FDX57(M,S)

MULTI-PROTOCOL RS232/422/485 DATA TRANSCEIVER
FEATURING SELF-HEALING RING OPERATION

The ComNet™ FDX57(M)(S) series Self-Healing Ring Transceiver unit is a fully­digital transceiver designed for implementing full RS232, RS422 or RS485 2 or
4-wire traffic signalization/communications data networks of the highest possible
reliability. A network of FDX57 units can support one full-duplex data channel or
two half-duplex data channels. These transceivers also feature data translation
to convert between data protocols. Full data re-clocking and regeneration permit
an almost unlimited number of transceiver/controller units to be used within
the network. These environmentally hardened transceivers are ideal for use in
unconditioned out-of-plant or roadside installations.

Utilizing wave division multiplexing technology (WDM), only one optical fiber is
required between units to implement a fully self-healing ring.

Bi-color (Red/Green) LED indicators are provided for rapidly ascertaining
equipment operating status including the location of fiber breaks. See Figure 8
on Page 4 for an explanation of LED indications.

These units are interchangeable between stand-alone or card-cage mount
configurations. See Figure A on Page 6 for mounting instructions.

See Figures 1 – 9 for complete installation details.
