FDX70E(A,B)(M,S)1
MULTI-PROTOCOL RS232/422/485
POINT-TO-POINT DATA TRANSCEIVER
The ComNet™ FDX70E(A,B)(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 pair of FDX70E units (as FDX70EA and FDX70EB) can support
one full-duplex or half-duplex data channel. These transceivers also feature
data translation to convert between data protocols. 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. Linear and point-to-point topologies are also possible
using ComNet FDX72(M,S)1 models.
Bi-color (Red/Green) LED indicators are provided for rapidly ascertaining equipment
operating status. See Figure 7 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 – 8 for complete installation details.

Optical Port A in FDX70EA connects to
Optical Port B on the FDX70EB unit.
Similarly, when used as part of a dropinsert-repeat topology with the ComNet
FDX72 series, Optical Port A must be
connected to Optical Port B of the next
unit. Refer to Figure 9 on Page 6.
