COMNET FDX57S1 overview

  • 1Description
Provided by third party:

The ComNet FDX57 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 FDX57 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. Plug-and-Play design ensures ease of installation, and no electrical or optical adjustments are ever required.

Key Features
  • Meets EIA RS232 and RS422/RS485 (2 or 4-wire) specifications
  • Two Data Channel Capability: One full duplex or two halfduplex 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
  • May be used to provide serial data protocol conversion between nodes (consult factory)
  • 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
  • Indicating LEDs display equipment operating status, including the location of fiber breaks or failed transceivers
  • Hot-swappable rack modules
  • Interchangeable between stand-alone or rack mount use - ComFit
