Daisy Chaining
Daisy chaining several units is possible. The distance between the units should not exceed 50m. The units do not
boost the signal. The total length of the chain should not exceed 150m. A signal repeater is recommended if the
installation exceeds this length.
Master/Slave Configuration
Master and slave configuration is not possible. The BMS signal must be sent to each address not just the first in
line.
PLEASE NOTE:
It is possible to connect the unit to the BMS and the unit controller simultaneously.
Neither system has priority over the other. The sequence of control and speed of communication will determine
priority of the control signal.
For control of the unit at least the BMS or one wired touchscreen controller is required.
If the default Modbus settings are changed the unit must be turned OFF on the MAINS and connected once
again for the changes to take effect.
