The BASRT-B BACnet multi-network router provides stand-alone routing between BACnet networks such as BACnet/IP, BACnet Ethernet, and BACnet MSTP. This allows the system integrator to mix BACnet network technologies within a single BACnet internetwork. There are two physical communication ports on the BAS Router. One is a 10/100 Mbps Ethernet port and the other an isolated MS/TP port. Configuration is accomplished via a web page. The BACnet router is housed in a plastic case that is powered from a USB port on a laptop computer. There is one MS/TP port and one 10/100 Mbps Ethernet port.
