Troubleshooting

If you are experiencing problems with the RocketPort uPCI Plus 422, review the
troubleshooting procedures for your system before calling Technical Support.

Before Calling Technical Support

Review the following information before calling Technical Support because they
will request that you perform many of the procedures or verifications before they
will be able to help you diagnose a problem.

Verify the cabling using

Note: Most customer problems reported to Comtrol Technical Support are

eventually traced to cabling or network problems.

If you have not done so, run the diagnostics (

Verify that you have installed the latest RocketPort uPCI Plus 422 device
driver, see

on Page 6.

If necessary, remove or update the existing driver using the procedures in the
RocketPort uPCI Plus 422 Device Driver Installation Guide for Windows or
README file packaged with the FreeBSD, Linux, QNX, or SCO OpenServer

RocketPort uPCI Plus 422 Diagnostics

This subsection describes how to create and run the bootable diagnostic to verify
that the RocketPort uPCI Plus 422 hardware is functioning properly. The
RocketPort uPCI Plus 422 is shipped with a bootable diagnostic on the Software
and Documentation
CD that executes hardware diagnostics.

You can use the diagnostic to:

Confirm that the hardware is functioning

Determine resolutions to conflicts during installation

Perform a stress test on all RocketPort uPCI Plus 422 ports in the system

The diagnostic requires a loopback plug to test a port or ports. A single loopback
plug is shipped with the RocketPort uPCI Plus 422. You can build additional
loopback plugs or move the loopback plug to the port you want to test. See

Connecting RS-422 Serial Devices

on Page 9 if you want to build loopback plugs.
