RS 485 to Fiber Optic Repeater, 1 Output

Product Code: ATK07-00
Model #: FR485/S
$230.00
The FR485 is a RS-485 to fiber optic convertor module available as a single fiber pair output repeater or dual fiber pair output repeater. The FR485 uses OPTEK’sb 850nm, transmitter and receiver with the “ST” connector receptacles for 62.5-125mm (50/125mm) fiber optic cables. The FR485 is biased to transmit distances up to 2.5 km at 78K bps rate.
Description
The FR485 is powered by a 24VAC supply. Network RS- 485 communication is received at the input terminal, filtered, fed into a half duplex RS-485 transceiver, where it is converted into a TTL signal for fiber optic transmission. Separate multi mode fibers are used for transmit and receive. When the FR485 receives a signal via fiber, the TTL signal is converted back to the RS-485 format and sent out on the RS-485 communication trunk. The FR485 operates as a transparent repeater only, which does not perform any additional routing functions and requires no additional software configuration. Led indication is provided on all transmit and receive fiber channels. The FR485 is available as a single or dual channel repeater. The single channel FR485 is used for simple point to point repeating functions. The dual channel FR485 transmits an incoming packet from a single twisted pair, porting to both fiber channels simultaneously, as well as echoing any incoming fiber signal on the other fiber channel. This allows the dual channel FR485 to support Ring, Bus, and point to point topologies
