04.05. BMS Configuration of ICUNO-MOD Card
Consult project system designer (BMS engineer or similar role) for the correct Modbus RS-485 configuration for this unit.
Use the DIP switches on the BMS Card to configure the Modbus parameters. New BMS configuration will take effect when the
BMS card initializes, either by the RESET button or power cycle.
04.05.01. Configure Serial Address
NOTE: The Serial Address is a number that
uniquely identifies a device on the
local RS-485 network. If two units have
the same Serial Address, identification
errors will be generated. There will be
no indication on the BMS card of any
error, however the BMS system will
not communicate with these devices.
Series Address can be any number
between 1 - 247.
