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 single-mode fiber cable of 9/125µm.
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)
