Appendix A - Troubleshooting
Serial Utility test software is supplied with the Sealevel Systems adapter and will
be used in the troubleshooting procedures. By using this software and following
these simple steps, most common problems can be eliminated without the need
to call Technical Support.
1. Identify all I/O adapters currently installed in your system. This includes
your on-board serial ports, controller cards, sound cards etc. The I/O
addresses used by these adapters, as well as the IRQ (if any) should be
identified.
2. Configure your Sealevel Systems adapter so that there is no conflict with
currently installed adapters. No two adapters can occupy the same I/O
address.
3. Make sure the Sealevel Systems adapter is using a unique IRQ. The IRQ is
typically selected via an on-board header block. Refer to the section on Card
Setup for help in choosing an I/O address and IRQ.
4. Make sure the Sealevel Systems adapter is securely installed in a
motherboard slot.
5. When running DOS, Windows 3.x or other operating systems refer to the
Serial Utilities software for that operating system and the User Manual to
verify that the Sealevel Systems adapter is configured correctly. The
supplied software contains a diagnostic program 'SSD' that runs under DOS
and will verify if an adapter is configured properly. This diagnostic program
is written with the user in mind and is easy to use. Refer to the DIAG.txt file
in the dos\diag directory for detailed instructions on using 'SSD'.
6. For Windows 95/98 and Windows NT, the diagnostic tool 'WinSSD' is
installed in the Sealevel folder on the Start Menu during the setup process.
First find the ports using the Device Manager, then use 'WinSSD' to verify
that the ports are functional.
7. Always use the Sealevel Systems diagnostic software when troubleshooting
a problem. This will help eliminate any software issues and identify any
hardware conflicts.
