Backing up the Disk
The software provided with the IDO-xx series are supplied on DOS formatted diskettes. As with any software package, you should make backup copies for everyday use and place your original master diskette in a safe location.
The easiest way to make a backup copy is to use the DOS DISKCOPY utility.
In a single-drive system the command is:
DISKCOPY A: A:
In a two-disk system the command is:
DISKCOPY A: B:
This will copy the contents of the master disk in drive A to the backup disk in drive B.
Hard Disk Installation
The files contained on the master diskette may also be copied onto your hard disk. To do this perform the following:
1. Place the master diskette into a floppy drive. 2. Change the active drive to the drive that has the master diskette installed. For example, if the diskette is the A drive, type A: 3. Type INSTALL and follow the screen prompts.
Files contained on the disk are stored in separate directories as follows:
ROOT DIRECTORY: Contains the FINDBASE PROGRAM that will help you to decide what base address to use with the card. Also contains the IDO48SET.EXE setup program. PSAMPLES: Contains Pascal sample. CSAMPLES: Contains C sample. BSAMPLES: Contains QuickBASIC sample. VBACCES: VisualBASIC utility driver that includes PEEK and POKE statements for reading and writing RAM as well as OUTPORT and INPORT for reading and writing port I/O. The driver is in the form of a DLL and allows you to access hardware as if the language was designed for it when you use VisualBASIC for Windows.
Manual Number: 00650-017-1 Page 1-1 IDO Series Manual
Installing the Card
Before installing the card carefully read the ADDRESS SELECTION and OPTION SELECTION Sections of this manual and configure the card according to your requirements. Use the special software program called IDO48SET provided on diskette with the card. It supplies visual aids to configure all areas of the board.
Be especially careful with address selection. If the addresses of two installed functions overlap, you will experience unpredictable computer behavior. If unsure what locations are available, you can use the FINDBASE program provided on our diskette to locate blocks of available addresses.
To install the card:
1. Remove power from the computer. 2. Remove the computer cover. 3. Remove blank I/O backplate. 4. Install jumpers for selected options. See OPTION SELECTION 5. Select the base address on the card. See ADDRESS SELECTION 6. Loosen the nuts on the strain relief bar and swing top end free
CAUTION!
This card can be used with signals that contain very high common mode voltages. For safety, the cables should not be connected to the sources of these signals when installing or removing connections to the card. Further, to assure that the cables arent pinched by the strain relief bar, it is good safety practice to enclose the cables in a protective jacket.
7. Install the card in an I/O expansion slot. If convenient, select a slot adjacent to a vacant slot because this will make cable installation easier. 8. Thread the I/O cables, one by one, through the cutout in the mounting bracket and plug them into the headers. 9. Smooth the cables as close as possible to the card and, while holding them close to the surface of the card, swing the strain relief bar into position and tighten nuts. 10. Inspect for proper fit of the card and cables and tighten screws. 11. Replace the computer cover.
Input/Output connections are via 50-pin header(s) on the card. A blank mounting bracket is pro- vided with units marked for CE (European) Certification and, for these units, CE- certifiable cable and break-out methodology (cables connected to ground at the aperature, twisted pair wiring, etc.) must be used. Also, it is important that the card mounting bracket be properly screwed into place and that there be a positive chassis ground.

Features
Individually-Isolated Digital Outputs for up to Three 16-Bit Groups. All solid-state design permits higher throughput than possible with electromechanical relays. Load voltages up to 60 Volts. On-Card shields prevent accidental contact with user voltages. Outputs at zero volts at power turn-on and computer reset. Output connectors via on-card ribbon-cable headers. Lower cost per point than externally-racked solid-state relay modules.
Description
IDO-xx Series cards provide 16, 32, or 48 opto-isolated differential outputs and plug into expan- sion slots of IBM PC/XT/AT or compatible computers. Solid-state, P-Channel FET switches are used as the output elements and provide both greater reliability and much faster turn-on and turn- off time than is possible with electromechanical relays. User-supplied load voltages can be from 5V to 60V. Output connections are via 50-wire ribbon cables that mate with headers on the card. A strain relief bar where the cables exit the card assures that the cables will not interfere with adja- cent cards. Standard cables are six feet long but alternate lengths are available. Model UTB Screw Terminal Accessory cards, one per each 16 bits, can be used to provide easy connection to your system.
The card uses six bytes of I/O Bus address; one byte for each eight bits of output. Outputs of a programmable array logic chip enable data bytes to be clocked into latches. Outputs of the latches, in turn, are connected via opto-couplers to the output P-channel FET drivers. The opto-couplers used are rated to 5 KV and on-card isolation channel-to-channel and channel-to-computer exceeds 500 Vrms. (Note: Ribbon cables typically provide 300 Vrms isolation.) The P-Channel FET drivers are capable of 1 Ampere steady-state current (Note: Current output may be limited by the cable to as little as 0.5A). Diodes are included across the load for inductive-spike protection.
There are 48-bit, 32-bit, and 16-bit versions. The latter two models are de-populated versions of the 48-bit card.

