The D9130-R3 from GE Security is a RS232 Data Repeater, SM Laser, 2 Fibers, Db25, Rack Mount. The IFS series D9100 consists of fully-diital transceiver units designed for implementing simplex or full-duplex RS-232 drop-and-repeat poll-and-respond traffic signalization/communications data networks utilizing two optical fibers. These environmentally-hardened units are ideal for use in unconditioned out-of-plant 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 communications requirements. The D9100-series may be used in a conventional single-master/multiple local network architecture, or in a dual-master/bus multiple local configuration for higher levels of communications reliability. Manually resettable anti-streaming is included for unparalleled network protection. Optional battery back-up capability provides the highest level of network reliability in the event of a loss of local 115 VAC prime operating power, and maintains continuos communications channel operation. Plug-and-play design ensures ease of installation and no electrical or optical adjustments are ever required. LED indicators are provided for rapidly ascertaining equipment operating status, and these units are available in either stand-alone or rack-mount configurations.
