Key Features and Benefits

• 10/100Base-T Fast Ethernet allows modules to serve as a BACnet router between BACnet/IP system backbone and field devices subnetwork.
• Native BACnet communications to field devices over a high-speed ARCNET 156 kbps or BACnet MS/TP network.
• Can route messages from BACnet/IP to BACnet-over-Ethernet, providing compatibility with older BACnet systems.
• A wide range of open and proprietary protocol translator drivers allow the LGR to also serve as a gateway to other manufacturers equipment.
• Designed with a high-speed true 32-bit microprocessor with cache memory, Fast Ethernet controller, high performance
• 32-bit serial communications co-processor, and ARCNET communications co-processor, LGR routers have the horsepower to serve the most demanding translation and communications functions.
• Can support hundreds of individual control programs written in ALC's legendary Eikon graphic programming language. LGRs can handle the toughest system integration control programs.
• 16 MByte battery-backed SDRAM (32 bit wide), with 12 MBytes available for use, stores application programs, trends and other data when power is lost.
• 8 MByte Flash memory (32 bit wide) for easy field upgrades over the network.
• Battery backed real-time clock provides true standalone capabilities. LGRs recover from power failures providing full continuity of operations, even when communications are disrupted.
• Rnet port supports Automated Logic’s line of RS room sensors and BACview6 local operator interface, and provides local access to the system.
• Enhanced local access is also available on EIA-232 port.
• Tough construction delivers superior performance and reliability. Control modules are constructed with a rugged aluminum cover which provides optimum electrical protection and noise immunity.

The LGR250 is a general purpose control module that you can use for a variety of applications. For example, the LGR250 can act as a controller, a BACnet router, and a protocol translator.

The LGR is an extremely powerful, high-speed device router/gateway that can connect hundreds of control modules to a BACnet/IP backbone. Support for BACnet/IP, BACnet-over-Ethernet, ARCNET 156 kbps, MS/TP, and BACnet PTP communications are standard. A wide range of open and proprietary protocol translator 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.
