CONTROL
Step 4: System Setting of Centralized Controller
SYSTEM SETTING includes ADDRESS SETTING and INITIALIZE SETTING. The former one is used for setting
address of control object (communication module), and the latter one for initializing the data in the centralized controller
(including clear all the finished address settings).
Since the centralized controller can control at most 64 communication modules and the address of them is 0 to 253
(0 is generally unused), it must specify the address of communication module needed to be controlled. It is ADDRESS
SETTING, which is not recommended to operate by users.
The debugging personnel can press SYSTEM/DEBUG into system setting interface. After pressing UP, DOWN,
LEFT or RIGHT button, press CONFIRM button into the interface for selection between ADDRESS SETTING and
INITIALIZE SETTING.
The operation procedure of ADDRESS SETTING:
1) The centralized controller without energizing and setting will display following.

Press SYSTEM/DEBUG into system setting interface. After pressing UP, DOWN, LEFT or RIGHT button, press

Hard address
Soft address
Press LEFT or RIGHT button to switch between SOFT and Hard ADDRESS settings, and UP or Down button to
adjust their values.After adjustment, press CONFIRM button to make the address values corresponding and effective.
If the cursor stops at hard address position (hard address is blinking), press CANCEL button to make the setting value
ineffective, in which case, the “- -”will be displayed.(Soft address is the No. displayed in 1-64 grid of LCD and hard
address is the actual one of communication module.)
In this example, the centralized controller controls 3 communication modules with the address of 01, 02 and 03 (i.e.
hard address is 01,02 and 03).For convenient management, soft address will be set to the same as hard address, i.e. “01
001”, “02 002”and “03 003”.
