Two toggle switches control the two DB9 interface A/B switch channels of the Model 7211.
LED indicators display the current position of each network switch channel.
A transition from contact CLOSE (down) to OPEN (up) of the toggle switch will cause the channel to switch to A. A transition from contact OPEN (up) to CLOSE (down) of the toggle switch will cause the channel to switch to B.
Upon power up, the Model 7211 reads the static contact state. If OPEN, switch to position A; if CLOSED, switch to position B. After power up, the unit looks for transitions.
A single DB9 female Remote port accepts a straight through DB9 cable.
