CONTROL UNIT MODBUS ADDRESSING
When more than one Control Unit is connected on a system, the Modbus address must be set up in each
Control Unit before the system will communicate correctly with a Remote Display Unit.
NOTE: For multiple Control Units per system, each Control Unit must have its own Modbus
address and they must be sequential
All Control Units are configured with a Modbus address 01 (1

There are 2 methods to change the Modbus address, the first is via the Membrane (refer Section 2.10.1),
