Appendix A – Troubleshooting
A Serial Utility Diskette is supplied with the Sealevel Systems adapter and will be used in the
troubleshooting procedures. By using this diskette 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. While the Sealevel Systems
adapter does allow the sharing of IRQs, many other adapters (i.e. SCSI adapters & on-board serial
ports) do not. 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 or Windows 3.x refer to the Serial Utilities disk 1 and the User Manual to verify
that the Sealevel Systems adapter is configured correctly. The supplied diskette contains a
diagnostic program 'SSD' that 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 'README' file on the
supplied diskette for detailed instructions on using 'SSD'.
6. For Windows 95 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
eliminate any software issues from the equation.
