BACnet Introduction Introduction BACnet is an building automation and control networking protocol. It was developed by ASHRAE. BACnet was designed specifically to meet the communication needs of building automation and control systems. Typical applications include: heating, ventilating, and air conditioning control,BACnet MS TP Overview Manual
The BACnet MS TP protocol uses EIA 485 (RS 485) as the physical layer standard for data transmission. Neptronic Controllers also use the BACnet MS TP protocol over an RS 485 standard for communicating with third party routers, gateways, or master controllers. Wiring The communication wiring must be installed in a proper daisy chain format.RS 485 Cables | Continental Control Systems
