Wiring the UC Open XP to the MS/TP network

The UC Open XP communicates using BACnet on an MS/TP network segment communications at 9600 bps,
19.2 kbps, 38.4 kbps, or 76.8 kbps.
Wire the controllers on an MS/TP network segment in a daisy-chain configuration.
Install a BT485 on the first and last controller on a network segment to add bias and prevent signal
distortions due to echoing.
See the MS/TP Networking and Wiring Installation Guide for more details.
