Resources Properties
The majority of the time, we recommend that you use the automatic settings. The
operating system assigns an interrupt and memory location for you. An interrupt
must be assigned to the 1784-PCMK card. Verify that there is an interrupt assigned
and no resource conflicts display in the Conflicting Device list.
In the unlikely event that you have a resource conflict, you may need to assign a
specific interrupt or memory range to free the resource for another device.
To manually assign an interrupt:
1. Deselect the Use automatic settings box.
2. Click Interrupt Request .
3. Click Change Setting... and select a new interrupt location number
(address).
Most systems have 15 interrupt locations available for you to assign. If you have
more than 15 devices that need an interrupt location, you may need to disable
another device, such as an unused serial or parallel port to make an interrupt
available for the PCMK card.
