3-2. COMPONENT input ADC
3-2-1 Component Gain/Offset Adjustment
• Convert to Component in Input-source
I2C COMMAND: 0xF4 (SELECT_INPUT) 0x00 0x40
(COMPONENT)
cf. 0x10(TV), 0x20(AV), 0x40(COMPONENT), 0x60(RGB),
0x90(HDMI)
• Signal equipment displays
Impress Resolution 480i
MODEL : 209 in Pattern Generator (480i Mode)
PATTERN : 08 in Pattern Generator( MSPG-925 SERISE)
• Adjust by commanding AUTO_COLOR_ADJUST(0xF1)
0x00 0x02 instruction
• Signal equipment displays
Impress Resolution 1080i
MODEL : 223 in Pattern Generator(1080i Mode)
PATTERN : 08 in Pattern Generator( MSPG-925 SERISE)
• Adjust by commanding AUTO_COLOR_ADJUST(0xF1)
0x00 0x02 instruction
*Manual ADC process using Service Remocon. After enter
Service Mode by pushing “ADJ” key,
Execute “ADC Adjust” by pushing “G” key at “ 0. ADC
CALIBRATION ”.
3-2-2 Confirmation
• We confirm whether “0xBF(480i)/0xC8(1080i)” address of
EEPROM “0xA2” is “0xAA” or not.
• If “0xBF(480i)/0xC8(1080i)” address of EEPROM “0xA2”
isn’t “0xAA”, we adjust once more
• We can confirm the ADC values from “0xB9~0xBE(480i)/
0xC2~(1080i)” addresses in a page “0xA2”
*Manual ADC Confirmation using Service Remocon. After
enter Service Mode by pushing “INSTART” key,
