The Sensor (SA Bus) port on the bottom of the controller is an RJ-12, 6-position modular jack that provides a connection for MAP Gateway, the Bluetooth® Commissioning Converter (BTCVT), the VAV Balancing Tool, specified network sensors, or other SA Bus devices with RJ-12 plugs. When the FX-PCA is configured for N2 network communication, you must download and commission the controller using the SA Bus port.
A DIS1710 Local Controller Display also can be connected to the SA Bus port.
The Sensor port is connected internally to the SA bus terminal block. For more information about the Sensor port functions, requirements and ratings, see Table 1. The Sensor Port pin assignment is shown in Figure 1.
