to the CTL- ALT-DEL key sequence for rebooting IBM-compatible PCs, and the same key sequence is used to force a warm boot on a MX2. This method of resetting a unit should be used first to attempt to bring it back to a usable state.

Note: You do not need to press the FN key to activate the DEL function of the BkSp key. Since a warm boot can be attempted only from a unit that has been turned on, certain assumptions are made. For example, the rigorous hardware tests that are performed as part of the cold boot sequence are not all necessary. This means the unit restarts faster with a warm boot than with a cold boot. During a warm boot, data written to the RAM drive (D), the flash drive (C), or an ATA flash card will remain intact. However, if an application is running on a unit before a warm boot, its state cannot be restored.

Note: If you do not want end users to be able to reset the unit, scan the “Enable CTL-ALT-DEL Reboot Off” barcode in the “Integrated Scanner Programming Guide for DOS Devices”, available on the LXE Manuals CD-ROM.

Cold Boot The second software method for resetting a MX2 is the cold boot. A cold boot should be used only if a warm boot is unsuccessful. Performing a cold boot is analogous to pressing the reset button on a PC or to turning the PC’s power off and then back on. To perform a cold boot on a MX2, first turn it off. Then press [ALT] + [FN] + [Power], holding the first two keys down while pressing the third. Release all three keys simultaneously, and the unit will reset. Simply removing and inserting the battery pack will not force a cold boot, because the backup battery can provide minimal power to sustain the MX2’s operating state. The exception to this is when the backup battery is drained of all power, a condition that you should not let happen. When a cold boot is performed, all transient data is lost, along with the state of any application that was running on the unit. Data written to the RAM drive (D), the flash drive (C), or an ATA flash card will remain intact. If a cold boot happens because of a dead backup battery, data written to a RAM drive may not be maintained. A cold boot begins with a retesting of the hardware and then follows with the DOS boot sequence. The unit reboots DOS under the same conditions you would expect from a desktop PC: Device drivers included in the CONFIG.SYS file and applications included in the AUTOEXEC.BAT file are automatically loaded as part of the boot process; any other programs that were loaded before the cold boot will not be reloaded automatically.

E-EQ-MX2RG-L-ARC MX2 Reference Guide 20 Resetting the MX2

Safe Boot During the DOS boot sequence, control is passed sequentially to the CONFIG.SYS files on drives A, B, and C. A similar process is followed for the AUTOEXEC.BAT files on each drive. It is possible for a driver or application loading from the CONFIG.SYS or AUTOEXEC.BAT file on drive C to hang the system. A cold or warm boot of the unit will not directly correct the problem, because the troublesome program will be started again as part of the boot sequence. What is required is a method by which the CONFIG.SYS or AUTOEXEC.BAT file on drive C and the loading of the CFGDEV.SYS and DECODE.SYS drivers can be taken out of the normal boot sequence. DOS can help some, with the CTL-C and the F8 escape sequences. The MX2 provides an alternative method that is less accessible to the end user. To bypass the CONFIG.SYS and AUTOEXEC.BAT files on drive C, reboot the unit (with either a cold or warm boot), and when the message “Wait…” appears on the display, immediately press the [ESC] and [Space] keys at the same time. This causes alternative CONFIG.SYS and AUTOEXEC.BAT processing to take place on drives A and B without chaining into the files on drive C. The unit indicates safe-boot mode by emitting a low tone followed by a higher-pitched tone. The flash drive (C) and the RAM drive (D) will be preserved, and the boot sequence will place the unit at the C:\> prompt.

Note: If you do not hear the two tones indicating the safe-boot sequence, you probably did not press the ESC and Space keys quickly enough. Reboot the MX2 and press the two keys simultaneously as soon as you see the “Wait…” message on the display.

Hardware Reset In the extremely rare situation where none of the rebooting methods is successful, you can use a reset mechanism that is located below the keypad matrix directly below the Lamp key. By inserting a paper clip or other narrow device and pressing gently, the unit will perform a hardware activated cold boot. Only use the same amount of pressure used to press a normal key. Do not use a sharp instrument. If the keypad rubber matrix is punctured, the industrial specifications of the MX2 could be compromised.

Note: Attempt at least two cold boots before going into Hardware reset.

Figure 2-3 Location of the Hardware Reset Mechanism

Upon reset, you will need to set the date and time in the MX2. These DOS programs may run automatically after a Hardware Reset.

MX2 Reference Guide E-EQ-MX2RG-L-ARC Using PC Cards 21

Using PC Cards

Note: The PC card slot of the MX2 is not user accessible, but functions in the same manner as the LXE 2325 for software installation, use and general features. Please refer to the "LXE 2325 Reference Guide” for PC card information. The MX2 has a slot for plugging in PC cards, and each unit is factory-equipped with Phoenix CARD Manager Plus PC card drivers. PC cards provide such features as network connectivity, modem connectivity, and wireless capability. Their primary purpose in the MX2 is to provide additional memory storage by functioning as a disk drive. The MX2 holds one PC card at a time. If the MX2 has a radio card installed, the radio card will need to be removed before a different PC card can be inserted.

The IR Serial Port

Figure 2-4 The IR Port on Bottom of Unit

The serial port is a half duplex IR (Infrared) port. Through software commands, the port may be set up for IR or a modified RS-232 serial communication. In general, the IR mode is used when communicating to other IR devices (printers, computers, etc.) and the modified RS-232 mode is used to communicate with the dock for host communications. In IR mode, all physical communications meet the IrDA physical layer specification. In the modified RS-232 serial mode, the IR port is used to transmit RS-232 level data out the IR port. With the MX2 in the dock, the keypad facing the front of dock, the left-most pad is the RS-232 input (RXD) into the MX2 while it is in the dock.

Note: The MX2 does not propagate the RS-232 hardware signals such as RTS, CTS, DTR, DSR, RI and DCD. When transferring files using the IR port, flow control must be the same on both sides of the transmission (specifically, with Zmodem: both sender and receiver must use Xon/Xoff).

E-EQ-MX2RG-L-ARC MX2 Reference Guide 22 Laser Scanner

Laser Scanner

Figure 2-5 Scanner Aperture Location

The Standard Range Scanner aperture is located at the back at the top of the MX2. Barcode scanning is initiated when: • The user presses the Scan button on an MX2 with 38-key keypad. This version of the MX2 has one scan button – a large key in the middle of the keyboard labeled Scan. This key cannot be reprogrammed. • The user presses the Scan trigger on the handle. The handle is standard with the 48- key keypad MX2. Since this model has no Scan button, this is the only way to initiate a scan on the MX2 with 48-key keypad. MX2’s with the 38-key keypad may have an optional handle. In this case, either the Scan button or trigger can be used.

Scan Button Location (38-Key Keypad) Scan Trigger on Handle (Standard with 48- Key Keypad, Optional with 38-Key Keypad)

Figure 2-6 Scan Button and Scan Trigger

The only option for scanning with the MX2 is with the internal laser. Due to sealing and environmental issues, no external port is available for external tethered scanners. When the MX2 does not have an installed scanner, although the scanner aperture is present, pressing the Scan button or trigger has no effect. To use the laser, aim the top of the unit at a barcode and press the Scan button. A red LED directly below the LCD display indicates when the scanner is active. The LED switches to green when a scan is successful.

MX2 Reference Guide E-EQ-MX2RG-L-ARC The Disk Drives 25

The Disk Drives

The MX2 contains four logical disk drives that provide storage for system files, applications, and data. Drive A is a read-only drive. Its contents cannot be changed. Drive B is a read-only drive used to store system utilities and to initialize the boot process. Its contents cannot be changed. Drive C is a flash disk drive that allows full read and write access. This drive contains DOS command files, PC card drivers, utilities, and executable files and associated files for applications. It may also contain additional CONFIG.SYS and AUTOEXEC.BAT files to configure your MX2 to run applications. Drive D is a RAM disk drive. The RAM disk is used primarily for data storage. Programs that need to be loaded into memory and then quickly removed from memory can also be placed here. Drive D can also be used for scratch disk space or temporary files.

Note: As with any RAM drive, data on drive D can be lost if the MX2 has a power failure caused by low batteries or a system reset. For truly secure data collection, store your data on drive C or on an ATA flash card.

Additional Drives Drive E exists only if your unit has been configured to use PC ATA flash cards. The PC card looks like a hard disk drive to the operating system. You can use drive E for safe and permanent storage of data. Alternately, drive E could be a peer-to-peer or client-server network drive that is accessed through a wireless access point or Ethernet network card link. Your unit may have other additional logical drives. These might be RAM drives, ATA flash cards, or network drives accessed via wireless access points.

E-EQ-MX2RG-L-ARC MX2 Reference Guide 26 Configuring the MX2

Configuring the MX2

If your unit is not already configured for use when you get it, please refer to “Radio PC Card Configuration”, later in this chapter and also to Chapter 3, “Software Configuration”. You can also scan barcodes with the MX2 to change MX2 configuration settings. For more information, please refer to the “Integrated Scanner Programming Guide for DOS Devices”, available on the LXE Manuals CD-ROM.

Troubleshooting - Enable I 2 of 5

Problem The MX2 configuration does not retain “Enable I 2 of 5” after power down. Note that this is an isolated incident and that the default MX2 with scanner configuration automatically enables Code 39, I 2 of 5, Codabar/Ames, Code 128, UPC-A and EAN/JAN.

Solution Create a file containing the actual character string of the barcode used to set that particular parameter. The character strings are printed under the barcode in the “Integrated Scanner Programming Guide for DOS Devices”, available on the LXE Manuals CD-ROM – do not add the asterisks to the character string. Any number of setup strings can be used, one per line in the file used. After the file is created, copy the contents to the device PARAMS when the AUTOEXEC.BAT file is loaded. For example, the setup string to enable I 2 of 5 is $+$-151EE. 1. Create an ASCII file – CUSTPARM.TXT – that contains the following line: $+$-151EE 2. Place the following line in the AUTOEXEC.BAT file and the command will be run each time the AUTOEXEC.BAT file is run: COPY CUSTPARM.TXT PARAMS

Transferring Files

To transfer data or program files, connect your MX2 to the host computer with any of the following accessories: • Serial cable • Single Dock Your software application may have simple file-transfer options, or you can use the REMDISK and REMSERV utilities. For more information on REMSERV and REMDISK, please refer to Chapter 4, “Commands”.

MX2 Reference Guide E-EQ-MX2RG-L-ARC Advanced Power Management 27

Advanced Power Management

The MX2 uses advanced power management (APM) to provide the longest battery life. Control of the APM features is provided in the PM.COM utility on drive B of each MX2. This section provides additional information for getting the most power life out of an MX2 RF unit using the RangeLAN2 wireless LAN PC card.

Batteries For RF units, LXE recommends the use of fully charged batteries. In general, an MX2 with an RF card should be able to get through a normal 8-hour shift before the batteries need to be replaced or recharged.

Doze Mode After 8 seconds without a keypress, scanner input, or other system activity, the MX2 goes into a power-saving state known as doze mode. To maximize battery life, especially in an RF environment, try to avoid accidental or unnecessary pressing of the keypad keys.

Auto-Off Timer After a predetermined time without any system activity, the unit automatically shuts off. The default auto-off timeout is 5 minutes. To maximize battery life, you can set the timeout to a much shorter period. The “Integrated Scanner Programming Guide for DOS Devices”, available on the LXE Manuals CD-ROM, includes bar codes that provide auto-off settings as low as 20 seconds. You can also use the PM.COM utility to set the auto-off timer.

Backlight Use of the display backlight severely affects battery life in the MX2. For RF applications, do not use the backlight unless it is absolutely necessary. If you do need to use it, you can change the display’s auto-off timer to a setting lower than the default (15 seconds). The “Integrated Scanner Programming Guide for DOS Devices”, available on the LXE Manuals CD-ROM, includes bar codes that provide settings as low as 2 seconds for the backlight auto-off timer. You can also use the PM.COM utility to set the timeout.

E-EQ-MX2RG-L-ARC MX2 Reference Guide 28 Advanced Power Management

Power Management at the Radio Card To conserve battery life, the radio card has an inactivity sleep mode. The sleep mode is automatically engaged when a certain period of time has elapsed since the computer has sent or received data over the network. Once the card is asleep, it can be awoken by an access point attempting to send data to it. The time before sleeping is calculated by adding the Inactivity_min and Inactivity_sec parameter settings.

