16.3 Changing DOM Node Addresses
The rotary encoder on the PCB can be used to change the node address of the data output modules if required when
using the MODBUS output.
The factory setting of the node address is 1 (position 0).
For instance, if there are multiple systems in the building and all of the data output modules are connected to the
building management system, then each of the data output module will require their node address changing so the
building management system can communicate correctly with them via MODBUS.

MODBUS RTU CONNECTIONS
MODBUS connections to a building management system can be made via a RS485 link to the COM, A & B.
NOTE: J3 IS USED TO LINK IN THE BUS TERMINATION RESISTOR. THIS
LINK IS TO BE FITTED IF THIS MODULE IS THE END NODE ON THE RS485 BUS.
