The BAS Router routes messages between BACnet/IP and BACnet MS/TP networks as per the ANSI/ASHRAE 135 (ISO 16484-5) standard. It allows BACnet/IP devices connected over Ethernet to communicate with MS/TP devices. The router mounts on 35-mm DIN-rail and is powered from a 24 VAC/VDC source. Each unit contains one MS/TP port and one 10/100 Mbps Ethernet port. The router is configurable via its webpage.
The MS/TP port offers an optically-isolated transceiver. 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 31 full-load devices 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, data rate and signal polarity to whatever is needed by the attached equipment. Therefore, any CAT5 cable can be used 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 the factory default IP address.
Three LEDs are provided: The power LED glows green when proper power is provided. A bi-color Ethernet LED glows green for 100 Mbps operation and yellow for 10 Mbps and indicates activity by flashing. A green LED flashes when MS/TP traffic is received.
Each unit complies with Class A radiated and conducted emissions as defined by EN55022 and CFR 47, Part 15.
