The sensor bus port on the middle left side of the controller, see ‘9’ on Figure 1, is an RJ12, 6-position modular jack that provides a connection for the Smart Building Hub (SBH), the VAV Balancing Tool, specified network sensors, or other sensor bus devices with RJ12 plugs.
The sensor bus port is connected internally to the sensor bus terminal block. See Table 1 for more information on functions, ratings, requirements and cables. The sensor bus port pin assignment is shown in Figure 1.
