The SA/FC bus port on the front of the controller is an RJ-12, 6-position modular jack that provides a connection for devices on the SA bus, a Wireless Commissioning Converter, ZigBee® wireless dongle, or a ZFR1811 Wireless Router, depending on which bus the IOM is operating on.
The SA/FC bus port connects internally to the SA/FC bus terminal block. See Table 1 for more information. The SA/FC bus port pin assignment is also shown in Figure 1.
