4.6.5 DVI-PC
4.6.5.1
Select input DVI model 112(1440*900@60hz), 64 Gray
Scale pattern and whether picture is displayed or not
4.6.6 HDMI-DTV
4.6.5.1
Select input HDMI model 112(1080i), 64 Gray Scale
pattern and whether picture is displayed or not
4.7 DPM operation confirmation
Check if Power LED Color and Power Consumption
operate as standard.
Set Input to RGB and connect D-sub cable to set
• Measurement Condition : 230V@ 50Hz (Analog)
• Confirm DPM operation at the state of screen without
Signal
4.8 HDCP(High-Bandwidth Digital Contents Protection)
SETTING
• Connect D-sub Signal Cable to D-Sub Jack
• Input HDCP key with HDCP-key- in-program
• HDCP Key value is stored on EEPROM(AT24C64)
which is E00~F20 addresses of 0xBC~0xBE page
• AC off/ on and on HDCP button of MSPG925 and
confirm whether picture is displayed or not of using
MSPG925
• HDCP Key value is different among the sets.
4.9 Outgoing condition Configuration
• After all function test., press IN-STOP Key by SVC
Remote controller. And make Outgoing Condition.
• When pressing IN-STOP key by SVC remocon, Green
and red LED are blinked alternatively. And then
automatically turn off. (Must not AC power OFF during
blinking)
4.10 internal pressure
• Confirm whether is normal or not when between power
board's ac block and GND is impacted on 1.5kV(dc) or
2.2kV(dc) for one second

• EDID write : 16-byte by 16-byte, 8 order (128-byte)
write(TO “00 – 7F” of “EEPROM Page A4”)
• FOS Default write : 16-mode data
(HFh,HFl,VF,STD,HP,VP,Clk,ClkPh,PhFine) write
• Random Data write : write the appointment Address of
E2PROM
5.4 VRAM Read
• Send CMD(70h) to read Video RAM value from MICOM
And save its value to 128-Bytes Buffer(Common Buffer
for the use of EDID)
• Delay 500ms ( Time to Wait and Read Video RAM from
MICOM)
• Be transmitted the contents of MICOM’s 128-bytes
Buffer to PC.
(128th Data is the CheckSum of 127-bytes data : That’s
OK if the value of adding 128-bytes Data is Zero)
