The ComNet™ FDX4D(M)(S)1 Series data transceiver series provide transmission of four bi-directional data channels over one optical fiber and are ideal for use in unconditioned roadside or out-of-plant installations. The data channels can be set independently for RS232, RS422 and 2 or 4-wire RS485 with tri-state support. Plug-and-play design ensures ease of installation and no electrical or optical adjustments are ever required. Bi-color (Red/Green) LED indicators are provided for rapidly ascertaining equipment operating status. Packaged in the exclusive ComNet ComFit housing, these units may be either wall or rack-mounted, or may be DIN-rail mounted by the addition of ComNet model DINBKT1 adaptor plate.

The ComNet™ FDX55 series consists of fully-digital transceiver units designed for implementing simplex or full-duplex RS232 Drop-and-Repeat poll-and-respond traffic signalization/communications data networks utilizing one or two optical fibers. These environmentally-hardened units are ideal for use in unconditioned out-ofplant or roadside installations and the master-configured transceiver unit may be located anywhere within the network, making this equipment ideal for applications involving on-street master controllers with upstream and downstream communication requirements. These units are compatible with the FDX50, FDX51 and FDX52 Series of optical modems, and ComNet model FDX55BE may be used as a cost-effective solution for use as a line-terminating transceiver. Manually resettable anti-streaming is included for unparalleled network protection. Optional battery backup capability provides the highest level of network reliability in the event of a loss of local prime operating power, and maintains continuous communications channel operation. Plug-and-play design ensures ease of installation and no electrical or optical adjustments are ever required.

The ComNet FDX60(M,S)[-M] data transceivers provide point-to-point transmission of simplex or duplex EIA RS232/RS422/RS485 (2W/4W) data signals over one or two optical fibers. The transceivers are transparent to data encoding allowing for broad-range compatibility. Models within this series are available for use with multimode or single mode optical fiber.
