The SA/FC bus port on the front of the expansion module is an RJ-12, 6-position modular jack that provides a connection for devices on the SA bus , a Bluetooth® Commissioning Converter, or an FX-ZFR/ZFR Pro Wireless Router (depending on which wireless system the FX-PCX is operating on).
The SA/FC bus port is connected internally to the SA/FC bus terminal block. See Table 1 for more information. The SA/FC bus Port pin assignment is shown in Figure 1.
