The Sensor Actuator Bus (SA Bus) port on the VAV Box Balancing Sensor is a 6-pin, RS-485 port designed to connect the VAV Box Balancing Sensor to an accessible SA Bus port on the FX-PC controller directly or through the controller’s connected network sensor, using the cable assembly provided. The SA Bus port is a straight one-to-one connection (not a crossover). The maximum allowable cable length is 100 ft.

Do not plug the SA Port cable into a standard phone jack.
