2-PORT RS-232/422/485 PCI HOST ADAPTER

5.Troubleshooting

5.1The Serial Utility Diskette

The Adapter comes with a Serial Utility Diskette that has diagnostic software on it. We recommend that you always use this software first when you troubleshoot problems, because it can help resolve most common problems related to software and operating-system incompatibilities without requiring you to call Technical Support.

1.Make sure the Adapter is securely installed in a motherboard slot.

2.Use the supplied diskette and User Manual to verify that the Adapter is configured correctly. The supplied diskette contains the diagnostic programs “FindPCI,” “SSD” (for DOS), and “WINSSD” (for Windows NT, 3.1, or 95), which will verify if an adapter is configured properly. First, run the “FindPCI” utility and record the base I/O addresses and the IRQ assignments, these will be needed for SSD. Next, run the “SSD” diagnostic program (for DOS) or the “WINSSD” program (for Windows). Refer to the \dos\diag\diag.txt file on the supplied diskette for detailed instructions on using “SSD.”

The Serial Utility Diskette might also contain README-style text files. You can consult these for information about issues that might have arisen since this manual was written, and for application-specific information.
