4 INTERFACING

The PCM-D24/CTR3 has 24 digital input/output and 3 counters. Because of con-

straints imposed by the number of pins on a 33 pin connector, the access to the count-

ers is limited. A digital ground is provided on pin 33 and in the cable shield clips to

either side of the 33 pins of the connector.

Shown here is a PCM-D24/CTR3 case looking into the connector. The KEY helps to

insure that the cable is inserted in the correct orientation.
