DESCRIPTIONThe Extron CTR 8 adds contact closure control to most RS-232 controllable Extron single-output simple or scaling switchers, or to an Extron IP Link control processor. It accepts up to eight contact closure inputs and converts them to SIS™ serial commands that select the corresponding input on an Extron switcher. The contact inputs and tally outputs can be monitored and controlled by an Extron IPLink control processor so it can issue commands to other devices based on the input the CTR 8 receives. Video can be muted and un-muted by pressing a single switch in sequence.

FEATURES
