8-PORT SERIAL HOST ADAPTER PCI
Appendix A: Troubleshooting
A.1 Using the Serial Utility CD-ROM
A serial utility CD-ROM comes with the serial host adapter for use in
troubleshooting. If you still cannot solve a problem after reading this chapter,
call for technical support.
1. Identify all I/O adapters currently installed in your system, including your
on-board serial ports, controller cards, sound cards, etc. Identify the I/O
addresses used by these adapters, as well as the IRQ (if any).
2. Configure your serial host 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 adapter is using a unique IRQ. While this adapter does allow
the sharing of IRQs, many other adapters (such as SCSI adapters and on-
board serial ports) do not. The IRQ is typically selected via an on-board
header block. Refer to Chapter 3 for help in choosing an I/O address
and IRQ.
4. Make sure the adapter is securely installed in a PCI slot.
5. For Windows 95/98/2000/Me/XP and Windows NT, the diagnostic tool
"WinSSD" is installed in the Adapter folder on the Start Menu during the
startup process. First find the ports using the Device Manager, then use
"WinSSD" to verify that the ports are working.
6. When running DOS, Windows 3.x or other operating systems, refer to the
serial utilities CD-ROM and this manual to verify that the adapter is
configured correctly. The supplied software contains a diagnostic program
"SSD" that runs under DOS and will verify if an adapter is configured
properly. This diagnostic program is easy to use. Refer to the README.txt file
on the supplied CD-ROM for detailed instructions on using "SSD."
