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.
