INSTALLATION AND OPERATION MANUAL

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.

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.

INSTALLATION AND OPERATION MANUAL FDX70E(A,B)(M,S)1 FAULT CONDITIONS A fault condition is when a FDX70E unit system loses power or optical link. The FDX70E 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 FDX70E in the system goes from closed to open. In addition, the STATUS LED on every FDX70E in the system goes from solid green to solid red.
