Description

The ComNet(TM) 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 environmentallyhardened 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 antistreaming 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. 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 rackmounted, or may be DIN-rail mounted by the addition of ComNet model DINBKT1 adaptor plate.