Note: Do not set an inactivity timeout on an RF MX2 being used as a master station. If the unit goes to sleep, you will lose all communication with your network. The access point buffers packets that are to be sent to the MX2s. A dozing radio card will receive a sync message and wake-up list from the Access Point every 400 ms. The AP adds a media access control (MAC) address to the wake-up list each time a send attempt fails. (The access point buffers the packet and adds the MAC address of the MX2 to its wake-up list.) If an MX2 detects that it is on the wake-up list, the radio card exits doze mode and enters receive mode. Once the radio card wakes up to receive the packet, it stays awake for all future sends until the inactivity timeout expires. This is why it is important to have the inactivity timeout as low as possible. The advantages of a higher timeout value is that the radio card will remain in Receive mode for longer periods of time; network throughput may be better because the unit will not have the delay of coming in and out of doze mode or of waiting for the wake-up list to see if there are any packets. Generally, in the types of environments that the radio card will be used in, the user should strive for maximum power management. Most MX2 RF applications will not be expecting asynchronous network traffic, and it is doubtful that throughput differences due to power management will be noticeable with these types of applications. Always set the Inactivity_min parameter to 0, and set the Inactivity_sec parameter as low as possible (preferably to 1). Never set Inactivity_sec to 0, as that turns off the power management completely, and the card will always stay in receive mode.

MX2 Reference Guide E-EQ-MX2RG-L-ARC Radio PC Card Configuration 29

Radio PC Card Configuration

Note: LXE will pre-install radio cards and drivers on MX2 RF units before delivery. These instructions are included for those users who may need to reinstall radio drivers and reconfigure radio parameters. After installing the radio card, you must configure the MX2 to use the card. Please refer to the appropriate section for your radio card in the remainder of this section.

Note: Symbol FHSS radios are obsolete (6/2005).

Introduction

Note: The information and programs in this section only pertain to LXE’s 2.4GHz system radios. They do not work with LXE’s 900MHz system radios.

Change the radio parameters by editing the NET.CFG file in the PCTCP directory. This can be done with any ASCII text editor or NED. The NET.CFG file is the configuration file used by the radio card’s ODI driver. The NET.CFG file determines the wireless network name, the workstation name and other information regarding the wireless system. 2.4GHz radio parameters cannot be changed using LXE’s terminal emulation (TE) configuration utilities. The Sockets software package provides an interface to all of the TCP/IP parameters. Parameter configuration is performed by editing the file SOCKET.CFG.

E-EQ-MX2RG-L-ARC MX2 Reference Guide 30 Radio PC Card Configuration

NET.CFG Parameters

Lucent Parameters The following is a list of parameters that can be modified in the NET.CFG file for computers with Lucent 2.4GHz radios. For additional information about the parameters in this file see the WVLAN43.CFG file located in the PCTCP directory. To set the TCP/IP parameters see the SOCKET.CFG file documentation.

Link Support Parameter used to define resources for the LSL.COM file. Any modifications may cause resource conflicts.

Protocol Instructs TCP/IP stack to bind to radio driver.

WaveLAN_Network_Name Identifies the WaveLAN network the station will connect to. Valid: 0 to 32 string of printable uppercase characters. Default: ANY

Note: Setting this value to ANY will enable the station to connect to any IEEE 802.11 network. Note: The string for WaveLAN_Network_Name is case-sensitive. The WaveLAN DOS ODI driver requires the use of only UPPERCASE characters. If you have configured the Access Points with lower-case names you will need to change your Access Point WaveLAN_Network_Name parameter to UPPERCASE characters for proper operation. Or, place double quotes around the WaveLAN_Network_Name to allow proper operation with upper and lower case letters e.g. "NameofUnit".

Station_Name Identifies the stations on the network. This parameter is used when performing diagnostic tests. Valid: 0 to 32 string of printable characters. Default: station_name

AP_Distance Controls the roaming sensitivity of your computer. This parameter must be set according to the settings of the WavePOINT-II access points. Valid: 1=Low 2=Medium 3=High Default: 1

MX2 Reference Guide E-EQ-MX2RG-L-ARC Radio PC Card Configuration 31

Microwave_Robustness This option should only be used when troubleshooting slow performance of the network that could be related to in-band interference from microwave ovens. Use this option when experiencing recurrent “bursts” of in-band interference exhibited by specific units where the unit (or the access point) is close to a microwave oven or a microwave oven is located in the signal path between the unit and the access point. The radio will try to retransmit the “lost messages”. When retransmission fails again, the radio in Auto Transmit Rate Select Mechanism mode will attempt to retransmit the message again at a lower data speed. (See Transmit_Rate) Selecting “Y” will enable fragmentation of data frames when the automatic transmit rate selection switches to a lower transmit rate. Fragmentation will avoid increased vulnerability due to longer frame lengths of transmissions at lower data speeds. Valid: Y=Yes, N=No Default: N

Transmit_Rate Controls the data rate the WaveLAN card will use. Supported rates depend on the card. If the card does not support the selected rate, the default value of 3 is selected automatically. Valid: 1=Fixed Low 2=Fixed Standard 3=Auto Rate Select (High) 4=Fixed Medium 5=Fixed High 6=Auto Rate Select (Standard) 7=Auto Rate Select (Medium) Default: 3

Medium_Reservation Enables RTS/CTS communications. Sets the frame length threshold that determines when the station should start using RTS/CTS. Valid: 0-2347 Default: 2347

Note: The use of Medium Reservation is recommended in network environments where the density of the WaveLAN stations and WavePOINT-II access points is very low, and where there is poor network performance due to excessive frame collisions at the WavePOINT-II access points.

Card_Power_Management Configures the power management used by the station in an ESS. The recommended mode is Enhanced Power Management (EPM) for hand held computers. In this mode, the station switches between Power Save Mode (PSM) and Continuous Active Mode (CAM), based on activity. Any frame transfer switches the station to CAM. Inactivity for 100ms switches the station to PSM. For hand held computers, the default is EPM. Valid: 0=CAM (No power savings) 1=EPM 2=PSM (Maximum power savings) Default: 1

E-EQ-MX2RG-L-ARC MX2 Reference Guide 32 Radio PC Card Configuration

Maximum_Sleep_Duration Configures the maximum amount of time the radio will stay in Sleep mode. Valid: 1-65535 Default: 100 (10 seconds)

Receive_All_Multicasts Configures whether this station will receive Multicast packets. Valid: Y=Yes or N=No Default: N

Enable_Encryption Configures whether this station will receive/send encrypted data traffic. When “Y” is chosen, the unit will be able to receive both non-encrypted data and messages encrypted with one of the listed WEP encryption key values (see Transmit_Key_ID). If encryption is enabled (Y) while the card does not support WEP, an error is reported. Valid: Y=Yes or N=No Default: N

Transmit_Key_ID If you enable WEP encryption, you can select one key for wireless data transmissions from the list of WEP Encryption Key Values. Key1 abcde Key2 0x123456789a Key3 abcdefghijkl2 Key4 0x112233445566778899AABBCCDD Valid: 1-4 Default: 1 Format: Transmit_Key_ID 1

SOCKETS TCP/IP Stack

Introduction SOCKET.CFG sets the options for SOCKETP.EXE. The section XXX.XXX.XXX.XXX is for this machines IP. The net mask is specified as part of the IP address. In the IP address command an optional /net_bits can be used to indicate the number of bits in the network ID.

Net Bits Net Mask Class IP address range 8 255.0.0.0 A 0.x.x.x to 127.x.x.x 16 255.255.0.0 B 128.x.x.x to 191.x.x.x 24 255.255.255.0 C 192.x.x.x or higher

The network can be subdivided by two for every net bit added.

Net Net Net Net Bits Mask Bits Mask 1 128 5 248 2 192 6 252 3 224 7 254 4 240 8 255 Bootp BOOTP is a UDP/IP based protocol that provides a means to assign an IP address to a booting host dynamically and without user supervision. BOOTP can also supply the net mask, host name, and address of a domain name server. One obvious advantage of this procedure is the centralized management of network addresses, which eliminates the need for per-host unique configuration files. Sockets implements the BOOTP client whenever it is started with no (or the 0.0.0.0) IP address supplied.

DHCP DHCP is a UDP/IP based protocol that provides a means to assign the IP address dynamically to a booting host and without user supervision. It can also supply the net mask, host name, address of a domain name server, and other parameters. An advantage of this procedure is the centralized management of network addresses, which eliminates the need for per-host unique configuration files. Sockets implements the DHCP client whenever it is started with the 0.0.0.1 IP address supplied. All LAN interfaces specified when this IP address is in use will attempt to use DHCP to resolve the IP address, the subnet mask, hostname, default router and DNS server(s).

SOCKET.CFG Parameters domain If a host name is not a decimal (dotted) address and it is not found in the HOSTS file and at least one Domain Name Server has been defined, an attempt is made to obtain the address from the defined DNS server(s). The number of times any server is polled (retries), in addition to the time to wait for a response, can also be specified. A suffix may be specified and is attached to all names not containing any dots. All of the following sub-commands can be issued without the optional parameters to obtain information on the current status.

Syntax domain server [host_name] domain retry [retry_count] domain time [wait_time] domain suffix [domain] domain server adds a DNS address or lists the current servers if host_name not specified. domain retry specifies the retry count for polling each server. domain retry lists the retry count if retry_count not specified. domain time specifies or lists the time (milliseconds) to wait for a response before attempting retry. domain time lists the time (milliseconds) to wait if wait_time not specified. domain suffix specifies the domain suffix to add to all simple names; names that contains no dots. domain suffix lists the domain suffix if domain is not specified.

Example domain retry 3 domain server 196.2.1.1 domain suffix myorg.co.za domain time 2000 iface iface is a synonym for the interface command. interface interface informs Sockets of the hardware or software communications interface(s) to be used at the network interface level. At least one network interface is required, and two or more are used in gateway (router) applications. The class or mode of each interface defines the encapsulation used for packaging the data frame into the transport frame. Some types of interface support only one class. When using more than one interface, Sockets assigns the previous given IP address in the .CFG file to this interface and uses its net mask to add a route to that net through this interface. Using the same IP address would result in multiple routes to the same network. The default route is set on the first interface with an IP address with a zero net mask (for example, IP address 100.100.100.100/0). Each interface statement uses the IP address from the last supplied IP address statement.

Parameters Type Type defines the type of hardware or software interface. interface supports the following software interfaces.

Interface Description

Asy Standard PC asynchronous interface (RS232 port)

Pdr packet driver interface name name defines the name by which the interface is known on the local host. name is a symbolic name known only to the local host on which it is used. name may be arbitrarily assigned. Each interface command on the same host must have a unique name assigned. This name is used by commands such as route, trace, param, and so on. class class specifies how IP datagrams are to be encapsulated in the link level protocol of the interface. Some interfaces offer a choice between classes while others use a fixed class. The following classes are available and are listed with their associated types.

Type Class (defined in the following list) Pdr dix, ieee, token, driver, slip Asy raw, slip, cslip, ppp

Class Description Dix The DEC/Intel/Xerox Ethernet interface also known as Blue Book Ethernet or Ethernet II. Token IBM Token Ring. Source routing is supported for multiple rings. Ieee IEEE: 802.3 Ethernet with SNAP headers. Driver Use the default class for the packet driver. Slip Serial Link Internet Protocol (SLIP) for point-to-point asynchronous links. This mode is compatible with UNIX SLIP. Cslip Compressed Serial Link Internet Protocol (SLIP) for faster reaction over point-to-point synchronous links. Ppp Point-to-point protocol over asynchronous links.

