Display Data Channel
The DDC2B/2Bi function belongs to IC101 (microcomputer).
DDC2B: Immediately after the monitor power is turned ON, the microcomputer reads the EDID
data from IC104. It outputs the EDID data according to the clock input into pin 34 SCL-DDC.
DDC2Bi: The monitor adjusts the picture etc. corresponding to DDC2Bi command which is
input to pin 34 SCL-DDC and pin 35 SDA-DDC of microcomputer. This DDC2Bi command is
used for the adjustment operated at factory. In case general user uses this, he/she needs
specified application and adapter.

LED
J102 pin 1 is connected to the anode of the green LED, J100 pin 2 is connected to the anode
of the amber LED, and pin 6 is connected to the cathodes of both. Since 5V is
normally supplied, the current flows to J102 pin 1 to turn OFF Q100. Therefore, any current
does not flow to J102 pin 2.
(The green LED only is lit.)
Since 5V is turned OFF in the power management mode, no current is not flowed to
J102 pin 1 to turn ON Q100. Therefore, the current flows to J102 pin 2. (The Orange LED only
is lit.)
