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
to be re-programmed "Analog DDC IC, Digital DDC IC & EEPROM".
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)
B. Running " io.exe" everytime, Before you start to programming
edid data .
3. EDID46.EXE program
4. A/D Alignment kits (12NC: 3138 106 10396):
inclusion : a. Alignment box x1 (Fig. 2)
b. Printer cable x1
c. (D-Sub) to (D-Sub) cable x1
d. (D-Sub) to (DVI) cable x1
C:\WINDOWS\system32\drivers(winXP)
8. Alignments
Note: The alignment box has already build-in a batteries socket for
using batteries (8~12V) as power source. Pull out the socket by
remove four screws at the rear of box. Please do not forget that
remove batteries after programming. The energy of batteries can
only drive circuits for a short period of time.