E-EQ-MX2RG-L-ARC MX2 Reference Guide 46 Radio PC Card Configuration

mtu mtu specifies the Maximum Transmission Unit size, in bytes. Datagrams larger than this limit are fragmented into smaller pieces at the IP layer. The maximum value of mtu for the various interfaces is: Ethernet - 1500 For serial links a standard value for mtu is 576. (576 is the maximum according to specifications, but may be increased on reliable connections as long as both sides use the same value.) numbuf numbuf specifies how many incoming datagrams may be queued on the receive queue at one time. If this limit is exceeded, further received datagrams are discarded. This mechanism is used to prevent fast interfaces from filling up memory when data cannot be handled fast enough. buflim buflim specifies the maximum number of outgoing datagrams or packets to queue before starting to discard datagrams. This mechanism is used to prevent the memory from filling up when a serial link goes down. bufsize bufsize specifies the size of the ring buffer in bytes to be allocated to the receiver in raw mode. intvec intvec specifies the software interrupt number (vector) in hexadecimal to use for resident packet drivers. ioaddr ioaddr is the I/O base address in hexadecimal of a serial port or the hardware controller and must correspond with the jumper or switch settings used during the setup of the controller board. The standard values for serial ports are: COM1 03F8h COM2 02F8h COM3 03E8h COM4 02E8h iovec iovec is the hardware interrupt vector used by the serial port or controller and must correspond with the jumper or switch settings used during setup of the controller. The standard values for serial ports are: COM1 4 COM2 3 COM3 4 COM4 3 irq irq is the hardware interrupt vector used by the network interface controller. This is only used for faster response in Sockets. modemfile A file containing the modem commands and scripts. speed speed specifies the transmission speed for serial interface devices (baud rate). Before using a serial connection you have to set flow control with the param command.

Syntax ip address [hostid [/net_bits] ] ip status ip ttl [number] ip address sets the IP host address of the next interface to be defined. A route is automatically added to each interface for the default or specified net mask for its address. To make an automatic route the default, specify the net bits as zero. When specified without the optional parameters, ip address displays the current value(s) of the local host IP address(es). To assign different IP addresses to different interfaces on the same host, an ip address statement must precede each interface definition. The last IP address given is used in case of missing ip address statements. ip status displays Internet Protocol (IP) statistics, such as total packet counts and error counters of various types. It also displays statistics on the Internet Control Message Protocol (ICMP). This includes the number of ICMP messages of each type sent or received. ip ttl sets the default time-to-live value which is placed in each outgoing IP datagram. The ttl value limits the number of gateway hops the datagram is allowed to take in order to kill datagrams that got stuck in loops.

Parameters hostid hostid specifies the IP host address to assign to the next interface to be defined. This may be a symbolic name from the HOSTS file, or a dotted decimal address. /net_bits A net mask can be specified for the host. In the ip address command an optional /net_bits can be used to indicate the number of bits in the network ID. The net mask is used to determine whether an incoming datagram is a broadcast and also for sending UDP broadcasts. Net masks are more easily represented in binary or hexadecimal format. For example, the IP address 128.1.1.5/24 corresponds to a net mask of 255.255.255.0 (FFFFFF00h), 25 bits to 255.255.255.128 (FFFFFF80h) and 26 bits to 255.255.255.192 (FFF FFC0h). The default net mask used corresponds to the class of address used if not explicitly specified.

Net Bits Net Mask Class IP address range 8 255.0.0.0 A 0.x.x.x to 127.x.x.x 16 255.255.0.0 B 128.x.x.x to 191.x.x.x 24 255.255.255.0 C and higher 192.x.x.x or higher

E-EQ-MX2RG-L-ARC MX2 Reference Guide 48 Radio PC Card Configuration

If you want to subdivide your network, you can divide it by two for every net bit added. The following table provides information on converting between net bits and net mask. The number of net bits to add when changing a 0 in the net mask to:

Net Bits Net Mask Net Bits Net Mask 1 128 5 248 2 192 6 252 3 224 7 254 4 240 8 255

number When number is omitted, ip ttl displays the current value of the time to live parameter. param param invokes a device-specific control routine. When executed without parameters, param displays defined interface names and device-specific flags. param operates differently for each interface type and even interface mode. In many cases it is used to interrogate the status of an interface. The ifstat and param commands perform similar and, in some cases, exactly the same function.

Syntax param ifname [arg1...argn]

Parameters ifname ifname defines the name used in the interface command for the device to be controlled. arg1...argn These parameters depend on the type of interface in use.

Example To display current serial link settings and restart the statistics on it, use: param sl0 clear

param, Alternative Routing Control Sub-commands The Alternative Routing Control Sub-commands set up and check the Sockets alternative route mechanism. More than one route can be specified to a target host or network. The first route which has an associated interface in the up state is used. An interface is in the up state when it is defined by the interface command. It enters the query state when it does not receive valid input within a specified up-time period after sending data expecting a response. At this stage three (catering for links with a high data loss) ICMP echo requests (ping) are sent to a query IP address. It enters the down state by a Sockets command or when it does not receive valid input within the specified up-time period after entering the query state. If an up-time has never been specified or a value of 0 is specified, the interface will stay in the up state whether valid input is received or not.

MX2 Reference Guide E-EQ-MX2RG-L-ARC Radio PC Card Configuration 49

An interface enters the up state by a Sockets command or when valid input is received on that interface when in the down or query states. An ICMP echo request is sent on an interface in the down state every down-time period. If a down-time has never been specified or a value of 0 is specified, the ICMP echo request will not be sent. Up-time and down-time is specified in seconds.

Syntax param ifname [ uptime | downtime ] time param ifname query hostname Example Alternative Routing Two X.25 interfaces are used to get to the target network 192.6.1.0. The first interface, named if0 should preferably be used, but if it stops receiving for a period of 20 seconds, it should try to ping 192.6.1.2 and if no response is received within another 20 seconds, if1 should take over, but if0 should be tried every five seconds. Interface if1 should disconnect after 80 seconds of no traffic. The SOCKET.CFG file should contain the following: interface x25 if0 ...... param if0 uptime 20 param if0 downtime 5 param if0 query 192.6.1.2 interface x25 if1 ...... param if1 uptime 80 param if1 downtime 5 param if1 query 192.6.1.2 route add 192.6.1.0 if0 route add 192.6.1.0 if1 In the case of both if0 and if1 failing, both are tried every five seconds until one comes up. The return paths should also be maintained in a similar way with Sockets or by using RIP.

param, RIP Advertising Sub-command for Interfaces When the rip advertise command has been used, this param sub-command makes allowance to disable and re-enable RIP advertising on a specific interface.

Syntax param ifname [ ripadv | noripadv ]

Examples param if0 noripadv param if1 ripadv route route creates an entry in the IP routing table for Sockets to determine where to send data. The Alternative Routing mechanism allows more than one route to be specified to a particular host or network. Failure of one route causes an automatic switch to the next route. Refer also to the ip address command for specifying the net mask, because a route is automatically added to each interface for the default or specified net mask for that address. When multiple routes are defined to the same address, Sockets uses the route with the network size (largest number of bits in the net mask).

E-EQ-MX2RG-L-ARC MX2 Reference Guide 50 Radio PC Card Configuration

Syntax (general) route [ add | drop destination ifname [gateid |none [ metric [proxy] [private] [static] ] ] ]

Syntax (specific) route add [ hostid | netid ] ifname [gateid] route add [ hostid | netid[/mask] ] ifname [gateid] route add default ifname route drop [ hostid | netid ] route drop [ hostid | netid[/mask] ] route drop default

Parameters add or drop Sub-command to add or drop (remove) a route from the routing table. default All transmissions to IP addresses not otherwise defined in routing commands are sent via the network interface specified by ifname. hostid hostid is the IP address of a destination remote host to which data must be sent, or a remote host which must be removed from the routing table (dropped). netid netid is the IP address of a destination network to which data must be sent. Any host with this IP network address is able to receive the data. Whether a particular host will use the data depends on the host portion of the specific IP address in the IP header. mask mask specifies the number of bits in the network portion of the address if sub-netting is used. If not used, the network portion of the address is determined according to the class (A, B or C) of the address. ifname ifname defines the name used in the interface command for the immediate network on which the data for the designated host must be sent. This is the network level interface to be used by the local host to reach the remote host. gateid gateid parameter specifies the IP address of a host, on the same physical network as the local host, which is used as a gateway or router to a different network. The gateway or router host specified in gateid must be directly reachable on the same physical network as the local host defining this gateway. In other words, this must be the nearest gateway to this local host. metric When using RIP or Proxy ARP a value from 0 to 16 for metric must be specified indicating the distance or cost of that route. A metric of 16 indicates that the route is down. proxy, private and static To support the Routing Information Protocol (RIP) the route command utilizes the proxy, private and static key words. These words can be used in any order following metric.

MX2 Reference Guide E-EQ-MX2RG-L-ARC Radio PC Card Configuration 51

Proxy ARP should be used with care and not in conjunction with RIP. When more than one host responds to an ARP request, it can cause confusion and even lead to system crashes. This is possible in situations where more than one gateway implements Proxy ARP to a common destination. When “RIP advertising” is selected, all interfaces advertise all routes except those routes making use of that specific interface (split horizon) and routes marked private. A route which is dropped as a result of a RIP update or which becomes unavailable as a result if its associated interface going into the down state, is immediately advertised as being infinite (metric = 16) and is not advertised until it becomes available again. In order for an interface to be used for advertising, a route without a gateway using that interface must be available. The advertisement is sent as a subnet broadcast using the net mask of the host and the IP address of the interface. When “RIP using” is selected, routes are updated according to received RIP advertisements. Routes added or amended as a result of RIP, have a timeout associated with them. If another RIP advertisement is not received during that time, the route is dropped. A route is also dropped if an advertisement of infinity (metric = 16) is received. To prevent dropping a route, it must be marked as static. The metric of a route marked static is never updated by a RIP advertisement. Instead a duplicate route is added before the static route. If the duplicate route is dropped as a result of a timeout or RIP, the static route is used again.

Examples route add default ipx0 route add unix_net eth0 route add unix_host ipx1 unx_gate route add unix_net2 eth0 /eth 1 route add unix_ net ipx0 unx_ gate route add subnet/26 eth0 sub_gw route drop unix_net route can specify a Proxy ARP on a route, as follows: route add net interface gateway metric [proxy] When using Proxy ARP, gateway and metric must be specified. If no gateway is used, none can be specified. For example: route add 192.6.1.0 ifx25 none 5 proxy tcp tcp commands display or set various TCP operating parameters. The TCP configuration commands are put into SOCKETS.CFG.

Syntax tcp irtt [time] tcp lport [port_number] tcp mss [size] tcp retry [number] tcp rtt [time] tcp smss [size] tcp timemax [time] tcp window [size]

E-EQ-MX2RG-L-ARC MX2 Reference Guide 52 Radio PC Card Configuration

Parameters time time is the new time value in seconds, or milliseconds if “ms” is appended to the number, as in 2000ms. port_number port_number is the local port starting number. size For tcp mss, size is the maximum segment size in bytes sent on all outgoing TCP connect requests (SYN segments). size tells the remote host the size of the largest segment that may be received by this host. When changing the MSS value, any existing connections remain unchanged. For tcp smss, size is the send maximum segment size in bytes sent on all outgoing TCP connect requests. This limits the size of the largest segment that may be sent by this host. When changing the SMSS value, any existing connections remain unchanged. For tcp window, size is the size of the receive window in bytes for any new TCP connections. Existing connections are unaffected. number number is the number of retries attempted without receiving an acknowledge from the remote host before the connection is broken. If the value exceeds 255, it implies an infinite number of retries; such a connection does not time-out. The default value for number is 6.

tcp irtt Sub-command tcp irtt displays or sets the initial round-trip-time estimate. When specified without an argument, the command displays the current values of TCP parameters including the initial round-trip-time in milliseconds. time is the initial round-trip-time (IRTT) estimate and is used for new TCP connections until the actual value can be measured and adapted to. By increasing this value when operating over slow communication links, unnecessary retransmissions that otherwise occur before the smoothed estimate value approaches the correct value are minimized. The system default is 5000 milliseconds. To affect incoming connections, tcp irtt should be executed before the servers are started.

Example tcp irtt 120

Sample Output TCP: IRTT 5 ms Retry 6 MSS 1460 SMSS 1460 Window 2920

tcp lport Sub-command tcp lport specifies the local port starting number. When specified without a number the current value of the next free local port number is displayed.

Example tcp lport 2004

MX2 Reference Guide E-EQ-MX2RG-L-ARC Radio PC Card Configuration 53

Sample output Lport = 2004

tcp mss Sub-command tcp mss displays or sets the TCP maximum segment size in bytes. When size is not specified, the current values of the TCP parameters, including the maximum segment size, are displayed. It is recommended to reduce the MSS and SMSS on bad network connections.

