Inside PATTERN is used when W/B is controlled. Connect to
auto controller or push Adjustment R/C POWER ON ->
Enter the mode of White-Balance, the pattern will come out

RS-232C Communication
* Auto-control interface and directions
1) Adjust in the place where the influx of light like floodlight
around is blocked. (illumination is less than 10 lux).
2) Adhere closely the Color Analyzer (CA210) to the module
less than 10cm distance, keep it with the surface of the
Module and Color Analyzer's Prove vertically.(80~100°).
3) Aging time
- After aging start, keep the power on (no suspension of
power supply) and heat-run over 15minutes.
- Using 'no signal' or 'full white pattern' or the others,
check the back light on.

In the SET applied LED module, as to physical characteristics
of LED Module, the sets takes a 120 minutes by aging time to
stabilize a color coordinates. So White Balance Control
equipments get the SET Aging Time from SET and then going
to control the W/B by revise color coordinates in the each time
