BACnet Networking and Setup

Setting the MAC Address:
MAC (media access control) must be UNIQUE on an MS/TP network segment within building. An installer setting up an MS/
TP segment must ensure each device has a UNIQUE MAC Address (Range 1-99). The MAC Address is set through the LCD
thermostat or LCD setup tool.
Note: Each device on a network segment must be set to run at the same speed or baud rate.

TECH TIP
24 VAC power Hot and CoMMoN polarities are critical and must not be reversed on ANY devices! reverse polarity will stop
communication on that MS/tP segment. All 24 VAC transformers must be grounded on their secondary side for BACnet to work.
NET COM wire must be connected at each device and is critical for BACnet network reliability.
Use one twisted pair for + and -, and another twisted pair for NET COM for optimal noise cancellation.
