Functional Description

This section describes the general layout of the PIO-32 Series boards and
provides schematics of the typical input and output circuits.
The PIO-32 Series boards are channel-to-channel isolated and handle
digital voltages in a broader range than standard TTL levels. Optional
accessories for the board include screw terminal panels (STPs) and the
C-3200 cables. The C-3200 cables are 30-inches long; they let you route
the signals from 40-pin headers on the board through a slot in the rear
panel bracket to 37-D male connectors. You connect the 37-D connectors
to the optional STPs.
Figure 2-1 shows the general layout of PIO-32 Series boards. Note the
ribbon headers, labeled J1 and/or J2, on your board; these ribbon headers
provide 16 digital input or output channels each. The orientation of the
headers differs among the boards, as shown in Figure 2-1.
