The A/B Switch allows secure and safe switching between RS-530 or any ITU V.11 data ports. The unit supports switching 4-wires of user data traffic from the common port to Ports A or Port B. All switching is accomplished with dry contact positive latching relays for years of dependable service. In the event of local power failure, the A/B Switch will default to Port A.

The switching between Port A to Port B are accomplished with a remote device that applies a positive or negative voltage to the A/B Switch via the RS-232 RJ45 port.

The front panel has three status LED’s that present the user with Port A or Port B active status. A power LED is also present to indicate that the A/B Switch has power applied.
