High-Speed BACnet Routing & Integration

The Automated Logic® LGR router is an integral component of the WebCTRL® building automation system. The LGR router is an extremely powerful, high-speed router/gateway that can connect hundreds of control modules to a BACnet/IP backbone. Support for BACnet/ IP, BACnet over Ethernet, BACnet over ARC156, and BACnet over MS/TP communications are standard. A wide range of open and proprietary protocol drivers allow the LGR to also serve as a gateway to other manufacturers’ equipment. Fully programmable, the LGR can also execute complex control strategies for high-level system integration.
