LCD : Color Analyzer ( CA-110), PDP : Color Analyzer (CA-100)
CA-210 : The both of LCD and PDP are available.

Notice : When using the Color Analyzer with PDP, recommend
the CA-100 more than CA-210.

If CA-100 can not available, it is also good to use the CA-210.
PC (for communication through RS-232C) => UART Baud rate :
115200
Pattern Generator (MSPG-925FA etc. )

• Color Temperature & Color Coordinates Setting

When adjusting the Color Temperature of LCD, Color
AnalyzerCA-210(Matrix should be corrected through CH9 of
CS-1000) should be used.
When adjusting the Color Temperature of PDP, Color
AnalyzerCA-210(Matrix should be corrected through CH10 of
CS-1000) should be used. When CA-210 have used, it don’t
need to fit the CH10.
Adjust the Color Temperature based below adjustment color
coordinates.
Even if CH9 of CA-210 is corrected with Matrix, there may be
many character of Module and Filter.
Therefore Refer to the below Color Coordinates Target.

But, in case of WCG module, use the CH12 of CA-210.
