Appendix A – Troubleshooting
The adapter should provide years of trouble-free service. However, in the event that device appears to not
be functioning incorrectly, the following tips can eliminate most common problems without the need to call
Technical Support.
1.
Install software first. After installing the software then proceed to Physical Installation section of
the manual.
2.
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.
3.
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.
4.
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.
5.
Make sure the Sealevel Systems adapter is securely installed.
6.
For Windows operating systems, 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, the 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.