Figure 1: IDO48 Block Diagram
Each bit controls a single power FET to switch an externally supplied voltage between the supply pin and the return as illustrated by the example circuit below:
Each bit of the IDO card is optically-isolated from the output driver which switches the supply voltage to the output pin. The negative connection is made on the return pin and each output is isolated from every other output.
When the opto-isolator is ON, the FET is activated by the Zener-diode-limited supply voltage. When the FET is ON, the full Supply voltage is available at the output pin. When the opto-isolator is deactivated, the FET opens and the output drops to the return line voltage level.
The opto-couplers used are rated to 5 KV and on-card isolation channel-to-channel and channel-to- computer exceeds 500 Vrms. (Note: Ribbon cables typically provide 300 Vrms isolation.) The P- Channel FET drivers are capable of 1 Ampere steady-state current (Note: Current output may be limited by the cable to as little as 0.5A). Diodes are included across the load for inductive-spike protection.

How to remain CE Compliant
In order for machines to remain CE compliant, only CE compliant parts may be used. To keep a chassis compliant it must contain only compliant cards, and for cards to remain compliant they must be used in compliant chassis. Any modifications made to the equipment may affect the CE compliance standards and should not be done unless approved in writing by Industrial Computer Source.
The IDO Series is designed to be CE Compliant when used in an CE compliant chassis. Maintain- ing CE Compliance also requires proper cabling and termination techniques. The user is advised to follow proper cabling techniques from sensor to interface to ensure a complete CE Compliant system. Industrial Computer Source does not offer engineering services for designing cabling or termination systems. Although Industrial Computer Source offers accessory cables and termina- tion panels, it is the user's responsibility to ensure they are installed with proper shielding to main- tain CE Compliance.
Manual Number: 00650-017-1 Page 2-3 Chapter 3: Address Selection Chapter 3: Address Selection
The IDO-48 card occupies eight bytes of I/O space. The card base address can be selected any- where within the I/O address range 100-3F0 hex except 1F0 to 1F8. However two installed options cannot share the same address. If in doubt where to assign the base address, refer to the following tables and the FINDBASE program to find an available address for your system.

To set desired board address , refer to the illustrated Board Address setup program on the Utility diskette provided with the card. Type the desired address in hexadecimal code and the graphic display shows you how to set the ADDRESS SETUP switches. These switches are marked A3-A9 and form a binary representation of the address in negative-true logic. (assign 0 to all ADDRESS SETUP switches turned ON, and assign 1 to all ADDRESS SETUP switches turned OFF.)

Software Provided
Several programs are supplied on diskette with your card. These are a setup program, a program to help you select an I/O bus address that wont conflict with other computer resources, a DLL-form program for Windows users, and three sample programs to help you develop your applications software. These programs are as follows:
* IDO48SET: This is a menu-driven, pictorial program to help you set the card address, interrupt level, change-of-state interrupt, and high level interrupt enable. * FINDBASE: Reports active and available address locations in your computer for assignment as the IDO card base address. * SAMPLE1.C: This program is a C-language software program. * SAMPLE1.PAS: This program is written for PASCAL applications. * SAMPLE1.BAS: This program is written for QuickBASIC applications. * VBACCES: A VisualBASIC utility driver that includes PEEK and POKE statements for reading and writing RAM as well as INPORT and OUTPORT for reading and writing I/O. The driver is in the form of a DLL and allows you to access hardware as if the language was designed for it when you use VisualBASIC for Windows.
VisualBasic Utility Driver
Extensions to the VisualBASIC language are on the diskette provided with your card. The exten- sions are in a directory named VBACCES. These extensions are in the form of a .DLL, a .GBL, and a VisualBASIC sample. Together these files allow you to access the port and main memory space in a fashion similar to BASIC, QuickBASIC, Pascal, C/C++, Assembly, and most other standard languages.
To use these files in a VisualBASIC program, you must create a .MAK file (File l New Project) similar to the sample provided (or else, modify your existing project file) and include the .GBL file (File | Add File). Once this has been done, VisualBASIC will be enhanced with the addition of the following functions.
InPortb
Function: Reads a byte from a hardware port. Due to limitations of VisualBASIC, the number is returned in an integer.
Declaration: function InPortb(byval address as integer) as integer
Manual Number: 00650-017-1 Page 4-1 IDO Series Manual
InPort
Function: Reads an integer from a hardware port. This function returns the 16-bit value obtained from reading the low byte from address and the high byte from address+1.
Declaration: function InPort(byval address as integer) as integer
OutPortb
Function: Writes the lower eight bits of value to the hardware port at address. This function returns the value output.
Declaration: function OutPortb(byval address as integer, byval value as integer) as integer
OutPort
Function: Writes all 16 bits of value to the hardware port at address. This function returns the value output.
Declaration: function OutPort(byval address as integer, byval value as integer) as integer
Peek
Function: Reads a byte from main memory (DRAM).
Declaration: function Peek(byval segment as integer, byval offset as integer) as integer
Poke
Function: Writes the lower eight bits of value to segment:offset. Declaration: function Poke(byval segment as integer, byval offset as integer, byval value as integer) as integer
Note that in all of the above functions, an inherent limitation of BASIC in general and VisualBASIC in particular makes the values sent less intuitive. All integers in BASIC are signed numbers, wherein data are stored in twos complement form. All bit patterns must be converted to-and-from this twos complement form if meaningful display is required. Otherwise, values returned from the InPortb function will be -128 to 127, rather than 0 to 255. An alternative is to perform all assign- ments in hexadecimal, rather then decimal form.
Before the program will execute, the .GBL file must be modified to include the path to the VBACCES.DLL as appropriate for your system. Merely replace the statement VBACCES.DLL with drive:path\VBACCES.DLL.
As an alternative to changing the source code, you can copy the VBACCES.DLL file into your Windows directory. This will allow multiple programs to find the same .DLL without having to know where it is located. Just leave off all references to a path in the .GBL file as shown in the sample.
Page 4-2 Manual Number: 00650-017-1 Chapter 5: Programming Chapter 5: Programming
IDO-Series cards are I/O-mapped devices that are easily configured from any language and any language can easily perform digital inputs through the cards ports. This is especially true if the form of the data is byte or word wide. All references to the I/O ports would be in absolute port addressing. However, a table could be used to convert the byte or word data ports to a logical reference.
A total of six address locations are used by the IDO-xx. Register locations are listed in the follow- ing table.

