Router makes BACnet/IP to BACnet MS/TP connection.

Press Release Summary:

Housed in 35 mm DIN-rail-mounted metal case and powered from 24 Vac/Vdc source, BASRT-B allows BACnet/IP devices to communicate with MS/TP devices. MS/TP port offers optically isolated communication and enables up to 127 devices to be addressed. All MS/TP baud rates are supported from 9.6-76.8 kbps. Through auto-negotiation and Auto-MDIX, 10/100 Ethernet port automatically matches duplex setting, flow control, data rate, and signal polarity to what is needed by attached equipment.

Original Press Release:

Ethernet Infrastructure + BAS Router = Your Ideal Solution

Use Contemporary Controls' BAS Router to Make the BACnet/IP to BACnet MS/TP Connection

Downers Grove, IL (April 1, 2008) "Contemporary Controls' BAS Router is
designed specially for the next generation of building automation networks," says Sales Manager Joe Stasiek. "Built with excellent hardware, the BASRT-B can help you increase operational efficiency and service flexibility."

If you have BACnet MS/TP devices to install, but no MS/TP home run is available, use the BAS Router to make the BACnet/IP to BACnet MS/TP connection. With the BAS Router you can use the Ethernet infrastructure and locate the MS/TP devices where you need them. You can take advantage of the many MS/TP devices in the marketplace and connect them to any BACnet/IP enabled controller. And of course, if you're trying to maintain a standard selection of spare MS/TP parts, you can employ the same MS/TP devices connected to MS/TP controllers as those connected to the BACnet/IP controller.

This device routes between BACnet/IP and BACnet MS/TP networks as per the ANSI/ASHRAE 135-2004 standard. It allows BACnet/IP devices to communicate with MS/TP devices. The router is configurable via its webpage.

The BASRT-B is housed in a metal case that mounts on 35-mm DIN-rail and is powered from a 24 VAC/VDC source. The unit contains one MS/TP port and one 10/100
Mbps Ethernet port.

The MS/TP port offers optically-isolated communication. It has a removable
3-pin terminal block for the EIA-485 connection. Through this port, up to 127 devices
can be addressed¯as many as 32 on the local bus. All MS/TP baud rates are supported
from 9.6 to 76.8 kbps.

The Ethernet port offers a shielded RJ-45 connector. Through auto-negotiation and Auto-MDIX, it automatically matches its duplex setting, flow control, data rate and signal polarity to whatever is needed by the attached equipment. Therefore, no special
CAT5 cable is needed for hookup.

A resident web server allows commissioning, re-configuration and troubleshooting with a standard web browser. A reset switch is provided on the router to set the unit to factory default.

This BAS Router is priced at $295 and availability is scheduled for April 2008.
