12. Adjustment of White Balance
12-1. Required Equipment
(1) Color Analyzer.(CS-100, CA-100+(CH 10), CA-210(CH 10))
* Please adjust CA-210, CA-100+ by CS-1000 before
measuring.
Color temperature standards according to CSM and Module.
White balance adjustment coordinate and color temperature.
* PC(for communication through RS-232C)
-> UART Baud rate : 115200 bps
12-2.  Connection Picture of the Measuring
Instrument(On Automatic control)
(1) Inside PATTERN is used when W/B is controlled. Connect
to auto controller or push control R/C IN-START -> Enter
the mode of White-Balance, the pattern will come out.
12-3. Auto-control interface and directions
(1) Adjust in the place where the influx of light like floodlight
around is blocked.(illumination is less than 10ux)
(2) Measure and adjust after sticking the Color Analyzer(CA-
100+, CA210) to the side of the module.
(3) Aging time : keep white pattern using inside pattern.

13. Adjustment of White Balance
(Manual white Balance)
V  
One of R Gain/ G Gain/ B Gain should be kept on 80, and
others are controlled lowering from 80
(1) Press ‘power on’ of the control R/C, set heat run to white
by pressing and heat run over 15 minutes.(Set: RS-232
Host: PC, Baud Rate: 115200bps, Download: Cortez) 
(2) Zero Calibrate CA-100+, and stick the sensor to the center
of PDP module surface when you adjust.
(3) Double click In-start key on Controlling R/C and get in
‘white balance’.
(4) Set test-pattern on and display inside pattern. Control is
carried out on three color temperature, COOL, MEDIUM,
WARM. (Control is carried out three times.)
(5) When the R/G/B GAIN is 80 on OSD, it is the FULL
DYNAMIC Range of the Module. In order to control white
balance without the saturation of FULL DYNAMIC Range
and DATA, one of R Gain / G Gain / B Gain should be kept
on 80, and other two is controlled lowering from 80.
* Color Temperature: Cool, Medium, Warm
(1) When R GAIN is set to 80
- Control G GAIN and B GAIN by lowering from 80. 
(2) When B GAIN is set to 80
- Control R GAIN and G GAIN by lowering from 80.
(3) When G GAIN is set to 80
- Control R GAIN and B GAIN by lowering from 192.
One of R Gain / G Gain / B Gain should be kept on 80, and
adjust other two lower than 80.
(When R/G/B GAIN are all 80, it is the FULL DYNAMIC
Range of Module) 
14. Input the Shipping Option Data 
1) Push the IN-START key in a Adjust Remocon.
2) Input the Option Number that was specified in the BOM, into
the Shipping area.
3) The work is finished, Push 
V
Key.
15. Set Information(Serial No& Model name)
15-1. Setting up ‘Tool OPTION1,2’
(After setting white balance, this is set)
(1) Press ADJ Key in the R/C for adjustment
(2) Insert Option value by a number key 
(3) Press the Enter Button
15-2. Check the serial number & Model Name
(1) Push the menu button in DTV mode.
- Select the SETUP-> Diagnostics -> To set.
(2) Check the Serial Number.
16. Set factoring condition
(1) This Adjustment is setting factory shipment mode.
(2) Push the IN-STOP key of adjustment remote controller
before the factory shipment.
