succeeded in getting to the last step, you’re ready to connect the hardware and attempt to
communicate with it.
2. After you have verified that you are able to communicate through your COM port, set up your COM
card for half-duplex, RS-485, and wire it up using two wires to the Pod. (You may need to move
some jumpers on the COM board to accomplish this. Or if you’re using our RS-232/485 Converter,
please connect it at this time. Communication with the Pod should be two-wire RS-485, Half-
Duplex with Termination and Bias applied. Also select No Echo (where Echo exists) on the COM
card. See your manual for the COM card for further details.) You also have to wire appropriate
power to the Pod terminals. See the Screw Terminal Pin assignments for help with this. For best
results, you’ll need +12V and a return to power the pod in the non-isolated mode. For bench testing
and setup with one power supply, you’ll need to install wire jumpers between the following
terminals on the terminal block: ISOV+ to PWR+, and ISOGND to GND. This defeats the optical
isolation feature of the Pod, but eases the development setup and only requires one power supply.
You should also check the processor board as described in Option Selection to ensure the jumpers
JP2, JP3 and JP4 are in the /ISO position.
3. Verify your wiring, then turn on power to the Pod. If you’re checking, the current draw should be
approximately 250mA.
4. Now you can again run the setup and calibration program(DOS, Win3.x/9x). This time the setup
program should auto-detect the Pod from the auto-detect menu item, and allow you to run the
calibration routine. If you’re using Windows NT, you can run the setup program to set the jumpers
regarding isolated or non-isolated communication. To run the calibration routine, just use a DOS
boot disk, then run the program. We can provide this if necessary.
Running WinRISC
1. For Windows 9x/NT 4/NT 2000, start the WinRISC program, which should be accessible from the
start menu (Start | Programs | RDAG12-8 | WinRISC). If you can’t find it, go to Start | Find | Files
or Folders and search for WinRISC. You can also explore the CD and look for
disks\tools.win\Win32\WinRISC.exe.
2. Once you’re in WinRISC, select a baud rate of 9600 (factory default for the Pod). Select Local Echo
and the following other settings: Parity-Even, Data Bits-7, Stop Bits-1. Leave other settings at the
default. Select the verified COM port (top left) and click on “Connect”.
3. Click into the main box. You should see a blinking cursor.
4. Type a few characters. You should see them print to the screen.
5. Proceed to the section “ TALKING TO THE POD ”.
