1. Coverage
Apply to 27” /23.8” wide monitor made in Monitor Factory(Kumi Korea) or made in accordance with the standard
of Kumi Factory process.
2. Appointment
2.1 Adjustment must be done as fixed sequence, and adjustment sequence can be modified after agreement with
the responsible R&D engineer considering mass-production condition.
2.2 Power : AC100~240 Voltage (Free)
2.3 Input signal : As Product Standard(Signal ROM : 24MB35PY/23MB35PY/22MB35Y)
2.4 WARM(6500K)-up Time : Over
than 5 minutes
2.5 Adjustment equipment : White balance equipment (CA-110/210), Display adjust equipment, VG-819(or VG828),
Oscilloscope, PC (More than 486 computer ) & White balance adjust program.,
HDCP Adjusting Jig equipment.
3. Adjustment
3.1 Overview
Use factory automation equipment and adjust automatic movement. But, do via passivity adjust in error
occurrence.
3.2 Adjustment order(refer to the Adjustment standard and adjustment command table)
3.2.1 Board Assembly
Line
 Connect input signal to 15pin D-sub.
■ Ready for adjustment : check whether adjustment command works normally or not and the
operating state of each mode.
 Check the display state of gray color when 256 gray scale pattern is embodied.
 Read by EEPROM Read Command to check whether initial value is correct or not.
3.2.2 Total Assembly Line
 Input analog signal. (1920X1080@60Hz)
 Write HDCP Key to EEPROM(24C16) by using DDC2AB protocol & HDCP Adjusting Jig
equipment [ Address 0xAC 80, 289 bytes ]
 If error is occurred, write and check again.
 Ready : Heat-run during 30 minutes in the state with signal
 Connect input signal to D-sub.
 Default value before adjustment : Contrast “70” , Brightness “100(Max)”
3.2.3 Adjustment of Horizontal/Verticality screen position, Clock and Clock Phase at each Mode.
■ There is no spe
cial factory mode adjustment.
Writing initial value of EEPROM in Board Assembly line is adjusting Preset Mode and Reset
mode. (EEPROM is initialized when AC Power is ON first.)
■ If the change of FOS data is needed after M.P, it is possible by writing Mode Data with
EEPROM write command or modifying the Mode Data in MICOM itself.
