OPERATING THE MONITOR 45
[SUPPLEMENTAL INFORMATION OF THE AUTO BRIGHTNESS FUNCTION]
To control multiple monitors collectively
In such a case where the tiling function is used, you can control the auto brightness function by
sharing the detection result of the brightness sensor of a certain monitor among the connected
monitors.
1. Multi-connect the monitors using RS-232C cables (commercially available) as shown by the
example below.
Master: Monitor configured as Master
that detects the outside light
(Monitor ID is “1”.)
Slave: Monitor controlled by the
Master monitor (Monitor ID is
other than “1”.)
2. Assign a monitor ID to each multi-connected monitors using MONITOR ID. (See page 38.) Monitor
ID is selectable from 1 to 26. The monitor ID of the Master monitor should be “1” and those of
the Slave monitors should be other than “1”. You are recommended to assign IDs to the monitors
consecutively from 1, 2, 3, and on.
3. Set AUTO BRIGHTNESS on the OSD screen (PICTURE) as follows.

To use a computer to control the monitors
When using a computer to control the monitors, you must prepare an application software program
for control by yourself. Brightness of all the monitors can be controlled centrally using a computer, if
the customer create a control application to remotely read the value from two brightness sensors of
any monitor and distribute it to all monitors.
1. Connect the RS-232C IN connector of the Master monitor shown above and the RS-232C
connector of the computer using an RS-232C cable. The communication control function via LAN
isn’t supported on the monitor alone, however, it is available when the monitor is used with the
computer.
2. Assign a monitor ID to each multi-connected monitors using MONITOR ID. (See page 38.)
Monitor ID is selectable from 1 to 26.
3. Set AUTO BRIGHTNESS on the OSD screen (PICTURE) as follows.

4. A control application made by the customer reads the value from two brightness sensors of any
monitor and distributes it to all monitors. For the specifications of the communication commands,
contact your dealer.
