Driver Block Parameters
Channel Vector - 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 any 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
[1,2,3,4,5,6,7,8]
Number the lines beginning with 1 even if the board manufacture starts
numbering the lines with 0.
Port - From the list choose either A, B, or C. The I/O board has a 8255 chip
with 3 ports. The port name defines which port of the 8255 chip is used for this
