9-3. Manual W/B Process
(Using adjusts Remote control)
(1) After enter Service Mode by pushing “ADJ” key.
(2) Enter White Pattern off of service mode, and change
(2) Enter White Pattern off of service mode, and change
off -> on.
(3) Enter “W/B ADJUST” by pushing “
G

the mode of White-Balance, the pattern will come out.
9-5. 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
- After ajing start, keep the power on(no suspension of
power supply) and heat-run over 15minutes.
- keep white pattern using inside pattern.

Command form use DDC2AB standard communication
protocol.
1. LEN : DATA BYTE number to send.
2. CMD : Command language that monitor executes.
3. VAL : FOS DATA
4. CS : Dada’s CHECKSUM that transmit.
5. DELAY : 50MS
6. A : Acknowledge.
