Appendix A - Troubleshooting
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. Try the Sealevel Systems adapter with 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.
4. Make sure the Sealevel Systems adapter is securely installed.
5. For Windows95/98/ME/NT/2000, the diagnostic tool ‘WinSSD’ is installed in the SeaCOM 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. Remember if a “No Echo” mode is selected, a data loopback cannot be accomplished.
7. Always use the Sealevel Systems diagnostic software when troubleshooting a problem. This will eliminate any
software issues from the equation.
