SHEET BAS Router — BACnet® Multi-Network Router The BAS Router provides stand-alone routing between BACnet networks such as BACnet/IP, BACnet Ethernet, and BACnet MS/TP — thereby allowing the system integrator to mix BACnet network technologies within a single BACnet internetwork. The BAS Router has two physical communication ports. One is a 10/100 Mbps Ethernet port and the other is an optically isolated MS/TP port. Router configuration is accomplished via a web page. Versatile Routing Between … • BACnet/IP and BACnet MS/TP • BACnet Ethernet and BACnet MS/TP • BACnet/IP and BACnet Ethernet • BACnet/IP and BACnet Ethernet and BACnet MS/TP • Two BACnet/IP networks IP Network Support • Web server for commissioning and troubleshooting • Communication diagnostic web page • BACnet/IP Broadcast Management Device (BBMD) • Foreign Device Registration (FDR) Flexible Communications • 10/100 Mbps Ethernet with auto-negotiation and Auto-MDIX • Optically isolated MS/TP port • MS/TP baud rates range from 9.6–76.8 kbps • Jumper-selectable MS/TP bias and termination Convenient Installation • 24 VAC/VDC (± 10%), 47–63 Hz input voltage • Din-rail mounted BASautomation CONTROLS

Data Sheet — BAS Router BAS Router — BACnet® Multi-Network Router The BAS Router is housed in a metal case that mounts on 35-mm DIN-rail and is powered from a 24 VAC/VDC (± 10%) source. There is one MS/TP port and one 10/100 Mbps Ethernet port. The MS/TP port offers an optically-isolated transceiver. It has a removable 3-pin terminal block for the EIA-485 connection. Logically, 255 devices can be addressed, but physically, the number of devices depends upon device loading. Up to 31 full-load EIA-485 devices can share the same MS/TP bus segment as the BAS Router. For half-load devices, there can...

Data Sheet — BAS Router BAS Router Parameters Main Settings Device Parameters Default Value Description Device Name BASRT-Bxxxxxx The unique default value ends with the last 6 characters of the unit’s Ethernet MAC address. You can edit it to be up to 20 characters. Device Instance 0 The router device instance is a 22-bit decimal value (0–4,194,303). Each BACnet device has a unique device instance. BACnet Ethernet Parameter Default Value Description BACnet Ethernet Network 0 BACnet/IP Parameters 16-bit decimal value (1–65534). Each BACnet network, regardless of technology, must have a unique network...

BBMD UDP Port Primary Normally the primary port is selected. The secondary port is used in very special applications. Accept FDR Checked Secondary BACnet/IP UDP Port 0000 Uncheck to disable foreign devices from registering with this router. Enter secondary UDP port as a 16-bit hex value (0-FFFF) when operating with two BACnet/IP BACnet networks. In this case use BAC1 if it is available. Secondary BACnet/IP Net...

Data Sheet — BAS Router Wiring Diagrams Since the BAS Router incorporates a half-wave rectifier circuit, it can share the same 24 VAC power with other half-wave rectified devices. It can also be powered from a 24 VDC source. A redundant power connection exists for back-up power schemes. The BAS Router incorporates a 3-wire optically-isolated EIA-485 interface for the MS/TP connection, allowing better circuit protection and noise immunity. To connect to other 3-wire devices simply make a one-to-one connection to the other devices. But when connecting to 2-wire non-isolated devices, the signal...
