FDX72(M,S)1

MULTI-PROTOCOL RS232/422/485 DATA TRANSCEIVER
FEATURING LINEAR DROP-INSERT-REPEAT

The ComNet™ FDX72(M,S)1 series Transceiver unit is a fully-digital 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 FDX72 units, used with the ComNet FDX70E(A,B)(M,S)1 series
products as end points, can support one full-duplex data channel or two half­duplex 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

Bi-color (Red/Green) LED indicators are provided for rapidly ascertaining equipment
operating status. See Figure 8 on Page 5 for an explanation of LED indications.

These units are interchangeable between stand-alone or card-cage mount
configurations. See Figure A on Page 7 for mounting instructions.

See Figures 1 – 9 for complete installation details.
