COMNET FDX72M1SHR overview

  • 1Description

The Multi-Protocol RS232/422/485 Self-Healing Ring Universal Data Transceiver from ComNet 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 these transceiver units can support one full-duplex or two half-duplex data channels. This transceiver also features data translation to convert between data protocols. It features a multimode fiber cable of 62.5/125µm.

Data re-clocking and regeneration functions permit a high number of transceiver/controller units to be used within the network. This environmentally-hardened transceiver is ideal for use in unconditioned out-of-plant or roadside installations and requires only one optical fiber between units to implement a fully self-healing 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 without requiring electrical or optical adjustments.

  • Meets EIA RS232 and RS422/RS485 (2 or 4-wire) specifications (simplex or duplex operation)
  • Two data channel capability with 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 allows high number of transceiver units to be used within a network
  • Supports 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
  • Provide serial data protocol conversion between nodes (consult factory)
  • Designed to meet full compliance with the environmental requirements including ambient operating temperature, mechanical shock, vibration, humidity with condensation, high-line/low-line voltage conditions and transient voltage protection) of NEMA TS-1/TS-2 and the Caltrans Specification for Traffic Signal Control Equipment
  • Designed to ensures 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 not required
  • Hot-swappable rack modules
  • Interchangeable setup between standalone and rack mount
  • DIN-rail mountable (requires the DINBKT1 or DINBKT4 adapter plate)
