The PCI-DIO96 has four 8255 chips (1,2,3,4). Each chip has three ports (A,B,C). Each port has a maximum of 8 digital I/O lines that can be configured as inputs or outputs.
Use a separate driver block for each port. To configure the port as input, use the digital input driver block.

TTL low = 0.0
Enter numbers between 1 and 8 to select the digital input lines used with this port. This driver allows the selection of individual digital input lines in arbitrary order. The number of elements defines the number of digital lines used.
For example, to use all of the digital inputs for one port, enter
Number the lines beginning with 1 even if this board manufacturer numbers the lines beginning with 0.
From the list choose either
Port parameter defines which port of the
current 8255 chip is used for this driver block.
From the list choose
Chip parameter defines which of the four 8255
chips is used.
Enter the base sample time or a multiple of the base sample
-1 means sample time is inherited).
