4.9.4.2. Linking dimmer control
Dimmer control linkage is available for the display units that are connected by the RS-485 network.
The following conditions are necessary for the linkage.
1) The display units must be connected by RS-485.
2) The same dimmer control is used.
3) The display units are in the same dimmer group.
Set the details by referencing the following sections.
1) Set RS-485ID by referencing “4.9.4 1 Setting RS-485ID”.
2) Select the same dimmer unit by referencing “4.9.3 Selecting a dimmer unit”.
3) Set the display units in the same dimmer group by referencing “4.9.4.3 Setting a dimmer group”.

Available dimmer group numbers are from 1 to 10.
Set a dimmer group when the display units for which dimmer control is to be linked need to be grouped
due to the different equipment environment even though the units are connected by RS-485.
Select the same dimmer unit within the same group. Otherwise, dimmer control cannot be linked within
the group.
