INSTALLATION AND OPERATION MANUAL

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 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

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.

INSTALLATION AND OPERATION MANUAL FDX72(M,S)1 FAULT CONDITIONS A fault condition is when a FDX72 unit system loses power or optical link. The FDX72 provides three LED indicators to help identify when and where fault conditions occur in a system: 1. ALARM relay output 2. STATUS LED 3. LINK A and LINK B LEDs When a fault occurs, the ALARM relay on every FDX72 in the system goes from closed to open. In addition, the STATUS LED on every FDX72 in the system goes from solid green to solid red.
