The PCI-6503 has one 8255 chip with 3 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. By selecting the digital input driver block, the port is configured as input.
I/O Module Input

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 starts numbering the lines with 0.
From the list, choose either
C. The I/O board has an
8255 chip with 3 ports. The Port parameter defines
which port of the 8255 chip is used for this driver block. Each port has
a maximum or 8 digital lines that can be configured as inputs or outputs
depending on which driver block is chosen. In each case, one block is
required for each port.
Enter the base sample time or a multiple of the base sample

If two or more boards of this type are in the target computer, enter the bus number and the
PCI slot number of the board associated with this driver block. Use the format
To determine the bus number and the PCI slot number, type:
