DDC Data Re-programming
In case the DDC data memory IC or main EEPROM which storage all
factory settings were replaced due to a defect, the serial numbers have
Analog DDC IC, & EEPROM
to be re-programmed"
It is advised to re-soldered DDC IC and main EEPROM from the old
board onto the new board if circuit board have been replaced, in this
case the DDC data does not need to be re-programmed.
Additional information
Additional information about DDC (Display Data Channel) may be
obtained from Video Electronics Standards Association (VESA). Extended
Display Identification Data(EDID) information may be also obtained from
VESA.
System and equipment requirements
1. An i486 (or above) personal computer or compatible.
2. Microsoft operation system Windows 95/98 .
Y ou have t o Install the EDID_PORT_Tool under Win2000/XP . As
Fig. 1 .
A. Cody the "UserPort.sys" to C:\WINNT\system32\drivers(win2000)
C:\WINDOWS\system32\drivers(winXP)
B. Running " io.exe" everytime, Before you start to programming
edid data .
3. EDID301.EXE program .
4. A/D Alignment kits (12NC: 3138 106 10079) shown as Fig. 2:
inclusion : a. Alignment box x1
b. Printer cable x1
c. (D-Sub) to (D-Sub) cable x1
Note: The EDID46.EXE is a windows-based program, which cannot be
run in MS-DOS.

Configuration and procedure
There is no Hardware DDC (DDC IC) anymore. Main EEPROM stores
all factory settings and DDC data (EDID code) which is also called
Software DDC. The following section describes the connection and
procedure for Software DDC application. The main EEPROM can be re-
programmed by enabling '' factory memory data write'' function on the
DDC program (EDID301.EXE).
Initialize alignment box
Fig. 1
In order to avoid that monitor entering power saving mode due
to sync will cut off by alignment box, it is necessary to initialize
alignment box before running programming software
(EDID301.EXE). Following steps show you the procedures and
connection.
Step 1: Supply 8-12V DC power source to the Alignment box by
Step 2: Connecting printer cable and D-Sub cable of monitor as Fig. 3
