ELECTRICAL CHARACTERISTICS

3.1 Analog R.G.B Input

The input signal shall be applied to the display device through a signal cable, which must be
intended as part of the monitor.
A signal connector shall be a shielded 15pin D- Sub connector and signal cable shall be Black or
White, 1.50Ў 0.05 meter long.

The interfacing method described above requires 7 input lines :

Getting Fine Picture

Step 1. At first Display, a full screen, such as, Window's background or "H" character should
be achieved by using Editor (ex: Notepad. exe)

Step 2. Adjust the screen to the center of the Display(LCD), by using the top and bottom
display controls. (i.e.Using V-Position Adjust menu)

Step 3. Adjust the screen to the center of the Display(LCD), by using the right and left
display controls. (i.e.Using Clock and H-Position adjust menu)

Step 4. Adjust the Clock-phase until the "H" Character displays clear.

Step 5. Using the Contrast. Brightness, and Color Control menu, set the color to your
preference.
Step 6. When you finish the adjustment, you can save your settings by pressing on the menu
until the OSD screen has disappeared.
Factory Setting & EEPROM Initialization Method
Factory Setting Method
- Connect the signal cable and power cable to the LCD monitor.
- Press Power switch with pressed MENU key.(Menu key + Power key).

Description
The AT24C164 provides 16,384 bits of serial electrically erasable and programmable
read only memory (EEPROM) organized as 2048 words of 8 bits each. The deviceнs
cascadable feature allows up to eight devices to share a common 2-wire bus. The
device is optimized for use in many industrial and commercial applications where low
power and low voltage operation are essential. The AT24C164 is available in space
saving 8-pin PDIP and 8-pin SOIC packages and is accessed via a 2-wire serial inter-
face. In addition, this device is available in 5.0V (4.5V to 5.5V), 2.7V (2.7V to 5.5V),
2.5V (2.5V to 5.5V) and 1.8V (1.8V to 5.5V) versions.

Notes:
1. See thermal regulation specifications for changes in output voltage due to heating effects. Load and line regulation are
measured at a constant junction temperature by low duty cycle pulse testing.
2. Line and load regulation are guaranteed up to the maximum power dissipation (18W). Power dissipation is determined by
input/output differential and the output current. Guaranteed maximum output power will not be available over the full input/
output voltage range.
