Integrate BACnet MS/TP Segments to JACE

While the JACE can receive or route MS/TP traffic over one of its serial ports, there is a limitation of 31 full-load MS/TP devices and a maximum distance of 4000 ft for a MS/TP segment. The network architecture and wiring considerations may also dictate installing MS/TP devices across different locations that make it hard to interconnect them over one MS/TP bus.

Limiting MS/TP segment size speeds up the communication by allowing the device to receive the token quicker compared to a larger segment. Multiple MS/TP segments also help in isolating signal quality issues. The use of BASrouter or BASrouterLX routers allows you to segment your BACnet network by using a router on each MS/TP segment and routing the traffic to IP. Use an Ethernet switch to interconnect the BACnet routers. The JACE then receives all traffic from all MS/TP segments through its Ethernet port.

The BASrouters provide the solution. The BASrouter and BASrouterLX offer stand-alone routing between BACnet/IP, BACnet Ethernet, and BACnet MS/TP networks — allowing the system integrator to mix BACnet network technologies within a single BACnet inter-network.
