The FC bus port on the front of the controller is an RJ-12, 6-position modular jack that provides a connection for the Mobile Access Portal (MAP) Gateway or the ZFR/ZFR Pro Wireless Field Bus Router.
The FC bus port is connected internally to the FC bus terminal block. For more information about the FC Bus port functions, requirements, and ratings, see Communications bus and supply power terminal block. The FC bus port pin assignment is shown in Figure 1.