ADDENDUM
IRQGEN.VXD and Win32IRQ.DLL
IRQGEN.VXD Description IRQGEN.VXD is a Virtual Device Driver, or VxD, for Windows95. Together with Win32IRQ.DLL, it allows a program to easily respond to hardware interrupt requests, or IRQs.
Installation To install IRQGEN.VXD, copy it to C:\Windows\System. If your hard drive has a letter other than C, substitute the appropriate letter. It is not necessary to reboot your system prior to using IRQGEN.VXD.
Win32IRQ.DLL Description Win32IRQ.DLL is a Dynamic Link Library, of DLL, for Windows95. It provides a simple interface to IRQGEN.VXD, allowing a program to easily respond to hardware interrupts. Three functions are exported by Win32IRQ.DLL: InitIRQ,, Detect IRQ, and SendEOI. To use these functions in a program, they must first be inported. In Pascal, the necessary lines would be:
function InitIRQ (MyIRQ: Byte) : Boolean; stdcall;external 'Win32IRQ.dll' index 1; function DetectIRQ: Boolean; stdcall; external "Win32IRQ.dll"index 2; function SendEOI: Boolean; stdcall; external "Win32IRQ.dll" index 3;
In C, the library file Win32IRQ.lib must first be linked to the program. This is accomplished by adding it to the project or editing the makefile. The following lines would then create the prototypes for the DLL functions:
extern "c" _declspec (dllimport) bool pascal InitIRQ (unsigned char MyIRQ); extern "c" _declspec (dllimport) bool pascal DetectIRQ (void); extern "c" _declspec (dllimport) bool pascal SendEOI (void) ;
InitIRQ This function performs the initialization required to detect IRQs. It must be called before DetectIRQand SendEOI can be called, although calling those functions first will only cause them to return a value of FALSE. The function's sole parameter is an unsigned 8-bit value containing the IRQ number to monitor. The return result is TRUE if initialization was compledted successfully, FALSE if not.
Addendum: 00650-010-6B Page 1 © 1998, Industrial Computer Source, 6260 Sequence Drive, San Diego, CA 92121-2720. All rights reserved. DetectIRQ This function suspends the thread that it was called from and waits for an IRQ to occur on the IRQ number that was passed to InitIRQ. DetectIRQ will return immediately, however, if an IRQ occured anytime before the DetectIRQ call, as long as an IRQ number was initialized with InitIRQ. Otherwise, DetectIRQ will not return until an IRQ occurs. If the program needs to continue running while waithing for DetectIRQ, a separate thread should be spawned from which to call DetectIRQ. The return result is TRUE if an IRQ was successfully detected on the given IRQ number, FALSE if no IRQ was initialized before the call. There are no parameters.
SendEOI This function sends an end of interrupt message to the VxD. It must be called after an IRQ is detected of the interrupt will remain in the system. The return result is TRUE if the EOI message was successfully sent, FALSE if not. There are no parameters.
