Cabling and Wiring
In the digital output example shown in Figure 4-5, the PIO-32OUT board
is used to control the on and off state of a device. The polarity does not
matter in this example.

Connector Pin Assignments
If you are using the C-3200/C-32NN cables, note that the pin assignments
for the 37-D connector and the 40-pin ribbon header are numbered
differently. Figure 4-6 on page 4-7 shows the 37-D cable connector and its
pin assignments for the J1 signals; Figure 4-7 on page 4-8 shows this
connector and its pin assignments for the J2 signals. Figure 4-8 on page
4-9 shows the 40-pin ribbon header and its pin assignments for the J1
signals; Figure 4-9 on page 4-10 shows the ribbon header and its pin
assignments for the J2 signals. Refer to Appendix B for more information
on these pin assignments.
Note:
The positive input signals are labeled P
n
P (where
n
is the bit
number, 0 to 31); the negative input signals are labeled P
n
N (where
n
is
the bit number, 0 to 31).