Example tcp mss 1460

tcp retry Sub-command tcp retry displays or sets the retry count before a connection is broken. When specified without the number parameter, tcp retry displays the current values of TCP parameters, including the retry count.

tcp rtt sub-command tcp rtt replaces the automatically computed round-trip time (RTT) for the specified connection with the time in milliseconds. Sockets calculates the RTT as a smooth average of past measured RTTs, starting with the IRTT on a new connection. To get the current RTT in use for a connection n, use the tcp status n command that will give the smoothed average RTT indicated by SRTT. Because tcp rtt provides a manual override of the normal back-off retransmission timing mechanisms, it may be used to speed up recovery from a series of lost packets.

Example tcp rtt 4 100

tcp smss sub-command tcp mss displays or sets the TCP send maximum segment size in bytes. When size is not specified, the current values of the TCP parameters, including the SMSS, are displayed. A small SMSS causes the remote to reduce its segment size. tcp mss can reduce the MSS and SMSS on bad network connections with high loss rates or where large packets get lost.

Example tcp smss 512

tcp window sub-command tcp window displays or sets the default and maximum receive window size. When specified without the size parameter the current TCP parameters, including the current window size, are displayed.

Example tcp window 2920

E-EQ-MX2RG-L-ARC MX2 Reference Guide 54 Radio PC Card Configuration

tcp timemax sub-command tcp timemax sets the maximum duration of a tcp retry. If a value greater than 255 seconds is specified, connections will never timeout. This is very useful in wireless applications where nodes roam in and out of service.

Example tcp timemax 2000ms

MX2 Reference Guide E-EQ-MX2RG-L-ARC RF Throughput, Performance and Troubleshooting 55

RF Throughput, Performance and Troubleshooting

Because of the complicated nature of wireless LAN technology, problems occasionally arise. This section provides general information about performance and addresses some problems that might arise during setup or use of a wireless network with RF units. This should be your first resource in case of trouble.

Power Management at the Proxim RangeLAN2 Access Point Proper setup of the access point (AP) is essential to RF power management. Even with the MX2 set up for maximum power savings, the batteries can become drained quickly if the AP is not configured properly.

MU Access Control For environments in which multiple RF networks overlap, you can use an authorization table to prevent RangeLAN2 APs from accessing RF cards on other networks. This list contains media access control (MAC) addresses of mobile units that are allowed to associate with the AP. See the AP user’s guide for more information about MAC addresses and for information about the authorization table.

Message Filtering Network packets include a protocol type (IPX, IP, ARP broadcast, NetBIOS, etc.) in the header field. By filtering out unwanted protocol messages, you can prevent the AP from sending these packets to the MX2. This will reduce the amount of times the radio cards have to wake up out of doze mode to service incoming packets. It can be especially important to filter out broadcast messages. These types of packets, which are generically addressed to all computers on a system, may force the MX2 to operate continuously in full receive mode, even when the data is not relevant to the MX2. If the MX2 does not turn off automatically after the preset timeout, it is an indication that the radio card is receiving broadcast messages and is unable to go to sleep. The Proxim AP user interface for filtering packets allows you to select the type of packets that will be filtered by selecting from a list of possible types. The best method with the Proxim RangeLAN2 access point is to turn on filtering for every packet type that you know you won’t use. For example, if the access point is hooked up to a TCP/IP network, you would set TCP/IP to Not Filtering and all other protocols to Filtering. In a NetBEUI environment, turn off the Filter NetBEUI option, and turn filtering on for all the rest of the protocols. ARP Broadcast packets should always be turned off, unless your application requires them, to prevent broadcast messages from waking up the MX2.

Note: For more information on packet filtering, see the RangeLAN2 access point manual or your network administrator.

E-EQ-MX2RG-L-ARC MX2 Reference Guide 56 RF Throughput, Performance and Troubleshooting

Site Survey Many companies have an existing Ethernet or wired LAN infrastructure and want to be able to extend that capability to wireless nodes. This is accomplished by attaching an access point to the wired LAN, allowing the wireless clients to access the network resources. MX2s, like other 386-compatible DOS computers, can be connected to networks. With RF models, radio signals between the MX2s and the AP replace the wires connecting the nodes to the network. A site survey is an important part of setting up a wireless network. Contact your LXE representative. For most office environments, a site survey is not necessary. For large, industrial environments requiring multiple APs, however, you should perform a site survey before installing a RangeLAN2 network system. Run Proxim’s RL2SETUP.EXE program on a laptop using a RangeLAN2 card. The purpose of a site survey is to calculate the most effective number of access points at a site and the best placement and positioning of antennas for optimal reception of radio signals. This is done by identifying areas where transmission failures occur. As each site is unique, the surveyor needs to consider the exact conditions, as they will appear in the final installation. In addition to such climate factors as moisture, excessive heat, and dust, a site survey can also be affected by physical obstructions and electromagnetic interference. Also important is the identification of potential cabling, connector, or power problems.

Throughput and Performance The bandwidth on a radio network is constant for a given network. Therefore, the more active RF units using the same frequency- hopping pattern, the slower the throughput of any one unit. If this is a problem, you should install additional access points. Radio signals may reflect off some obstacles and be absorbed by others. An RF unit with an unobstructed line of sight to the access point antenna can successfully transmit and receive signals at distances up to 1000 feet. In an environment that includes such obstructions as cubicle walls typically used in modern offices, the range is reduced significantly, with a maximum distance of 500 feet. Where signals must penetrate office walls, the maximum distance may be only 300 feet. Many other factors also affect performance of wireless LANs, including the following: • Transmitter power • Receiver sensitivity • Interference caused by noise, receiver desensitization, spurious responses, and intermodulation • Shadowing • Multipath fading • Consumer products in use in the coverage area Some of these factors can be sensed during a site survey and be avoided.

MX2 Reference Guide E-EQ-MX2RG-L-ARC RF Throughput, Performance and Troubleshooting 57

Operational Problems This section lists solutions to problems that can occur with an RF unit.

The drivers won’t load, or the unit locks up when the drivers load.

Be sure the RangeLAN2 PC card is correctly installed in the radio card slot before turning the unit on. Do not remove or insert any PC card while the MX2 is on.

The MX2 seems to lock up for four or five seconds after it is turned on.

Every time a MX2 is turned on, it must initialize the PC card. Wireless LAN PC cards commonly take four or five seconds to initialize. After the card is initialized, the unit should function normally.

The MX2 cannot communicate with a NetWare server.

The MX2 and the server may be using different frame types. Make sure that the frame type in your NET.CFG file matches the server’s frame type.

The MX2 cannot communicate with another machine on the network.

The MX2 may not have the same domain and security ID as the other machine.

The MX2 does not shut down properly when I remove the PC card or take out the batteries.

Do not remove a PC card or the batteries while the MX2 is on or immediately after turning it off. When you turn the unit off, it suspends the RF driver, a process that can take one or two seconds. If you remove the PC card or the batteries before the driver is suspended, the unit may be left in an unstable state and may need to be reset.

The MX2 never turns itself off automatically, even when the time-out value is correctly set.

The radio may be receiving broadcast messages from the access point. See “Power Management at the RangeLAN2 Access Point”, for information on filtering messages.

E-EQ-MX2RG-L-ARC MX2 Reference Guide 58 RF Throughput, Performance and Troubleshooting

Problems with DOS Drivers Some problems may occur in the DOS environment. Many problems can be caused by inappropriate memory, I/O, or IRQ settings for the MX2. If changing those settings in the NET.CFG file doesn’t solve the problem, consult the following list of symptoms to identify other possible causes. Contact your systems administrator if you need additional help.

ODI driver does not install or does not work

• Memory range not reserved • Incompatible protocol manager and stack • Improper linking in NET.CFG file • Memory, I/O, or IRQ setup conflicts with other installed software and hardware

TCP/IP fails

• Incorrect IP/subnet address • Incorrect domain; check for MU association

Nothing happens after installation of the network software (no login, cannot find server, no TCP connection)

• Incompatible firmware and driver versions • Memory, I/O, or IRQ setup conflicts with other installed software or hardware • MU is out of range • All cards must have matching security IDs to communicate

Slow or erratic performance

• Out of communication range • Faulty antenna, antenna connector, or cable

Driver does not install, or driver hangs during installation

• Incompatible firmware and driver versions • Memory range not reserved • Memory range does not match setting in NET.CFG file • Memory range is too small (use I/O mode if memory is restricted) • Memory, I/O, or IRQ setup conflicts with other installed software or hardware

MX2 Reference Guide E-EQ-MX2RG-L-ARC

Chapter 3 Software Configuration

Introduction

This chapter details the default contents of the disk drives and the organization of system software on the MX2. It also includes descriptions of two standard software configurations.

BIOS and DOS The MX2 uses a modified version of General Software’s BIOS with Datalight’s ROM-DOS. Both products are burned into system flash in a single 256K image. The A drive is included in the image, physically addressed just below the BIOS image. ROM-DOS uses the Datalight command.com processor. This processor is fully Microsoft 6.2 compatible, except that it occupies about half the space in memory. In addition, drive C contains Datalight DOS files in a DOS subdirectory.

DOS Key Functions Not Supported on the MX2 Prnt Scrn A function that is available at the DOS prompt on a desktop PC. The Prnt Scrn as a system function requires a parallel port and the MX2 has only serial ports. Sys Req A function that is available at the DOS prompt on a desktop PC. Sys Req is for use in a multi-tasking environment to switch between various running applications. The MX2 is not a multi-tasking computer, nor is DOS in general considered a multi- tasking environment.

PC Card and RF Networking Software PC card device drivers and utilities as well as RF networking solutions are installed on drive C (the flash drive). • Default IRQ for PC card is 7. • Default PC card COM port is COM 2.

E-EQ-MX2RG-L-ARC MX2 Reference Guide 60 Disk Drives and Files

Disk Drives and Files

The MX2 has the following drive structure: Drive A is a read-only flash drive. The contents of this drive cannot be changed. Drive B is a read-only flash drive. (Normal operation will not require updating of this drive.) Drive C is a resident flash disk drive that is accessed with the FLASHDSK.SYS device driver. You can use this drive to store applications and data. Drive D is a RAM disk accessed with the VDISK.SYS device driver. This drive can be used to store applications as well as data. However, you should take great care in selecting files for this drive. As with any RAM drive, its contents will be lost if power is removed. Additional drives are mapped to ATA flash PC cards or to network drives via radio frequency (RF). This organization provides an easy-to-use, extensible system that allows a high degree of performance, usability, and customization. The following sections more fully describe the contents and intended uses of each of the MX2’s drives.

Drive A Drive A is a disk image that is located in flash along with the BIOS and ROM-DOS. A read-only drive, it is intended to remain secure throughout the life of the unit. Drive A contains the following files:

AUTOEXEC.BAT the first file in the startup sequence

CONFIG.SAF the first file in the safe-boot sequence

CONFIG.SYS the first file in the boot sequence

REV.COM the utility that reports the firmware revision The CONFIG.SYS and AUTOEXEC.BAT files contain only basic commands that the unit needs to run correctly. Both files chain to their respective counterparts on the B drive, as described in the next section. The CONFIG.SAF file is used in the safe-boot sequence.

REM ************************************** REM Initial CONFIG.SYS file for REM starting the system. REM **************************************

NEWFILE = B:\CONFIG.SYS

REM ********************************* REM Initial CONFIG.SYS for safe boot. REM ********************************* NEWFILE = B:\CONFIG.SAF

Figure 3-3 CONFIG.SAF File on Drive A

E-EQ-MX2RG-L-ARC MX2 Reference Guide 62 Disk Drives and Files

Drive B Drive B is a disk image that is located in flash. A read-only drive, it is intended to be used to store mandatory utilities and initialize the boot process. During normal use this drive will not be updated. Drive B has no subdirectories. See Chapter 4, “Commands”, for ROM-DOS command syntax.

