Hi, I just ordered 10 CO2-N’s to run with the T3-Nano’s to provide BACnet points to a few other network devices and loggers. I have connected via the Nano through the Modbus tool, and tried to set it up for bacnet (3=bacnet) but i cant seem to connect through them via bacnet. Is there a full document for proper configuration somewhere?
Make sure RS485 port on T3-Nano is set to BACnet MS/TP and baud rate matches CO2-N.
Also check for “ID collisions”. If two devices share the same MS/TP ID, communication will fail. In T3000 → T3-Nano → Communication, open “Network Health”, any collisions will show up there.
