IntroductionExtend the distance of LonWork networks by Fibre Optics
FeaturesThe Westermo LR-11 router offers an easy way to extend the distance between LONWORKS 78 kbit/s TP/FT network segments using a high-speed 1.25 Mbit/s backbone fibre optic network link. LR-11 is based on Echelons RTR-10 standard router core module, this allowing standard configuration and installation with tools as LonBuilder and LonMaker. The LR-11 is equipped with either one (PP-version) or two pairs of fibre optic receivers and transmitters. This allows the user to build either point to point-, bus- or ring topology fibre links. In a fibre ring, one of the LR-11 units will be assigned as a ring master and then having the responsibility to stop messages from looping around the ring. The LR-11 has a built-in redundancy scheme that provides for fault tolerances in the fibre ring
