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.
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 by the BIOS or
operating system. Some BIOS setup software will allow changing the IRQ, but others
do not. Another method of changing assigned resources is to try changing PCIe
slots. This will typically cause the BIOS or OS to reassign the resources.
4.
Make sure the Sealevel Systems adapter is securely installed in a motherboard slot.
5.
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.
Always use the Sealevel Systems diagnostic software when troubleshooting a
problem. This will eliminate any software issues from the equation.
