BR2 Router – BACnet Network Router
The BR2-A - BACnet router provides routing between BACnet/IP, and BACnet ARCNETnetworks. This allows integrators to mix and match these two BACnet network datalink technologies within a single BACnet Internetwork.
The BR2 Router is enclosed in a metal case that can be mounted standalone or in a 1U rack space. The unit has one ARCNET connector and one Ethernet 10/100 RJ45 connector.
The ARCNET connector is an industry standard BNC connectore for 93 Ohm (RG62) cable. It operates at the standard 2.5 Mbps and by default uses normal timeouts though it can be set for one of the three available ARCNET extended timeouts settings used in long cable run segments. Logically and physically 254 devices can be addressed. The ARCNET is not terminated internally to give the user flexibility in connections and topologies used.
The Ethernet port uses a standard shielded RJ45 connector with integral LEDs. Connection status can quickly be ascertained from the Link and Activity LEDs on each interface.
An embedded web server allows for commissioning and configuration and troubleshooting via a standard web browser. A power LED is present along with the LEDs for interface status on each interface.
