2 ARC-EVB Description
The core of the ARC-EVB is an Atmel T89C51 CPU which contains 16 KB of FLASH memory to hold the provided test application (Modbus-over-ARCNET)—or the user’s firmware. The FLASH memory can also hold the Keil monitor, allowing it to work with the Keil compiler/debugger. The ARC-EVB also contains an SMSC COM20022 ARCNET controller (backward compatible with the COM20020) which can support data rates from 156 kbps to 10 Mbps using a 20 MHz crystal. This chip offers enhanced features over earlier generation chips. New features include command chaining, sequential access to internal RAM, duplicate Node ID detection and variable data rates up to 10 Mbps. An 8-bit DIP switch (S1) is provided as the input device and 8 associated LEDs report the state of each input. An additional 8 LEDs indicate the states of the output signals. LED 7 in each array is the MSB. Another 8-bit DIP switch (S2) is used for setting the ARCNET Node ID. Switch 8 is the MSB. The data rate is set by jumpers at jumper block J8. The ARC-EVB uses an HYC4000 transformer-coupled ARCNET transceiver. This provides balanced EIA-485 signaling so that either a straight-through or a crossover cable can be used. ARCNET fieldbus connections are provided by either a 3- terminal open-wire connector or an RJ-11 jack for standard twisted-pair cable. An extra RJ- 11 jack is provided for installing the modular terminator provided in the ARC-EVS. The extra jack can also be used for daisy- chaining a twisted-pair bus if the ARC-EVB is configured with more than one ARCNET adapter. Figure 2 — Evaluation Board Block Diagram

3 PCI22-485X NIM
3.1 Description The PCI22-485X is one of a family of Contemporary Controls network interface modules (NIMs), each serving to link a PCI bus compatible computer with the ARCNET local area network (LAN). Each model within the family is identified by a model number ending in a 3- or 4-character suffix. This suffix specifies a transceiver type which matches a particular type of cable. Because the capabilities of each transceiver differ, different models cannot occupy the same LAN segment. The PCI22-485X supports data rates from 1.25 Mbps to 10 Mbps and operates in a Windows environment with one of our null stack drivers. The driver directory on the CD-ROM provides a selection of null stack drivers from which to choose. This NIM incorporates the same ARCNET controller chip as used on the ARC-EVB. Bus contention problems are minimized since the interrupt level and I/O base address are assigned through Plug and Play. There is no requirement for wait-state arbitration. Two LEDs monitor network operation and bus access to the module. An external DIP switch allows node addresses to be easily reassigned without removing the module.
3.2 Hardware Installation The NIM can be installed in any PCI bus compatible computer bus. With power detached from the computer, remove the computer cover to expose the motherboard and expansion slots (connectors). Care should be taken when installing the card; both it and the exposed motherboard are sensitive to electrostatic discharge. To prevent inadvertent damage, touch the metal case of the internal power supply to discharge yourself then remove the card from its protective ESD package. Remove the backplate of the computer adjacent to the desired slot (connector). Then insert the card into this slot by applying an even downward pressure until it firmly seats in the connector. The card’s backplate can be fastened to the computer with the small screw used to attach the original backplate. Hardware installation is completed by replacing the computer’s cover.
3.3 Software Installation Unlike ISA bus computers, PCI bus computers usually have their resources assigned by the operating system. The PCI22-485X NIM requires one interrupt line and a 16 byte I/O range for the COM20022 ARCNET controller. Once the NIM is inserted and power applied to the computer, Windows will recognize the card and ask the user for the driver location. Point to the folder appropriate to the version of Windows being used. After loading is complete the driver will be active. The driver can be disabled from the Device Manager.
Contemporary Controls TD020200-0MA 8
3.4 Indicator Lights There are two LEDs located at the NIM’s backplate. The green LED indicates that the card is transmitting ARCNET traffic to the network. The yellow LED indicates that the card is being accessed from the host computer via its I/O address.
Figure 3 — PCI22-485X Indicator Lights and Node ID Switch
3.5 Node ID Switch Although not always needed, this NIM has a separate input port that reads an 8-bit DIP switch (SW1) located at the backplate. This switch is meant to serve as a Node ID switch, although it can serve as a general purpose switch if desired. The switch has no connection to the COM20022 controller chip. The most significant bit (MSB) is switch position 8, and the least significant bit (LSB) is switch position 1. A switch in the open position (off position or away from the printed circuit board) introduces a logic “1.” In the example below, the switch is set to hexadecimal address AF.
3.6 Fieldbus Connection The PCI22-485X NIM supports AC-coupled communication via its daughter board which has a fixed-bias network isolated by a pulse transformer. Unlike DC-coupled devices, bias adjustment is unneeded and wiring polarity is unimportant. Dual RJ-45 jacks and one three-position screw terminal connector are the options for attaching the field bus wiring. For convenience, a modular cable is provided for connecting the NIM to the ARC-EVB. Each end of the fieldbus wiring must have a proper value of termination resistance. The NIM provides two options to achieve proper termination: Onboard Termination: Install the E1 jumper on the daughter board to apply an onboard resistance across the twisted-pair. If the jumper is removed, no termination is applied. External Termination: If you wish to enable or disable termination without removing the NIM from the host computer, external termination can be used. In this case, remove jumper E1 and insert either the provided RJ-45 modular terminator in the unused RJ-45 jack or a 120 ohm 1/4 watt resistor across pins 1 and 2 on the screw terminal connector. NOTE: Terminating with a value less than 100 ohms will excessively load the EIA-485 transceivers—so you must only use one method of termination at a time. If more ARCNET devices are attached to the NIM and the ARC-EVB in a bus topology, only apply termination to the devices located at the ends of the bus.

