BAPI BA-FOX Transceiver RS-485 to Fiber Optic

BAPI recommends fiber optic cable for HVAC communications networks that travel between buildings. The FOX - Fiber Optic Transceiver converts the RS-485 data from the copper network to a fiber optic signal for transmission to other buildings. A FOX in the other building converts the fiber optic signal back into RS-485 for the remote copper network. The FOX module accepts the multi-mode fiber cable on standard ST connectors. The copper RS-485 connection is made on the 8-pole plug along with the power and ground connections. The FOX also plugs into the communications repeater backplane (RBP). Each FOX module consumes one unit load on the RS-485 bus. A green power LED indicates that 12 VDC is present to the module. A red LED at each fiber cable connection fl ashes when data is transmitted or received.
