AD12-8 Output Connector Pin Assignments

Connections are made to the AD12-8 card via a 37-pin D type connector that extends through the

back of the computer case. The female mating connector can be a Cannon #DC-37S for soldered

connections or insulation displacement flat cable types such as AMP #745242-1 may be used. The

wiring may be directly from the signal sources or may be on ribbon cable from screw terminal

accessories such as The UTB. The pin assignments are as follows:
