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 securely installed in a motherboard slot.
4. 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'.
5. 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.
6. Always use the Sealevel Systems diagnostic software when troubleshooting a problem. This will
help eliminate any software issues and identify any hardware conflicts.
