### Troubleshooting Tips

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

- To access Windows troubleshooting assistance:
  1. From the Control Panel, choose System > Hardware > Device Manager > Multi-port serial adapters.
  2. Right-click on the adapter you wish to troubleshoot.
  3. Choose Properties. The adapter Properties page appears.
  4. Choose General to view the Device Status window. If this indicates that the device is not operating properly, choose Troubleshooting and follow the instructions to resolve any basic installation or configuration problems.
- Windows logs an error report if it encounters a problem while initializing the device. You can view these errors using the Event Viewer, EVENTVWR.EXE, supplied with Windows.
- Use the program WINMSD.EXE, supplied with Windows, to determine the hardware resources allocated to each device. If a 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://support.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://support.digi.com). See the release notes for information about using the program.
