May 29, 2013 - Cimetrics iupdated its BR2 router, which provides routing between BACnet networks such as BACnet/IP, BACnet ARCNET, BACnet Ethernet, and virtual or tunneled BACnet networks. This allows integrators to mix and match BACnet network datalink technologies within a single BACnet Internetwork. The BR2 router has two communications ports in all cases. One is always a 10/100 Ethernet port and the other is a RG62 Coaxial cable or RS485 twisted pair.
- Connects BACnet systems from different suppliers like Trane BCUs
- Enables campus-wide control systems
- Uses industry's leading BACnet OEM protocol stack (Cimetrics BACstac)
- High bandwidth design
- Easy browser-based configuration
To commission BACnet ARCNET devices one has generally been forced to use a special PC hardware ARCNET interface to communicate with the ARCNET RS485 or Coaxial LAN. The secret is that most BACnet ARCNET software can be run against BACnet/IP and communicate via BACnet Routing to BACnet ARCNET to achieve this configuration/setup connectivity. The Cimetrics BR2-A can accomplish this connectivity. The BACnet/IP port on the BR2-A connects to the PC's Ethernet/TCPIP port using a standard CAT5 cable. The ARCNET port connects to the target BACnet ARCNET LAN (93 Ohm RG62 Coaxial cable or RS485 twisted pair plus ground cable in general). The BR-A can be powered from any 120VAC source. The BR2-A is setup using its embedded webpages. The baud rate of the BACnet ARCNET port is setup to match the baud rate and network number of the existing ARCNET LAN. BACnet details:
- BACnet 135.1-2003 ASHRAE & ISO standard
- BBMD and FD (Foreign Device) support
- BACnet/ARCNET = Co-ax or RS485 twisted pair
- BACnet/IP or BACnet/HTTP with optional encryption