AUTOEXEC.BAT the second file in the startup sequence. CFGDEV.SYS the system-parameter-configuration device driver. CFGIO.EXE the utility for loading fonts and keypad layouts. COMIO.COM the utility for redirecting input and output to the serial port. COMMAND.COM the DOS shell. CONFIG.SAF the second file in the safe-boot sequence. CONFIG.SYS the second file in the boot sequence. COREUPD.COM the utility that updates the firmware image. DECODE.SYS the bar-code-decoding device driver. FLASHDSK.SYS the resident flash disk device driver. FORMAT.COM the disk-reformatting utility. FUNCTEST.COM the functional test for system components. HIMEM.SYS the device driver for accessing extended memory. LD.BAT the batch file for RESPONSE.BAT processing. LOCK.COM the utility for locking or unlocking the resident flash disk and RAM disk. ORGANIZE.COM the utility for reorganizing flash disk data. PM.COM the power-management utility. REV.COM the utility that reports the firmware version. UMBLINK.EXE the device driver for accessing upper memory blocks. VDISK.SYS the RAM-disk device driver. The CONFIG.SYS file will load the FLASHDSK.SYS driver to create the C drive and the VDISK.SYS driver to create the D drive. It will then load DECODE.SYS and CFGDEV.SYS before chaining to its counterpart on drive C. The AUTOEXEC.BAT file will chain to its counterpart on drive C, except during a safe boot.

MX2 Reference Guide E-EQ-MX2RG-L-ARC Disk Drives and Files 63

The purpose of the CONFIG.SAF file is to provide a minimal boot configuration that preserves the flash and RAM drives. When the safe-boot sequence is initiated, the CONFIG.SAF file is processed instead of the CONFIG.SYS file. This prevents chaining into the drive-C initialization files by omitting the NEWFILE = C:\CONFIG.SYS command. It also eliminates the loading of the DECODE.SYS and CFGDEV.SYS drivers.

E-EQ-MX2RG-L-ARC MX2 Reference Guide 64 Disk Drives and Files

Drive C Drive C is a resident flash disk drive that is accessed via the FLASHDSK.SYS device driver. By default, this drive is configured to have full read and write access. The default CONFIG.SYS and AUTOEXEC.BAT files reside here. You can modify these files to customize the system for an application. They will be called after the CONFIG.SYS and AUTOEXEC.BAT files on drives A and B are processed. By default, this software is installed on the C drive. If the unit is intended to be used with PC cards, then the Phoenix PC card drivers are installed in the PCM subdirectory on the C drive, and the proper entries will be transferred into the CONFIG.SYS and AUTOEXEC.BAT files. The exact configuration of files and the contents of the CONFIG.SYS and AUTOEXEC.BAT files will change according to the configuration of the unit. For RF capability, additional files for network connectivity would be required. These might include a TELNET program or peer-to-peer networking tools, depending on what you choose to install. If something happens to a unit and data integrity becomes questionable, use the CHKDSK utility to detect and correct errors on drive C. You can also use ORGANIZE.COM (on Drive C in the MX2) to recover unused sectors. See Chapter 4, “Commands”, for ROM-DOS command syntax.

Root Directory Files

AUTOEXEC.BAT Called after the AUTOEXEC.BAT files on drives A and B are processed.

CONFIG.SYS Called after the CONFIG.SYS files on drives A and B are processed.

DOS Directory Files See Chapter 4 “Commands” for function descriptions of the following files:

ANSI.SYS MODE.COM

CHKDSK.COM NED.CFG

CHOICE.COM NED.EXE

COMMAND.CO REMDISK.EXE M

FORMAT.COM REMSERV.EX E

MEM.EXE REV.BAT

MX2 Reference Guide E-EQ-MX2RG-L-ARC Disk Drives and Files 65

PCM Directory Files

CNFIGNAM.EXE Specifies which PCM Plus configuration parameters are to be used, based on the selected boot configuration.

PCM.INI Defines system resource requirements for all boot configurations which contain PCM Plus. When a boot configuration is specified, CNFIGNAM identifies the selection as CONFIG.SYS is loaded and requests the relevant configuration information from the PCM.INI file.

PCMATA.SYS Device driver enables the system to access ATA-configured PC cards as IDE hard drive devices using an IDE partition table.

PCMCS.EXE Must be loaded directly after Socket Services. Coordinates access to the PC cards and allocates PC system resources among client drivers.

PCMSS400.EXE PCM socket services are located in this driver. The purpose of socket services is to provide a layer of software support to the actual PC hardware that controls PC-compatible sockets for PC cards.

Agent Directory Files The SNMP agent files are loaded on MX2’s with a 2.4GHz radio.

Please refer to the “SNMP Agent Reference Guide” and “Client Configuration Manager Reference Guide” for more details on the SNMP agent. Please refer to the following section titled “Avalanche” when Avalanche is installed.

AGENT.EXE Diagnostic agent. Provides limited access to the LXE Private MIB.

CFGAGENT.EXE Configuration agent. Provides full access to the LXE Private MIB.

REV.BAT Displays current revision level.

RFPARSE.EXE Used by PCRFLIB to obtain configuration settings. May or may not be present.

Terminal Emulation Files

Please refer to the specific Terminal Emulation’s reference guide for complete instructions. Some MX2’s do not have terminal emulation (TE) files and may or may not have a radio card. When a need exists to convert the unit to a TE unit or a different radio card, contact LXE Customer Services for assistance. Following are the directory names containing the TE program files: \APLUS ANSI Plus with 2.4 GHz radio \IBM24 TN3270 with 2.4 GHz radio \IBM24 TN5250 with 2.4 GHz radio Note: Dual Terminal Emulation (Dual TE) is not supported on this device.

E-EQ-MX2RG-L-ARC MX2 Reference Guide 66 Disk Drives and Files

TE Selection Menu The TE Selection menu is generally not displayed on an MX2 computer since dual TE’s are not supported. However, the TE Selection Menu may also be used to display multiple Autologin hosts for some TE’s. Please refer to the appropriate terminal emulation reference guide and the “DOS Autoconfigurator Instructions” for more details.

Menu Customization The system administrator may change almost every facet of the menu display by modifying the variables found at the top of TESELECT.BAT. Details on modifying the TESLECT.BAT file are included in the “DOS Autoconfigurator Instructions”.

Drive D Drive D is a RAM disk drive. By default, this drive resides in extended memory and is sized 1MB less than the total RAM in the unit. Drive D can be used for short-term data storage. Programs that need to be loaded into memory and then removed from memory quickly can also be located there. The drive can also be used for scratch disk space or temporary files. The MX2 preserves the data on drive D between warm or cold boots by checking for an existing RAM disk. However, only minimal checking is performed on any disk that is found. If something happens to a unit and data integrity becomes questionable, you should use the CHKDSK utility to detect and correct errors on drive D.

Drive E Drive E is the ATA flash card. The PC card looks like a hard disk drive to the operating system and the user. More flexible than flash disk drive C, it can be used for safer and more permanent bulk storage of batch data than the RAM disk (drive D). This drive exists only on systems configured to use ATA flash cards. Drive E could also be a peer-to-peer or client-server network drive that is accessed through an RF or Ethernet network card link. This option allows the developer to make many network drives (drives E, F, etc.) available to applications.

MX2 Reference Guide E-EQ-MX2RG-L-ARC Data Entry 69

Data Entry

Note: The MX2 will not run Microsoft® Windows® products i.e. Windows 3.1, Windows For Workgroups, Windows 95, Windows NT, etcetera. The LXE MX2 computer accepts data entry from the keyboard, barcode scanner and the Infrared input port when an LXE Terminal Emulation (TE) program is running and on batch (non-TE) units.

Keyboard Data Entry Once the terminal emulation program is started, data can be entered with the MX2 keypad. Keyed data can be entered into a data field and transmitted to the host. You might respond to a prompt sent by the host application with a keypad entry, such as a menu listing choices for your next action.

Barcode Data Entry The MX2 supports data entry using the barcode scanner at the top of the unit. Keyboard data entries can be mixed with barcode data entries.

Infrared Port Data Entry The MX2 accepts input from the IR port. The MX2 processes data from the IR port the same way it processes keyed data. The data is entered at the cursor position, and the data is subject to all of the barcode/RS-232 input menu parameters, such as truncate.

Terminal Emulation

Note: Narrowband and spread spectrum 900MHz radios are not supported at this time. For details concerning future capabilities, contact the LXE Product Marketing department. All terminal emulation radio controlled data flows and exchanges are over the radio to the 64XX or 65XX units, then to the computer network and then to a host computer. The LXE Network Management System, as part of the wired network, can remotely configure the MX2’s terminal emulation parameters.

Note: MX2’s with 64XX series 2.4GHz spread spectrum radios communicate only with 64XX Access Points with installed 64XX 2.4GHz radios.

Note: MX2’s with 65XX series 2.4GHz spread spectrum radios communicate only with 65XX Access Points with installed 65XX 2.4GHz radios. Please refer to the system specific terminal emulation reference guide for instruction when using a MX2 in a specific TE environment. A list of LXE reference guides is located at the end of Chapter 1 “Introduction and Specifications” in the section titled “Manuals”. LXE’s terminal emulation programs that are compatible with the MX2 computer are:

SNMP DOS Agent

The SNMP DOS agent resides in the C:\AGENT directory of mobile computers. By default, the agent is placed into memory as a TSR and uses approximately <50k of memory. When the agent is not being polled, it is invisible to the user. When it is being polled, there is a slight delay, depending on how much data is being retrieved by the agent.

For information on disabling the SNMP DOS agent, please refer to the “DOS Autoconfigurator Instructions”. For more information on agent operation, please refer to the “SNMP Agent Reference Guide” and “Client Configuration Manager Reference Guide”. These manuals are available on the LXE Manuals CD.

E-EQ-MX2RG-L-ARC MX2 Reference Guide 78 Avalanche

Avalanche

Note: Wavelink Avalanche is not designed to run on a device with a 900MHz or Narrowband radio.

Note: If the device is configured to use Avalanche for network settings, manual changes made to NET.CFG and SOCKET.CFG may be overwritten. Avalanche may or may not be installed on your mobile device. Refer to this section for important information relating to Avalanche running on an MX2 with a 2.4GHz radio. Contact your LXE representative if Avalanche is needed and your mobile system has not been upgraded to the required minimum software baseline revision levels. For complete instruction when using Avalanche please refer to the “Wavelink Avalanche for DOS Reference Guide” on the LXE Manuals CD.

Minimum Software Baseline The minimum software revision level (baseline) must be loaded on the mobile device in order to use Avalanche: Operating System...... 232XGSYS.02A LXE Agent...... AGNTGD00.01C Core...... 232XGCOR.01C Avalanche Number ...... AVA2GD01.01A Cisco 350 Radio Driver ...... C802GD35.01H Lucent Radio Driver ...... L802GD01.01P Symbol 4121 Radio Driver ...... S802GD21.01E

Upgrading the MX2 If an LXE computer does not meet the minimum baselines specified above, it must be manually upgraded to the baseline before it can be used with Avalanche. The older G-Number software should be manually deleted from the LXE computer before the new G-Number is installed.

Copying the new G-Number software to the LXE computer without first deleting the ! old G-Number software may lead to insufficient disk space on the LXE computer. This is especially important for LXE Agent, Radio and MX2 Core G-Numbers.

\APLUS Location of optional TE files * \IBM24 Location of optional TE files * \LDS24 Location of optional TE files * * Although Avalanche can be used to update the files contained in these directories, the file structure is not changed by the addition of the Avalanche enablers.

\AGENT When Avalanche enablers are installed, only the SNMP Diagnostic agent, AGENT.EXE is installed. The configuration agent, CFGAGENT.EXE is not installed.

\AVA This directory contains the Avalanche enablers and supporting files. Users must not make changes to the contents of this directory. When an updated enabler is loaded, it will change the contents of the \AVA directory. The boot process checks for a newer version of the enabler before loading the enabler in the \AVA directory. Since the MX2 has limited disk space, updates to the enabler on the MX2 replace the original enabler files.

\APPS This directory is used by Avalanche to track the revisions of software on the LXE DOS computer.

Chapter 4 Commands

Introduction

This chapter describes the Datalight ROM-DOS commands that are loaded in the MX2 by LXE. The information in this chapter is taken from Datalight’s “ROM-DOS 6.22 User’s Guide” and is used by permission.

