描述
The FT Router 5000 device is used to build high-performance LON routers, enabling multi-channel Free Topology (FT) networks with thousands of nodes in a single installation. The FT Router 5000 combines a Router 5000 core with an FT Smart Transceiver and can be used to build an FT-10 channel half-router with LON communication channel to route LON messages. The FT Router 5000 device includes embedded firmware that implements a half-router and is capable of supporting thousands of nodes using use one of four routing algorithms: configured router, learning router, bridge or repeater. The ability to choose these options allows trading off system performance for ease of installation. The compact form factor of the FT Router 5000 minimizes the space required to develop a half-router. A half-router design that uses FT Router 5000 can be used with another half-router to function as a repeater or interface with other twisted pair physical media such as RS-485, TP-78, TP-1250 or LPT-11.
