Appendix B – Troubleshooting
Following these simple steps can eliminate most common problems.
1. Install software first. After installing the software then proceed to adding the hardware. This
places the required installation files in the correct locations.
2. Read this manual thoroughly before attempting to install the adapter in your system.
3. Use Device Manager under Windows to verify proper installation. Refer to the Verifying Hardware
section of this manual for instructions.
4. Several utilities with source code are included to verify the functionality of the inputs and outputs
and to aid in application development. To test the inputs, you need to supply the turn-on voltage
with a minimum of 3mA (maximum input current is 50mA) to trigger an input. Consult the pin out
diagrams to test at the card edge connector or at the end of the cable.
5. Use the VCTest to verify the basic I/O functionality of your digital I/O board. The source code is
included to simplify application development in the programming language C.
