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.
2. Assign a monitor ID to each multi-connected MDT552S using MONITOR ID. (See page 54.)
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.
AUTO BRIGHTNESS CONTROL
Master monitor LOCAL PRIMARY
Slave monitors REMOTE SECONDARY
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 MDT552S using MONITOR ID. (See page 54.)
Monitor ID is selectable from 1 to 26.
3. Set AUTO BRIGHTNESS on the OSD screen (PICTURE) as follows.

Master monitor REMOTE SECONDARY
Slave monitors REMOTE SECONDARY
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 specifi cations of the communication commands, contact your dealer.