ROM-DOS Commands

Each entry includes an explanation of the command’s purpose, the command entry syntax, remarks, and examples. Where applicable, command syntax and parameters are given. Parameters may be supplied using either uppercase or lowercase letters, and the hyphen (-) may be substituted for the forward slash (/). Each command also has a label to designate whether it is an internal or external command. Internal commands are part of the command processor program, COMMAND.COM. These functions are available only while COMMAND.COM is running. External commands are actually stand-alone utility programs. They are independent from COMMAND.COM.

ANSI.SYS

Type Installable Device Driver

Purpose ANSI.SYS is a console device driver that allows you to support ANSI codes on the local display.

Syntax Device=ANSI.SYS [options]

Remarks ANSI.SYS supports standard ANSI escape sequences. ANSI.SYS writes directly the screen when using text video mode.

Options The /K option forces use of the extended keyboard BIOS calls which sense F11 and F12. The /X option lets you redefine the extended keys independently. The /S option disables the keyboard redefinition feature. The /Tnn option indicates that the video mode nn is a text mode. By default, modes 0, 1, 2, 3 and 7 are text modes.

E-EQ-MX2RG-L-ARC MX2 Reference Guide 82 ROM-DOS Commands

Examples DEVICE=ANSI.SYS This example loads ANSI.SYS with default settings. DEVICE=ANSI.SYS /T54 /S Load ANSI.SYS with mode 54h as a video text mode and disable keyboard redefinition.

ATTRIB.EXE

Type External

Purpose The ATTRIB command either displays or modifies the attribute of a file.

Syntax ATTRIB [+ ¦ -][option][filespec]

Remarks The file attributes define the characteristics of a file. They determine if a file may be deleted or modified, or if it is archived. The ATTRIB command is used to manage these file attributes. Wildcard characters may be used in the ATTRIB filespec. The ATTRIB command will modify file attributes if modify commands are given to ATTRIB. The modify commands are:

Command Description

+/- Add(+) or remove(-) attribute

A Archive attribute

C Clear all attributes

H Hidden file attribute

R Read only attribute

S System file attribute

If no modify commands are found by ATTRIB, then the files are displayed along with the file names and their current attributes.

MX2 Reference Guide E-EQ-MX2RG-L-ARC ROM-DOS Commands 83

Examples ATTRIB will add the read-only attribute to the file myfile.dat. ATTRIB +r myfile.dat ATTRIB will remove the read-only attribute and the archive attribute for all files with the DAT extension. ATTRIB -a -r *.dat ATTRIB will display the attributes of all files with the DAT extension. ATTRIB *.dat

CHKDSK.EXE

Type External

Purpose The CHKDSK command checks the disk directories and File Allocation Table (FAT) and displays a disk and memory report.

Syntax CHKDSK [d:][path][filespec][/C] [/F] [/V]

Remarks CHKDSK examines a disk and determines if the disk has any errors in the File Allocation Table (FAT) and will optionally fix errors.

Options The /F option causes CHKDSK to fix errors on the disk if any were found. The errors that can be found are directory or FAT errors. If the /F is not specified then CHKDSK acts as if it will fix the disk, but the corrections will not be written out to the disk. If errors are detected, you will be prompted with a message similar to the following: 15 lost allocation units found in 5 chains. Convert lost chains to files?

If you answer Y for Yes, each lost chain will be written to a file in the root directory of the current default drive. Each file will have the name filennnn.chk. nnnn will be a sequential number. The first chain will be in FILE000.CHK. These files can be verified to see if they contain valuable information, and then deleted if desired. Answering N for No to the above prompt, CHKDSK will still make the corrections however the lost chains will not be saved to the disk. The /C option allows CHKDSK to correct errors without user confirmation. This option must be used along with the /F option for corrections to be made. The /V option causes CHKDSK to display each path and file as it is processed. If a file specification is specified, then CHKDSK displays all files matching the specification that have noncontiguous data areas on the disk. Files that are stored in noncontiguous areas, especially .exe files, have slower disk access times. If CHKDSK reports a large number of files with this problem, a utility program that optimizes the files and free space on your disk should be used.

E-EQ-MX2RG-L-ARC MX2 Reference Guide 84 ROM-DOS Commands

After checking the disk, CHKDSK displays any error messages followed by a report on the state of the disk that was checked. An example of the report is shown below. Volume ROM-DOS created June 1,1990 1:00a Volume Serial Number is 190E-4AA2 362496 bytes total disk space 0 bytes in 1 hidden files 6144 bytes in 2 user files 356352 bytes available on disk 655360 bytes total memory 595360 bytes free CHKDSK does not wait for a disk to be inserted before the checking is initiated nor does it repair any errors.

Examples CHKDSK will check the integrity of drive A. The report will be printed to the console. CHKDSK a: CHKDSK will check the integrity of RAM disk D. The report will be saved in a file called DRIVE_D.RPT. CHKDSK d: >drive_d.rpt

COMMAND.COM

Type External

Purpose Start a new command processor.

Syntax COMMAND[device][/E:number][/K:filename][/P][/C string][/MSG]

Remarks This command starts a new copy of the ROM-DOS command processor. The command processor is the program that has all the internal DOS commands in it. Starting a new command processor will also produce a new environment. The size of the environment is 128 bytes by default, but it can be changed using the /E switch. Command and its arguments can also be used in a SHELL= statement in your config.sys file. See the full description of SHELL for more details.

Options The device option specifies that COMMAND.COM should use a different device, such as AUX, for input and output. The /E:number switch sets the environment size. Number represents the size of the environment in bytes. Number must be in the range from 160 to 32768. All other values will be ignored and the default value of 256 will be used. ROM-DOS will round the value entered up to the nearest multiple of 16.

MX2 Reference Guide E-EQ-MX2RG-L-ARC ROM-DOS Commands 85

The /K:filename option tells the command processor to run the specified filename and then display the ROM-DOS command prompt. It is not recommended that this option be used in a CONFIG.SYS SHELL= statement. The /P switch causes COMMAND not to exit, or in other words, to remain permanent. The /P switch should be used only when command is used in a CONFIG.SYS SHELL statement. The /c string switch causes COMMAND to execute the command in string and then terminate. The string command can be any internal or external command. The /MSG option indicates that all error messages should be stored in memory. This option is recommended only for diskette based systems. ROM-DOS keeps many of its error messages in the resident part of COMMAND.COM rather than using valuable memory to store them. If an error message is needed and you have loaded ROM-DOS from a diskette, the message will only be available if the boot disk is still in the drive. By using the /MSG option, the messages will be available in memory at all times. The /P option must be used along with the /MSG option.

Examples The following command will cause a new copy of COMMAND to be executed. It will perform a DIR command on the C drive and then exit back to the previous Command Processor. COMMAND /C DIR C: The following example shows loading of a permanent copy of command with an environment size of 256 bytes. SHELL=C:\COMMAND.COM /P /E:256

DELTREE.EXE

External Command The DELTREE command deletes one or more directory trees or individual files.

Syntax DELTREE [/Y] [drive:]path [[drive:]path[...]]

Remarks /Y prevents DELTREE from prompting before deleting. [drive:]path indicates the name(s) of the file(s) or directory tree(s) to delete. Wildcards are allowed.

Examples Datalight DELTREE deletes one or more directory trees. For example, to delete all files and directories in the tree C:\TEMP, enter DELTREE C:\TEMP. You can also use DELTREE to delete individual files, one at a time, using wildcards. For example, to delete selected files in the current directory, enter DELTREE *.* DELTREE then prompts you for each file it finds, allowing you to choose whether to delete them.

Caution: Take care when using wildcards with DELTREE. DELTREE deletes all specified files and subdirectories regardless of their attributes. Multiple files and/or subdirectories may be specified.

E-EQ-MX2RG-L-ARC MX2 Reference Guide 86 ROM-DOS Commands

FORMAT.COM

External Command The FORMAT command initializes a disk so ROM-DOS can access files on that disk. A disk must be formatted before ROM-DOS can use it.

Syntax FORMAT [drive:] [/options]

Remarks FORMAT initializes the disk and directory of the specified drive. The size of the formatted disk is the largest possible size that the specified drive supports, unless a different size is specified via a command line option.

Options The /4 switch causes the floppy disk to be formatted as a 360KB disk even if the drive is a 1.44MB, 2.88MB, or 1.2MB drive. The /7 switch causes the floppy disk to be formatted as a 720KB disk even if the drive is a 1.44MB or 2.88MB drive. The /B option causes FORMAT to used BIOS Int 13h calls. By default, FORMAT checks the DOS version, and if it is DOS 5.0 or higher, it uses the floppy device driver to do the format. Using the /B option forces FORMAT to bypass the floppy or hard disk controller and use BIOS calls. /B makes FORMAT device independent. The /C switch causes FORMAT to format one disk without user input. The disk is assumed to be in the specified drive, and FORMAT exits immediately when the format is complete. This switch is useful in batch files or programs that require a formatted disk without user input. The /F:size option specifies the size of the floppy disk to be formatted. Available size values are 360, 720, 1.2, 1.44, and 2.88, and are entered as /F:size. For example, /F:1.2. The /H switch causes the system files not to be hidden or write-protected. This can be used along with the /S option. The /I option forces FORMAT to use IOCTL calls and never use BIOS calls. Normally, FORMAT first tries to access the device driver IOCTL calls to format the disk. If this fails, BIOS calls are used (unless the /B option is specified). BIOS calls are always used for DOS 3.3 and earlier. The /Q option causes FORMAT to do a quick format. A quick format reinitializes the disk, deleting each file and subdirectory from the disk. A quick format can only be performed on a previously fully formatted disk. The /S switch causes FORMAT to copy the ROM-DOS system files, ROM-DOS.SYS and COMMAND.COM, onto the disk. The file ROM-DOS.SYS is renamed and stored on the disk as files IBMBIO.COM and IBMDOS.COM, which are stored as hidden files, unless the /H option is used. The /V:LABEL switch causes FORMAT to place a volume label on the disk. If the volume label is not provided on the command line, you are prompted for the volume label once the format is complete. The /[ switch causes FORMAT to run without display of the sign-on message.

MX2 Reference Guide E-EQ-MX2RG-L-ARC ROM-DOS Commands 87

If FORMAT encounters an error, the exit code returned to DOS indicates the type of error. The error codes are listed in the following table.

Error Level Type of Error

0 No error encountered

1 Invalid drive

2 Unsupported drive format

3 Attempted hard drive format (unsupported)

4 Write-protect error

HIMEM.SYS

Installable Device Driver The HIMEM.SYS device driver manages extended memory and the High Memory Area (HMA) in a 286, 386 or greater, or PS/2 systems. HIMEM prevents programs from simultaneously using the same area of memory for two different purposes. HIMEM supports the Extended Memory Specification (XMS) 2.0. HIMEM is installed as a device driver in CONFIG.SYS.

Syntax DEVICE = [d:] [path] HIMEM.SYS [/machine:n] [/A20[+]] [/PS2] [/CONTROLA20:OFF]

Remarks The HIMEM driver can be used to allow ROM-DOS to run in High Memory. HIMEM supports a default of 32 handles. HIMEM should not be used with older versions of Datalight’s VDISK. Current versions of VDISK use XMS memory if it is available. HIMEM recognizes PS/2-style A20 line control and determines whether to use the PS/2 A20 control or the AT A20 control method automatically by calling Int 15h, function C0h (get system configuration). This automatic detection can be overridden with the /Machine:n, /A20, A20+, or /PS2 command line switches in the event that the auto detection on a given system fails. /Machine:1 and /A20 both designate the PC AT A20 control method. These switches instruct HIMEM not to wait for the A20 line to settle. /Machine:2 and /PS2 both designate the PS/2 control method. /A20+ is similar to /A20 but instructs HIMEM to wait for the A20 line to settle. /Machine:3 designates support for the Phoenix Cascade BIOS A20 control methods. Alternately, /CONTROLA20:OFF instructs HIMEM to not detect the control method for the A20 line and assumes the A20 line is always on. The /BIOS switch forces the use of BIOS Int15h, Function 87h, for data transfers to and from XMS memory. The /QUIET switch forces HIMEM to remove the sign-on message when loading.

