### Using Digi's Diagnostic Program for PCI Adapters

To help you verify the operation of your Digi adapter, use the diagnostics tool provided by Digi. The diagnostic runs a series of tests on the adapter.

#### Accessing the Program

The diagnostic program is located in the Diags\pci directory on the Digi CD. The program is called UD-PCI.EXE.

If you can't see the CD driver from DOS, you can create a diagnostic diskette to use. For information about creating a diskette, see:

Creating Installation and Diagnostic Diskettes

#### Running the Program

1. After starting MS-DOS, insert the diskette containing the diagnostic software in the diskette drive (or the CD into the CD drive).
   Access the program in the following directory (located under Diags on the CD):
   \PCI\UD-PCI

2. Select an adapter family from the list.

3. The program will display the adapter base address that was assigned by the host. The other parameters will be filled in with default values similar to the following:

   Port: | 1
   EIA-232/422: | 232
   Loopback: | No
   Continuous Test: | Yes
   Stop on first: | Yes

4. Now press <R> to start the tests. The tests will be run consecutively, and pass/fail status will be indicated on the right hand side of your screen.

5. If all the tests pass, the adapter is functioning correctly and you are ready to install the device driver software.