4 Source Code
The ARC-EVB is provided with Modbus-over-ARCNET example code for both server and client. When the server example code is executed on the ARC-EVB, it can receive one byte of output data and can transmit one byte of input data when polled by the Modbus client. The 8 LEDs on the ARC-EVB are used to indicate the received output data. The 8-bit DIP switch (S1) is used to provide ARC-EVB input data. The client software executes on a PC in which our PCI22-485X has been installed and requires the version of our Null Stack driver appropriate to the version of Windows being used. The Modbus client will continually request current Modbus data from the Modbus server (ARC-EVB) and will also update server output data when modified by the user. The ARCNET Control Panel is illustrated in Figure 4. The server application causes the current ARC-EVB input data to be displayed in the LED Status section of the panel and can change the ARC-EVB output data in the LED control section of the panel. The 8 output LEDs on the ARC- EVB are used to display its output state. Also included is a Keil monitor HEX file that (when copied to the ARC-EVB) allows the ARC- EVB to communicate with the Keil debugger. The HEX file for the Modbus-over-ARCNET server is also provided. This allows the user to switch between debugging with the Keil compiler and executing the Modbus-over-ARCNET server. Updated versions of Modbus-over-ARCNET client and server can be downloaded from www.ccontrols.com.

5 Modbus-over-ARCNET Setup
Confirm that the PCI22-485X NIM has been properly installed in the host computer (as per Sections 3.2 and 3.3) and that the ARC-EVB EEPROM contains the Modbus hex file. The ARC-EVB has been factory programmed with the Modbus firmware—so loading this firmware will only be needed if it has been erased. (See Section 7 for firmware modification).
PCI22-485X NIM Setup:
• Set the NIM’s Node ID switch to the desired value (1–255, decimal) as per Section 3.5. Optionally, the Node ID can be set via the Windows Application below. • Make sure the NIM has proper cable termination applied as per Section 3.6.
ARC-EVB Setup:
NOTE: The ARC-EVB will initialize with Data Rate and Node ID values existing during power up. Changes to these parameters will have no effect unless power is recycled.
• Set the Data Rate jumpers (J8) to the desired data rate as per Table 4 — Data Rate (J8). • Set the Node ID DIP switch (S2) to a Node ID that differs from that set on the NIM. • Install jumper JP1 to invoke onboard fieldbus termination. Optionally, the provided RJ-11 modular terminator may be inserted in the unused RJ-11 jack. • Apply power.
Fieldbus Setup:
• Connect the NIM to the ARC-EVB with the provided modular cable. Optionally, any CAT-5 twisted-pair cable may be attached between the open-wire connectors.
Contemporary Controls TD020200-0MA 11
Windows Application Setup:
• Launching the application will display the Control Panel in Figure 4. Until the Settings Panel options have been entered, the Control Panel features will remain inactive.
Figure 4 — ARC-EVB Control Panel — Inactive
• Selecting the Settings menu item will display the Settings Panel in Figure 5.
Figure 5 — Application Settings
• In the Node ID box enter the ARCNET Node ID to be associated with the NIM (and its host computer). A zero value causes the Node ID to be read from the NIM’s DIP switch. • The Board Number field specifies how many ARCNET NIMS are installed in the host computer. The default value of “1” rarely needs changing. If more Contemporary Controls PCI-based NIMS are installed, enter that number. • In the Data Rate box select the data rate which matches that set on the ARC-EVB.
