Wiring for communications
The AppController communicates using BACnet on the following types of network segments:
MS/TP communicating at 9600 bps, 19.2 kbps, 38.4 kbps, or 76.8 kbps
ARC156 communicating at 156 kbps
NOTE For more networking details, see the Open Controller Network Wiring Installation Guide.
Wiring specifications for BACnet MS/TP and ARC156
22 AWG or 24 AWG, low-capacitance, twisted, stranded, shielded copper wire
WARNING Do not apply line voltage (mains voltage) to the controller's ports and terminals.
