DESCRIPTION
The A/B Switch allows secure and safe switching between computer or 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 contact closure to
the A/B Switch via the RJ-45 Remote Port. The switching takes place when 4-GND and Pin-6 make or break con-
tact. If power is ever lost to the A/B Switch, the relays with switch to Port-A and continue working without
power.

also present to indicate that the A/B Switch has power applied.

tions and power are protected from surges via internal transorbs.