E-EQ-MX2RG-L-ARC MX2 Reference Guide 88 ROM-DOS Commands

Error Conditions No Extended Memory—An extended memory error condition can occur if the BIOS (via Int 15H, function 88H) notifies HIMEM that there is no extended memory. In this situation, HIMEM displays an appropriate error message and does not install. Failure to Control the A20 Line—When HIMEM installs, it attempts to control the A20 line, which controls access to the HMA. HIMEM first attempts control via the AT method (using the 8259 keyboard control). If that fails, HIMEM then attempts control via the PS/2 method (using I/O port 60H). If both methods fail, HIMEM assumes it can’t control the A20 line and displays the message A20 Control (OFF) If either of these errors occur, try using the /A20, /A20+, or /PS2 in the HIMEM command line. Note also that some older programs assume that the machine is a 1MB 8086 and so require that the A20 line to be disabled (OFF) while they run. Current programs typically do not require that the A20 line be disabled.

Examples Device = HIMEM.SYS Installs the XMS device driver. Once this driver is installed, accessing the HMA and Extended Memory (XMS) memory areas are legal. The Extended Memory area can contain up to 2GB of memory. Typical systems have 4, 8, or 16MB of XMS memory installed. Device = HIMEM.SYS /machine:1 Forces the use of the AT-style A20 line control. The HIMEM driver fails to load when either the machine does not have memory above the 1MB boundary or the BIOS does not provide support for it. It also fails to load when another XMS manager has been previously installed.

MEM.EXE

External Command The MEM command displays the used and free memory in your system.

Syntax MEM [/BiosExtensions] [/Classify] [/Raw]

Remarks /B Displays each BIOS extension and its size. /C Classifies the memory usage. /R Does raw dump of the MCB chain. MEM displays a list of the DOS memory contents, what free space is available, and how much memory is in conventional memory, upper memory, the HMA and extended memory. This program is useful to fine tune the system to have as much free memory as possible for applications.

Options The /B option displays BIOS extensions in the range from C000:0 to F800:0. The /C option shows program, TSR, and device driver sizes. The /R option shows a low-level DOS listing of MCBs (Memory Control Blocks).

MODE.COM

External Command The MODE command modifies the operation of the printer, serial port, and active video display.

Syntax MODE LPT#[:]=COM#[:] MODE COM#:baud[,parity[,databits[,stopbits[,P]]]] MODE

Remarks The first syntax above redirects line printer output to the serial port. The second syntax above changes the operation of the specified communications port. The options that can be modified are listed below. InValid for any of the options are flagged with an error message. baud 110, 150, 300, 600, 1200, 2400, 4800, 9600 parity N - None, O - Odd, E - Even databits Either 7 or 8 stopbits Either 1 or 2 stop bits P Printer Port Using the P option as the last argument causes output to be sent repeatedly to the printer port until successfully received. Without the P, output is sent only once, causing a critical error if unsuccessful. The third syntax changes the active video mode for the display terminal. The valid choices for this version of the MODE command are as follows: 40—Indicates 40 characters per line. 80—Indicates 80 characters per line. bw40—For a color graphics adapter with color disabled and 40 characters per line. bw80—For a color graphics adapter with color disabled and 80 characters per line. co40—Indicates a color monitor with color enabled and 40 characters per line. co80—Indicates a color monitor with color enabled and 80 characters per line. mono—For a monochrome display. Assumes 80 characters per line. The final syntax sets the number of display lines. Valid included L25, L43, and L50.

Note: A serial port should be initialized before an LPT device is redirected to it.

Examples MODE COM1:9600,n,8,1 Modifies the settings for the COM1 device to a baud rate of 9600, no parity, eight data bits, and one stop bit. MODE LPT2:=COM2 Redirects the output from LPT2 to the COM2 serial port. All following output to LPT2 actually goes to the COM2 device. MODE mono Indicates a monochrome display adapter.

MORE.COM

External Command The MORE command displays a text file one screen at a time.

Syntax MORE [filename] or | MORE

Remarks The input to MORE may come from a file, or it may be piped in from another filter or a DOS command. If the filename is present, then the file is viewed; otherwise MORE reads from the Standard Input. Once a screen has been viewed, a line is displayed on the bottom of the screen indicating the percent of the file that has been viewed. At this point, there are several options for the next lines of text to be viewed. B Display the previous full page. Display just one more line. T Display starting at the top of the file. Spacebar Display the next full page of text. Q Exit MORE

Examples DIR | MORE Displays a directory one screen at a time. MORE READ.ME Displays the file READ.ME one page at a time.

NED.EXE and NED.CFG

External Command ASCII text Editor Program The NED editor is a menu-based text editor available for use with ROM-DOS. This editor is similar to other desktop editors but has special functions designed for use in editing C-source and assembly code.

Starting the Editor To start the editor, enter NED [filename] [filename] NED may be initiated with or without filename arguments. Wildcard file specifications are allowed. Up to ten files can be entered on the command line. If NED is run without arguments, it loads all files accessed during the last editing session, returning you to the exact position in the file. You can switch between the open files. You can also enter NED @errfile where errfile is the name of your compiler error output file. NED loads all files that had errors and allows you to move between errors. Once NED is running, you may load files into memory by using the File/Open menu command. File/Reload replaces the current file with a new file or reloads a new copy of the same file. File/Reload confirms before replacing an unsaved file.

Basic Editor Operation NED uses the standard Microsoft Windows interface for cut, copy, and paste operations. Del and Shift+Del both move the selected block to the clipboard. There is no true undo command, but Ctrl+V or Shift+Ins may be used to paste the clipboard contents to the current cursor position. Table 1 lists all the default shortcut keys. If a search string is all lowercase, NED treats it as a case-insensitive search. If a search string contains any uppercase letters, it is case sensitive. The replacement string is inserted exactly as entered. Repeating a Search command repeats the last Forward or Backward Search operation, not the last Replace operation. There is one bookmark for all files. Once the bookmark is set, going to the bookmark returns you to the file and position where you set it. The Indent and Remove-indent (referred to as Undent in the Options/Do Command) commands work on tabs. Indent inserts a tab at the beginning of the current line, or if a block is active, at the beginning of each line in the block. Remove-indent removes the first tab from the current line or from each line in the block. If there are no tabs, Remove-indent has no effect. Toggle case inverts the case of the current character if no block is active. If a block is active, Toggle case sets the entire block to uppercase if the first character was lower and to lowercase if the first character was uppercase. Tabs are currently set to 3 for .C, .H, .CPP, .HPP, and .T files. They are set to 8 for all other files. File/Print prints the current block if there is one, otherwise it prints the current file. NED prompts for a device to print to, which may be a filename. Tabs are expanded to spaces.

MX2 Reference Guide E-EQ-MX2RG-L-ARC ROM-DOS Commands 93

The Options/Do Command is intended primarily for debugging. This command allows you to execute any editor command by choosing it from a menu list. The macro commands (Record Macro/Play Macro) allow you to define a sequence of keystrokes that can be repeated repetitively. Select Record Macro (ALT=), enter the keystrokes, then press ALT= again. The macro sequence can be played by selecting Play Macro or by pressing ALT-. Keyboard bindings are saved in NED.CFG in the same directory as NED.EXE. NED.CFG also contains the list of active files and positions. If you record and play a recursive macro, it plays continuously. If you press an invalid key on a menu, NED operates as if you pressed enter. If you run out of memory, such as when you have more than 300KB of files open, NED returns to DOS.

NED Default Hot Keys Many of the editor commands can be accessed directly by pressing key combinations. For example, press Alt-X to exit the editor and save any open files. The following table lists the default hot keys. Key Function Key Function Alt-Q Quit without saving F1 Help Alt-X Exit, saving as needed F7 Load file into current buffer Ctrl-A Search again F9 Save file Ctrl-B Search backward F10 Exit asking for save as needed Ctrl-C Copy the block to clipboard Left-Arrow Left one character Ctrl-D Find the mark Right-Arrow Right one character Ctrl-E Erase to end-of-line Up arrow Up one line Ctrl-F Search forward Down arrow Down one line Ctrl-G Go to a line number Home Beginning of line Ctrl-I Indent the block End End of line Ctrl-K Toggle block mode Page Up Up one screen Ctrl-L Delete line to the clipboard Page Down Down one screen Ctrl-M Set the mark Center (5) Center the cursor onscreen Ctrl-N Read a file into a new buffer Ctrl-Left-Arrow Left one word Ctrl-P Move to the previous position Ctrl-Right-Arrow Right one word Ctrl-Q Quote the next character Ctrl-Up-Arrow Up one C function Ctrl-R Replace text Ctrl-Down-Arrow Down one C function Ctrl-S Switch to the next buffer Ctrl-Home Scroll toward beginning of file Ctrl-T Toggle the case of character(s) Ctrl-End Scroll toward end of file Ctrl-U Remove indent from the block Ctrl-Page Up Beginning of file Ctrl-V Insert the clipboard Ctrl-Page Down End of file Ctrl-W Delete word to the clipboard Ins Toggle Insert/Overwrite mode Ctrl-X Delete block to the clipboard Del Delete character Ctrl-Z Cancel the selected block Backspace Delete character backward Alt = Start/end recording macro Ctrl-Ins Copy block to clipboard.

E-EQ-MX2RG-L-ARC MX2 Reference Guide 94 ROM-DOS Commands

PRINT.COM

External Command The PRINT command prints a single file or a list of files.

Syntax PRINT [/drive:] [filename] [/options]

Remarks PRINT allows you to enter between one and 32 files for spooling to the printer. The files are output to the device in a spooled manner (while you perform other operations). If PRINT is entered without any parameters, it displays all the files that are in the queue. The first time PRINT is used, the user is prompted with this message for the device to perform the operation. Name of list device [PRN]: The legal devices for printing are LPT1, LPT2, LPT3, LPT4, COM1, COM2, COM3, COM4, AUX, or PRN.

Options The /B option sets the buffer size. The default buffer size is 512 bytes. A larger buffer size causes print to operate faster. The maximum buffer size is 32KB and the minimum size is 256 bytes. This option is only allowed the first time PRINT is run. The /C option cancels only the filenames listed after the /C command. The /F option sets the maximum number of files to be queued up at one time. The default number of files is ten. The minimum is two and the maximum is 32. Support for more files is often useful when using wildcards in filenames. This option is only allowed the first time PRINT is run (or until the next system reboot). The /P option causes all files listed after this option to be submitted for printing. This is the default for filenames encountered on the PRINT command line. The /T option cancels all the files from the print queue (list). The /H option displays the help screen.

Examples PRINT FILE1.TXT FILE2.TXT FILE3.TXT Puts three files into the print queue. The first file prints after the command ends. PRINT /C FILE2.TXT Removes file FILE2.TXT from the print queue. All other files in the queue print normally. PRINT /T Cancels all files in the print queue. Printing may continue for a short time because of the buffer in your printer.

MX2 Reference Guide E-EQ-MX2RG-L-ARC ROM-DOS Commands 95

REMDISK.EXE

Remote Disk Program See Also: REMSERV.EXE REMSERV is usually run on the MX2 (host). REMDISK is usually run on the client (e.g. a desktop PC). The remote disk program allows you to access a disk drive on a remote system via a serial cable and standard PC-style (8250UART) serial port. In a remote disk setup, one system, the one that shares its drives, is termed the server. The other system, the one that accesses and uses the remote drives, is called the client. The serial ports on both systems must be connected via a null modem cable. Remdisk / Remserv works across a standard 3-pin serial cable. The cable does not require the CTS/RTS DTS/DTR pins. To use the remote disk, both REMDISK and REMSERV must be running on their respective systems and must use the same baud rate and packet or nonpacket-style transmission. After starting both programs, you can access the new drive on the client system. You can change the default directory to this new drive, copy files to and from the remote drive, and also run utilities such as CHKDSK on the drive. The remote drive on the server system can be used as any other drive on the client system.

