4. Manual Adjustment
4.1. ADC(Saturn5) Adjustment
4.1.1. Overview
ADC adjustment is needed to find the optimum black level and
gain in Analog-to-Digital device and to compensate RGB
deviation.
4.1.2. Equipment & Condition
(1) Adjust Remote control
(2) 801GF(802B, 802F, 802R) or MSPG925FA Pattern
Generator
- Resolution :
480i Comp1(MSPG-925FA : Model-209, Pattern-65)
1080p Comp1(MSPG-925FA : Model-225, Pattern-65)
1080p RGB (MSPG-925FA : Model-225, Pattern-65)
- Pattern : Horizontal 100% Color Bar Pattern
- Pattern level: 0.7 ± 0.1 Vp-p
- Image
(3) Must use standard cable
4.1.3. Adjust method
(1) ADC 480i/1080p Comp1, RGB
1) Check connected condition of Comp1 cable to the equipment.
2) Give a 480i, 1080p Mode, Horizontal 100% Color Bar
Pattern to Comp1.
(MSPG-925FA -> 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 1080p on the menu.
5) Press OK in Comp480i menu.
6) Give a 1080p Mode, Horizontal 100% Color Bar Pattern
to Comp1. (MSPG-925A -> Model: 225, Pattern: 65)
7) Press OK in Comp 1080p menu.
8) Press OK in RGB menu.
9) If ADC Comp is successful, “ADC Component Success”
is displayed. If ADC calibration is failure, “ADC
Component Fail” is displayed.
10) If ADC calibration is failure, after recheck ADC pattern
or condition, retry calibration
11) If ADC RGB is successful, “ADC RGB Success” is
displayed. If ADC calibration is failure, “ADC RGB Fail”
is displayed.
12) If ADC calibration is failure, after recheck ADC pattern
or condition, retry calibration
4.2. EDID(The Extended Display Identification
Data)/DDC(Display Data Channel) download
(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
- Adjust remote control
- Since embedded EDID data is used, EDID download JIG,
HDMI cable and D-sub cable are not need.
(3) Download method
1) Press Adj. key on the Adj. R/C,
2) Select EDID D/L menu.
3) By pressing Enter key, enter EDID D/L menu.
4) If Download is successful, OK is displayed, but If
Download is failure, NG is displayed.
5) If Download is failure, Re-try download.
(4) EDID DATA
