Troubleshooting Tips

Use these troubleshooting tips if you should have problems with your installation:

• An error report is logged if a problem is encountered while initializing the device. These errors can be viewed using the Event Viewer, EVENTVWR.EXE.
• Use the program WINMSD.EXE to determine the hardware resources allocated to each device. If a ClassicBoard device fails to initialize, no resources are allocated for that device.
• Use the Digi Port Authority (DPA) for Windows application to test and monitor all serial ports configured in your system. DPA displays specific information for supported Digi adapters. You can download DPA from the Digi Support Web site (http://supportold.digi.com). Use it to verify that the ports can transmit and receive, either on a single port with a loopback adapter, or between two ports with a null modem cable.
• Use the Digi Neo and ClassicBoard PCI Diagnostics program to test adapter hardware functions if you suspect a hardware problem. You can download the diagnostics program from the Digi Support Web site (http://supportold.digi.com). See the release notes for information about using the program.
• When performing baud mapping, your application will not be aware that the serial ports are operating at a different baud rate than the selected rate. Large differences between the To and the From values may cause problems in your applications. If you are experiencing problems with baud mapping, try to choose To and From values that are as close as possible. For example, mapping from 115.2k to 460.8k will likely cause fewer problems than mapping from 14.4k to 460.8k.
