FOX - RS-485 Fiber Optic Transceiver
Electronic Technician Assistant (ETA)

  BAPI recommends fiber optic cable for HVAC communications networks that travel between buildings. Fiber optic cable is not electrically conductive therefore it is not affected by electrical disturbances such as lightning strikes, radio transmitters or system ground variations.
   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 flashes when data is transmitted or received.
