Appendix A - Troubleshooting 
Sealevel Software is supplied with the Sealevel Systems adapter and may be used in the troubleshooting procedures. 
Using this software and following these simple steps can eliminate most common problems 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
. 
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 supplied Sealevel Software and this User Manual to verify that 
the Sealevel Systems adapter is configured correctly. This software contains a diagnostic program ‘SSD’ 
(D:\software\seacom\Other\DOS\DIAG, where D: = the driver letter of your CDROM drive) will verify if an 
adapter is configured properly. This diagnostic program is written with the user in mind and is easy to use 
6.  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. 
7.  Always use the Sealevel Systems diagnostic software when troubleshooting a problem. This will eliminate any 
software issues from the equation.