Syntax The program REMDISK runs on the client system and creates a new drive letter for the client. REMDISK uses the next available system drive letter. For example, if the last assigned drive was D:, REMDISK creates drive E:. This drive acts like any other drive, except that it requires the serial port. REMDISK.EXE can be loaded by a DEVICE= command in the CONFIG.SYS or AUTOEXEC.BAT files or it can be entered at the DOS prompt. CONFIG.SYS –-- DEVICE=REMDISK.EXE /T15 AUTOEXEC.BAT – REMDISK /B9600 / COM2 /T10 The syntax for REMDISK is: REMDISK [/U] [/H] [/Bnnnn] [+|-][/Tnnn] [/COMn] The default is: /B115K+ /COM1 /T3

Option Description

/U Unloads REMDISK from memory, thereby disabling the drive letter and freeing the memory occupied by REMDISK. This option can only be used when REMDISK is installed from the DOS command line. A remote disk installed via CONFIG.SYS cannot be unloaded.

/H Selects hardware handshaking for flow control.

/Bnnnn Selects the baud rate for transmission. Available baud rates are 300, 1200, 2400, 4800, 9600, 19200, 38400, 57600, and 115000. The default baud rate is 115000.

+/- The plus sign (+) specifies packet-style transmission and is recommended for any baud rate over 19200. The default setting is to include + for packet transmission. Use the minus sign (-) to specify polling operation under Microsoft Windows 95. Both sides must agree on using either (+) or (-).

E-EQ-MX2RG-L-ARC MX2 Reference Guide 96 ROM-DOS Commands

Option Description

/Tnnn Sets the time-out in the range of 3 to 3,640 seconds. 15 seconds is not unusual for Flash drives.

/IRQn Set the IRQ for the communications port. Valid settings are 3 – 15. Default is IRQ3 for COM 2 and COM4, and IRQ4 for COM1 and COM3.

COMn Selects the communication port. Choose 1, 2, 3 or 4. COM1 is the default port.

To install the REMDISK program from CONFIG.SYS at 19200 baud, on COM1, using packet- style transmission, insert the following line in CONFIG.SYS and then reboot the system (remember to include the full path to find REMDISK.EXE if not located in the root directory). DEVICE=REMDISK.EXE /B19200 + To display a help screen for REMDISK from the DOS prompt, enter REMDISK /? To install REMDISK from the DOS prompt or from a batch file (such as AUTOEXEC.BAT) at 9600 baud, without packet-style transmission, on COM2, enter REMDISK /B9600 /COM2 To unload the REMDISK installed from the batch file or the DOS prompt, enter REMDISK /U

REMSERV.EXE

Remote Disk Program See Also: REMDISK.EXE REMSERV is usually run on the MX2 (host). REMDISK is usually run on the client (e.g. a desktop PC). The remote disk program allows you to access a disk drive on a remote system via a serial cable and standard PC-style (8250UART) serial port. In a remote disk setup, one system, the one that shares its drives, is termed the server. The other system, the one that accesses and uses the remote drives, is called the client. The serial ports on both systems must be connected via a null modem cable. Remdisk / Remserv works across a standard 3-pin serial cable. The cable does not require the CTS/RTS DTS/DTR pins. To use the remote disk, both REMDISK and REMSERV must be running on their respective systems and must use the same baud rate and packet or nonpacket-style transmission. After starting both programs, you can access the new drive on the client system. You can change the default directory to this new drive, copy files to and from the remote drive, and also run utilities such as CHKDSK on the drive. The remote drive on the server system can be used as any other drive on the client system. The server system runs the program REMSERV.EXE that can make a single drive on the server system available to the client. The available drive can be changed at any time by quitting the REMSERV program and then running the program again with a new drive letter. The server program can be terminated at any time by pressing the Esc key. The client can then no longer access the server’s drive until the REMSERV program is run again.

MX2 Reference Guide E-EQ-MX2RG-L-ARC ROM-DOS Commands 97

Syntax REMSERV.EXE d: [/Tnnnn] [/H] [/Bnnnn][+|-] [/COMn] [/IRQn] [/Tnnn] [/S] where d: represents the letter of the drive the server makes available to the client. The default is /B115+ /COM1 /T2

Option Description

/Bnnnn Selects the baud rate for transmission. Available baud rates are 300, 1200, 2400, 4800, 9600, 19200, 38400, 57600, and 115000. The default baud rate is 115000.

+/- The plus sign (+) after the BAUD specifies packet-style transmission and is recommended for any baud rate over 19200. The default setting is to include + for packet transmission. Use the minus sign (-) to specify polling operation under Microsoft Windows 95. By default, packet transfers will be used for all baud rates higher than 9600. Both sides must agree on using either (+) or (-).

COMn Selects the communication port. Available ports are 1, 2, 3 or 4. COM1 is the default port.

/IRQn Set the IRQ for the communications port. Valid settings are 3 – 15. Default is IRQ3 for COM 2 and COM4, and IRQ4 for COM1 and COM3.

/Tnnn Sets the time-out in the range of 2 to 3,640 seconds. 15 seconds is not unusual for Flash drives.

/S Instructs REMSERV to run without any display output (Silent).

/H Selects hardware handshaking for flow control.

Example To select drive B: as the available server drive at 115000 baud, packet transmission, using COM1, enter REMSERV B: To set drive C: as the server disk at 38400 baud, without packet-style transmission, on COM2, with a timeout of 10 seconds, enter: REMSERV C: /B38400 /COM2 /T10

E-EQ-MX2RG-L-ARC MX2 Reference Guide 98 ROM-DOS Commands

SYS.COM

External Command The SYS command copies the ROM-DOS system files ROM-DOS.SYS and COMMAND.COM from the disk in the default drive to the disk in the specified drive. The file ROM-DOS.SYS is renamed and stored on the disk as files IBMBIO.COM and IBMDOS.COM, which are stored as hidden files.

Syntax SYS drive: [/options]

Remarks Use the SYS command to transfer the ROM-DOS system files to a floppy disk or hard disk. The disk can be a formatted blank disk or can contain files; it is not necessary for the system files to be the first files on the disk. The only requirement is that there is enough contiguous free space on the disk for the new system files to be placed. If the disk already contains system files, installing the new system files deletes the existing files. The command processor, COMMAND.COM, is also transferred to the disk and does not need to be copied into the same contiguous space as the system files. You can run SYS three different ways. The first is to boot and run your system with ROM-DOS. When you run the SYS command this way, SYS copies the ROM-DOS system files and COMMAND.COM from the root directory of the default/current disk drive. The second method is to run SYS from the root directory of a disk drive that has been previously prepared with the SYS command, but isn’t booted and running. For example, you can run SYS from a bootable floppy disk to copy the files to the hard disk without actually booting from the floppy disk itself. The third method uses the file ROM-DOS.SYS, the equivalent of the hidden system files IBMBIO.COM and IBMDOS.COM. ROM-DOS.SYS should be present in the same directory with COMMAND.COM and SYS.COM. These three files can be placed in the root directory or subdirectory on a floppy disk (that need not be booted or bootable), or in a subdirectory on the hard drive. Run the SYS command from the directory where the files reside to transfer the system files to the destination drive.

Options The /C option prevents confirmation before transferring system files. The /H option shows the newly transferred system files on the destination disk. The /] option prevents display of the sign-on message.

Example SYS B: Copies the ROM-DOS system files to drive B:.

MX2 Reference Guide E-EQ-MX2RG-L-ARC ROM-DOS Commands 99

VER

Type Internal

Purpose Displays the version number of ROM-DOS in use. Allows revision of this version number.

Syntax VER [n.nn] [/R]

Remarks If a new version number is specified, two digits after the decimal are required. Note that this command revises only the record of the DOS version number; it does not change the actual operating system loaded in the computer. The version command shows both the version of the VER command itself and the version of DOS in operation.

Options The /R option shows the full version and release number of ROM-DOS.

Example The following example changes the record of current DOS version in use to DOS 5.0. Any programs that are executed, following this command, will recognize that DOS 5.0 is running. VER 5.0

XCOPY.COM

External Command The XCOPY command copies multiple files and, optionally, subdirectories from one disk to another.

Syntax XCOPY [source] [target] [/options]

Remarks Use the XCOPY command to copy multiple files and subdirectories, if they exist. The source and the target parameter are complete drive-path and file-specification descriptions. If you do not specify a path, XCOPY assumes the default path. If a filename is not specified, then *.* is assumed. The ATTRIB command may be used to modify the archive bit for the various XCOPY options that check the archive status of files. Refer to the ATTRIB command for instructions.

E-EQ-MX2RG-L-ARC MX2 Reference Guide 100 ROM-DOS Commands

Options The /A option copies only source files that have the archive bit set in them. The archive is not reset. The /D option copies only those files with a date later than that specified. The /E option creates subdirectories on the target even if they are empty. The /M option copies only those source files that have the archive bit set. Once the source file is copied, the archive bit is reset. The /P option prompts before each file is copied. The prompt appears as follows; enter Y to copy the file: C:\COMMAND.COM (Y/N)? The /S option copies files in subdirectories of the source directory. The /V option verifies each write to the disk. The /W option waits before starting to copy files and prompts with the following message. Press any key to begin copying file(s)

Example XCOPY \bin\*.exe a: /a Copies all files in the BIN subdirectory to the A: drive that have an .EXE extension and that have the archive bit set.

Chapter 5 The Docking Station

Introduction

LXE offers one docking station for the MX2 – a stationary single dock that holds one MX2. The stationary single dock powered docking station has two primary uses: • Recharge the MX2 NiMH battery pack and lithium backup batteries. • Provide a connection for serial communications between the MX2 and the host computer or another serial device, such as a printer or modem. The powered docking station requires an AC/DC power source.

Note: Do not use the MX2 docking station with any other unit. Note: The MX2 is not designed to use alkaline batteries.

Please refer to the “MX2 User’s Guide” when using the MX2 with a Docking Station.

You can use a 9-volt power adapter with the Single Dock to recharge the batteries in the MX2. Power adapters are available from LXE. Attach the small, round plug of the power adapter to the power input jack on the back of the Single Dock. Plug the other end into an AC outlet or power strip. The red light-emitting diode (LED) labeled POWER on the front panel of the Single Dock should light up. The power adapter is used only to recharge the batteries in the MX2. However, if you do not use it, the LED indicators on the Single Dock will not light up. (The READY light indicates that the MX2 is properly inserted in the dock. The READY light will appear red when charging MX2 batteries and green when batteries are fully charged.)

Note: Use only a 9-volt power adapter supplied by LXE. Using another adapter can damage the dock.

MX2 Reference Guide E-EQ-MX2RG-L-ARC The Single Dock 107

Using a Single Dock Set up the Single Dock as described in the preceding sections. Place the MX2 into the dock, with the keypad facing the front. If you are using a power adapter, the green LED labeled READY on the front panel of the Single Dock should light up.

Note: If the READY light does not come on, make sure the POWER light is on and the MX2 is fully inserted into the dock, with the keypad facing out. If it still doesn’t work, make sure the power adapter is securely attached to the MX2 and that the contacts in the dock are clean. (If you are not using a power adapter, the light will not come on.) While the MX2 is in the Single Dock, you can download programs to it or upload data from it just as if it were connected directly to your computer. If you are using a nickel metal hydride (NiMH) battery pack in the MX2, you can use the Single Dock to recharge the batteries. Simply leave the battery pack in the MX2 when you place it in the dock. The battery pack and the lithium backup battery will be recharged while the READY light is on. The charging time is 3 to 8 hours, depending on the type of battery pack and the current charging level.

Charging Batteries To charge the rechargeable batteries in a MX2, place the MX2 into a dock that is connected to a power supply. The dock does not need to be connected to a computer.

Transferring Files You can transfer files with the REMDISK and REMSERV utilities. For more information on these utilities, please refer to Chapter 4, “Commands”.

Appendix A Connector Configurations

Introduction

Cables for all MX2 products are available from LXE. However, you may want to make your own cables for custom uses. This appendix provides information about MX2 cables, including diagrams and tables describing the connector configurations for the MX2 and the Single Dock.

The MX2 Computer Serial IR Port The IR port provides an IR transceiver for sending and receiving half-duplex IR data that meets the IrDA physical layer specifications. In addition, thee are three pads along the bottom of the unit. The pads are used when the MX2 is in the dock. With the MX2 oriented with it’s keypad facing toward the user: The right-most pad is the positive lead and is used for recharging the MX2 batteries. The center pad is the negative lead and is used for recharging the MX2 batteries. The left-most pad is used for modified RS-232 input into the MX2. This pin serves as RXD while the MX2 is in the dock.
