An additional setting enables the K-AB card to be used in a multi-circuit gang (simultaneous) switching

arrangement. When used in this manner, one master card controls one or more slave cards. Jumper

Only one card in each card nest can be set as Master.

Connect External Control Source

Standalone models use a nine pin D Subminiature female connector to access the externally supplied

signals. Dataprobe supplies a mating connector kit to assist in fabrication of the proper control cable.

Rack Mounted cards have Control leads terminate on 50 pin Telco connectors on the rear of the

K-AB-R-12 nest. See Appendix A for 9 Pin and Telco Connector Pinouts.

The K-AB is often used in conjunction with other Dataprobe remote switch controlling equipment:
