Multi-Protocol RS232/422/485 Data Transceiver
Featuring Self-Healing Ring Operation
FDX72(M,S)1SHR
The ComNet™ FDX72SHR series Self-Healing Ring Transceiver unit is a fully-digital
modem designed for implementing RS232, RS422 or RS485 2 or 4-wire data
communications networks of the highest possible reliability. A network of FDX72SHR
units can support one full-duplex or two half-duplex data channels. These transceivers
also feature data translation to convert between data protocols. 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 and, unlike many competing
designs, only one optical fiber is required between units to implement a fully selfhealing ring. Bi-color indicating LEDs are provided for rapidly ascertaining equipment
operating status, including the location of fiber breaks. Plug-and-play design ensures
ease of installation, and no electrical or optical adjustments are ever required.
FEATURES
› Meets EIA RS232 and RS422/RS485 (2 or 4-wire)
specifications (Simplex or Duplex Operation)
› Two Data Channel Capability: One full duplex or two half-
duplex channels
› Only one optical fiber required between units for Fault
Tolerant/Self-Healing Ring Operation
› Full data re-clocking and regeneration: no limit to the number
of transceiver units used within the network
› Supports supervised multiple master architecture for
unparalleled network reliability
› Remote Fault Indication allows the user to determine when a
fiber break or loss of prime operating power has occurred, or
a transceiver in the field has failed
› LED status indicators provide rapid indication of all critical
operating parameters, including the location of fiber breaks
or failed transceivers
› May be used to provide serial data protocol conversion
between nodes (consult factory)
› Designed to meet full compliance with the environmental
requirements (ambient operating temperature, mechanical
shock, vibration, humidity with condensation, high-line/lowline voltage conditions and transient voltage protection) of
NEMA TS-1/TS-2 and the Caltrans Specification for Traffic
Signal Control Equipment.
HARDENEDINCLUDED
› Robust design assures extremely high reliability in
unconditioned out-of-plant/roadside environments
› NTCIP compatible
› Voltage transient protection on all power and signal input/
output lines provides protection from power surges and other
voltage transient events.
› Wide optical dynamic range: optical attenuators are never
required
› Hot-swappable rack modules
› Interchangeable between stand-alone or rack mount –
ComFit package
› Units may be DIN-Rail mounted by the addition of ComNet
model DINBKT1 or DINBKT4 adaptor plate
› Lifetime Warranty
1 OR 2*
