This section describes the setup procedure to be performed before you can start developing application
programs for the board using the bundled CD-ROM “API Function Library Package API-PAC(W32)”.
Taking the following steps sets up the software and hardware. You can use the diagnosis program later
to check whether the software and hardware function normally.
Step 1 Installing the Software
Step 2 Setting the Hardware
Step 3 Installing the Hardware
Step 4 Initializing the Software
Step 5 Checking Operations with the Diagnosis Program
If Setup fails to be performed normally, see the “Setup Troubleshooting”section at the end of this

If you install two or more boards on one personal computer, assign a different ID value to each of the
boards to distinguish them.
The board IDs can be set from 0 to Fhto identify up to sixteen boards.
If only one board is used, the original factory setting (Board ID = 0) should be used.
Setting Procedure
To set the board ID, use the rotary switch on the board. Turn the SW1 knob to set the board ID as shown