Contemporary Controls TD020200-0MA 12
After completing the settings, the Control Panel will appear as in Figure 6. Three fields are “dimmed” because they are read-only — Read Status, Control Status and Number of Recons.
Figure 6 — ARC-EVB Control Panel — Active
• Enter a hex value for the Destination Node ID which agrees with the DIP switch value set on the ARC-EVB. This value must differ from the ID value set for the NIM. • The application is now ready for operation.
Contemporary Controls TD020200-0MA 13
6 Modbus-over-ARCNET Operation
When the ARC-EVB and the Windows application have achieved proper communications, the Control Panel will affect operation as follows.
Reading LED Status from the ARC-EVB Clicking the Start Button, will initiate the transmission of Modbus Function 3H Query Messages (see Section 10.1). The application will continually read information from the Input DIP switch (S1) on the ARC-EVB. Each time the read action is successful, the message “RX OK!” will appear in the Read Status field. As long as the ARC- EVB is working, each change to the Input DIP switch will instantly appear in the LED Status area of the Control Panel. Turning a switch “On” lights its associated LED on the ARC-EVB and causes its associated LED icon in the Control Panel to glow red. In the example shown in Figure 7, switches 4-7 have been turned on. Figure 7 — LED Status While the Start Button is dim, changing the value in the Destination ID field will have no effect on the read action. Clicking the Stop Button concludes the read action, but the last data read continues to display. The next time the Start Button is clicked, the read function will use the current value in the Destination ID field — but the read action will not be successful unless this new value matches the Node ID value with which the ARC-EVB was initialized.
Controlling LEDs on the ARC-EVB Changes in LED Control will affect the Output LEDs on the ARC-EVB. LED Control has 8 checkboxes. Each time a checkbox is clicked, two things are determined — the Destination ID and the status of all 8 checkboxes. The checkbox data are transmitted via a Modbus Function 10H Query Message (see Section 10.1) to activate the corresponding LEDs on the ARC-EVB. But the transmission will fail unless the Destination ID matches the Node ID with which the ARC-EVB was initialized. Figure 8 — LED Control Figure 8 shows a query to activate LEDs 0 and 2 has been successfully sent to Node ID 1. The Control Status message “RX OK!” only means that a properly formatted query and response were exchanged. It does not confirm that the correct data arrived at the destination.
Number of Recons Network reconfigurations are counted in this field. The count can be reset to zero only by restarting the application. Contemporary Controls TD020200-0MA 14
7 Firmware Modification
The Atmel Flip application included on the CD-ROM is used to modify the ARC-EVB firmware. The application includes detailed online help, but a procedural overview is presented below.
Procedure: 1. Connect the ARC-EVB to a PC via the provided null-modem cable. 2. On the ARC-EVB, install the J1 jumper to enable firmware modification. 3. Apply power to the ARC-EVB. 4. Launch the Atmel Flip application.

