Master-Slave Communication Method
There are two modes for Master-slave structure.
Global Control communication
The Master unit will broadcast the settings to all slave units. During normal operation, slave units can receive commands from
its local wireless handset and wall pad control panel. Upon reception of master global commands, all slave unit settings will be
replaced by the master settings.
Addressable communication
The Master controller must be the LCD wall pad. Slave unit parameters are set as usual. Upon receiving the control commands
from a master, the addressed slave unit settings will be replaced by the master settings.
DIPA-S1 address setting: ON=1, OFF=0.

If the master unit is equipped with a wireless handset only, it can only use the Global-Control communication method. If it is
equipped with a wall pad, it can use both communication methods.
