15. Run the 1784-PCC test utility as described in Chapter 6 to verify the
installation.
If installation fails, refer to Troubleshoot the Card Installation on page 4-11.
Troubleshoot the Card Installation
Use the following sections to determine why the test utility failed.
Check for Resource Conflicts
When you run the PCC setup utility in Windows NT, the utility tries to assign free
resources to the PCC card. If your card used to work, and has now stopped
working, it is probably because the resources originally assigned to the card are
now being used by another device you recently added, such as an Ethernet card.
Try re-running the card's setup utility. Refer to Locate the 1784-PCC Driver for
Windows NT on page 4-5. The utility may be able to automatically find other
resources to assign to the card.
If you do this, and the test utility still fails, you will need to check for resource
conflicts. Possible conflicts include IRQ, memory, or I/O conflicts. To view and
change your resource locations, you will need to view all of your resource
allocations to determine which resouces are free.
To access and change resouce locations:
1. Do one of the following:
• access Windows NT diagnostics (Start ⇒Programs ⇒Administrative
Tools ⇒Windows NT Diagnostics), or
• Select Start ⇒Run and type WINMSD in the Run dialog box. Press
Enter or click Ok.
2. To determine if you have an IRQ conflict, click on the Resources tab.
