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 10ux).
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.