Contemporary Controls TD020200-0MA 16
10. If the ARC-EVB is working and the signal path between it and the PC is proper, the device-specific panel will be updated with data read from the T89C51RB2 as shown in the example of Figure 12. (If communication between the Flip application and the ARC-EVB is improper, a Time Out Error will occur — check the ARC-EVB and the fieldbus cable.) Leave the upper portion of this panel alone, but make sure (as shown in Figure 12) that these adjustments are set in the lower portions of the panel:
• De-select X2 Mode
• Set Device SBV (Software Boot Vector) to FC
• Set the Device SSB (Software Security Byte) to FF
Figure 12 — Device-Specific Panel after Reading the T89C51RB2
11. To copy a new program to the ARC-EVB … • Select the menu item File > Load HEX … and open the desired file. The filename and size will be verified in the lower center area of the Flip window. • Under the Operations Flow panel on the left of the Flip window, check these boxes — Erase, Blank Check, Program and Verify • Click Run. The checked Operations Flow options should appear green, if successful.
When finished, close the Flip application, remove power from the ARC-EVB and remove jumper J1. The next time you power up the board, it should execute the new firmware.

The Modbus-over-ARCNET server can be debugged on the ARC-EVB using the Keil Debugger. Detailed built-in help screens are included with the Keil Compiler/Debugger, but a helpful general overview of using the Keil tools is presented below:
• Set the PC serial port to a baud rate of 19200. • Copy the entire Modbus-over-ARCNET server folder to your computer. * • Use Atmel Flip to copy the Keil monitor from the MON51 directory to the ARC-EVB. • Remove the J1 jumper from the ARC-EVB. • Recycle power to the ARC-EVB. • Start the Keil compiler. • Using the Project > Open Project menu option, open arc_eval.uv2.
• In the Select Target box, choose Debug Image.
• Use the Project > Rebuild all target files option to compile, link and build the project. • With the Debug > Start/Stop Debug Session option, load the target to the ARC-EVB.
• When the download is completed, enter $=0x8000 in the Command Line Window to set the program counter to 0x8000.
• Use the debugging options under the Debug menu to single step, set breakpoints or run the application. When the debugging is finished, terminate the debug activity with the menu option Debug > Start/Stop Debug Session. The final firmware to be written to the board is in target Flash Image. Use the Project > Rebuild all target files option to rebuild the flash image and generate a hex file called arc_flash.hex. Use the Atmel Flip application to copy the hex file to the ARC-EVB.
* NOTE: When copying files from CD-ROM to hard disk, they will be created as read-only files, but some of these files need to be updated. For such files to be used, this read-only property must be cleared.

9.4 Non-Warranty Repair CC provides a repair service for all its products. Repair charges are based upon a fixed fee basis depending upon the complexity of the product. Therefore, Customer Service can provide a quotation on the repair cost at the time a Returned Material Authorization (RMA) is requested. Customers pay the cost of shipping the defective product to CC and will be invoiced for the return shipment to their facility. No repair will be performed without customer approval. If a product is determined to be unrepairable, the customer will be asked if the product can be replaced with a refurbished product (assuming one is available). Under no circumstances will CC replace a defective product without customer approval. Allow ten working days for repairs. 9.5 Returning Products for Repair To schedule service for a product, please call CC Customer Service support directly at +1-630- 963-7070 (U.S.) or +44 (0)24 7641 3786 (U.K.). Have the product model and serial number available, along with a description of the problem. A Customer Service representative will record the appropriate information and issue, via fax, an RMA number—a code number by which we track the product while it is being processed. Once you have received the RMA number, follow the instructions of the Customer Service support representative and return the product to us, freight prepaid, with the RMA number clearly marked on the exterior of the package. If possible, reuse the original shipping containers and packaging. In any event, be sure you follow good ESD-control practices when handling the product, and ensure that antistatic bags and packing materials with adequate padding and shock-absorbing properties are used. CC is not responsible for any damage incurred from improper packaging. Shipments should be insured for your protection. Ship the product, freight prepaid, to the location from which it was purchased:

10 Appendix
10.1 Modbus Message Format The Modbus protocol uses serial transmission. One Modbus transaction consists of a Query message and a Response message. A Modbus-over-ARCNET message consists of: • ARCNET Header • Modbus Message
The ARC-EVS supports the use of two Modbus functions:
• Function Read Holding Registers (3H) — which reads the status of the input LEDs on the AEB
• Function Preset Multiple Registers (10H) — which writes a value to the output LEDs on the AEB The formatting of these two functions is illustrated below:
