BACnet Communication Errors
1. BACnet MS/TP is based on a RS-485 network. It must be wired in a daisy chain
configuration. A daisy chain means that there is only one main cable, and every network
device is connected directly along its path.
Do not use Star, Bus, “T” or any other type of network configuration. Any of these other
network configurations will result in an unreliable network and will make troubleshooting
difficult.
Correct polarity is imperative on MS/TP wiring. Always ensure that the positive terminal on a
device has the same color wire connected to it throughout the network and same for the
negative terminal, e.g. two wire conductor with black and white wire – black to the positive
terminal and white to the negative terminal. Keep this consistent throughout the network.
2. The network should be terminated twice: once at the beginning and again at the end of
each run. This is strongly recommended.
The network speed or baud rate must be the same throughout the network.
NOTE:
The default speed for Antec Controls BACnet MS/TP controls is 76,800. BACnet
MS/TP currently supports 4 standard speeds which are: 9,600, 19,200, 38,400, 76,800.
3. Binary address must be unique for each device on the network. No two devices can have
the same address. This includes if you are incorporating an Antec Controls product onto an
existing network. Determine the existing addressing scheme for the existing network. The
address is set using the Network service menu.
4. Ensure all connected devices are programmed with the predetermined device instances
and mac addresses. If devices are not addressed correctly, then they will not display on the
MVM or will display in the incorrect location.
MVM screen not clearly visible (dim).
Adjust the brightness setting in the
Info section of the Setup Menu.
MVM screen goes black when MS/TP wiring is
connected.
Check the polarity of the power wiring on the bottom of the MVM.
