Interlogix D19130SHR RS232/422/485 Digital Self Healing Ring, SM, 2 Fibers

The IFS D19100SHR series Self-Healing Ring Transceiver unit is a fully-digital transceiver designed for implementing traffic signalization/communications data networks of the highest possible reliability. Unlike competing products, the multiple-master capability of this series provides full protection against the possibility of a single point of failure, significantly enhancing the reliability and availability of the network. Primary and alternate-master transceiver units may be either co-located or diversity located, and the data input/output interconnection to the primary and alternatemaster units is achieved by the use of a simple “Y” electrical cable. Full 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. 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.
