The LR-01 offers an easy way to extend the distance between 78 kbit/s LonWorks TP/FT-networks using a fiber optic link. The LR-01 is completely transparent to the protocol therefore installation is simple as no new network addresses are needed. The LR-01 is equipped with either one (LR-01PP) or two pairs of fiber optic receivers and transmitters. This allows the user to build either point to point-, bus- or redundant ring topology fiber links. In a fiber ring, one of the LR-01 units will be ringmaster and will have the responsibility to stop messages from looping around the ring. The LR-01 has a built-in redundancy system that provides for fault tolerance in the fiber rings.
