(2) Confirmation

1) We confirm whether “0xBF(480i)/0xC8(1080i)” address

of EEPROM “0xA2” is “0xAA” or not.

2) If “0xBF(480i)/0xC8(1080i)” address of EEPROM “0xA2”

isn’t “0xAA”, we adjust once more.

3) We can confirm the ADC values from “0xB ~0xBE(480i)/

0xC2~(1080i)” addresses in a page “0xA2”.

* Manual ADC Confirmation using Service Remocon. After

enter Service Mode by pushing “INSTART” key.

5. Manual Adjustment

5.1. ADC(Saturn5) Adjustment

(1) Overview

ADC adjustment is needed to find the optimum black level
and gain in Analog-to-Digital device and to compensate
RGB deviation.

(2) Equipment & Condition

1) Adjust Remocon
2) 801GF(802B, 802F, 802R) or MSPG925FA Pattern

Generator

- Resolution: 480i, 1024*768
- Pattern : Horizontal 100% Color Bar Pattern
- Pattern level: 0.7±0.1 Vp-p
- Image

3) Must use standard cable

(3) Adjust method

• ADC 480i Comp1

1) Check connected condition of Comp1 cable to the

equipment

2) Give a 480i Mode, Horizontal 100% Color Bar Pattern

to Comp1.

(MSPG-925FA Ë Model: 209, Pattern: 65)

3) Change input mode as Component1 and picture mode

as “Standard”

4) Press the In-start Key on the ADJ remote after at least

1 min of signal reception. Then, select 7. External ADC
-> 1. COMP 480i on the menu. Press enter key. The
adjustment will start automatically.

5) If ADC calibration is successful, “ADC RGB Success”

is displayed.

If ADC calibration is failure, “ADC RGB Fail” is
displayed.

6) If ADC calibration is failure, after recheck ADC pattern

or condition retry calibration. Error message refer to (v)

• ADC 1024*768 RGB

1) Check connected condition of Component & RGB

cable to the equipment

2) Give a 1024*768 Mode, 100% Horizontal Color Bar

Pattern to RGB port.

(MSPG-925 Series Ë model:60 , pattern:65 )

3) Change input mode as RGB and picture mode as

“Standard”

4) Press the In-start Key on the ADJ remote after at least

1 min of signal reception. Then, select 7. External ADC
-> 1. COMP 480i on the menu. Press enter key. The
adjustment will start automatically.

5) If ADC calibration is successful, “ADC RGB Success”

is displayed.

If ADC calibration is failure, “ADC RGB Fail” is
displayed.

6) If ADC calibration is failure, after recheck ADC pattern

or condition retry calibration

Error message refer to 5)

5.2. EDID(The Extended Display Identification

Data)/DDC(Display Data Channel) download

Reference : Download is only possible in POWER ONLY

MODE

(1) Overview

It is a VESA regulation. A PC or a MNT will display an
optimal resolution through information sharing without any
necessity of user input. It is a realization of “Plug and Play”.

(2) Equipment

- Since embedded EDID data is used, EDID download JIG,

HDMI cable and D-sub cable are not need.

- Adjust remocon

(3)Download method

1) Press Adj. key on the Adj. R/C,
2) Select EDID D/L menu.
3) By pressing Enter key, EDID download will begin
4) If Download is successful, OK is display, but If

Download is failure, NG is displayed.

5) If Download is failure, Re-try download.

Caution) When EDID download, must remove RGB/HDMI cable.
