DDC Instructions
1. General
DDC Data Re-programming
In case the main EEPROM with Software DDC which store all factory
settings were replaced because
a defect,repaired monitor the serial
numbers have to be re-programmed.
it is advised to re-soldered the main EEPROM with Software DDC 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 aiso
obtained from VESA.

4. Configuration and procedure
There is no Hardware DDC (DDC iC) anymore. Main EEPROM stores
all factory settings and DDC data (EDID code) which is so called
Software DDC. The following section describes the connection and
procedure for Software DDC application. The main EEPROM can be re-
probrammed by enabling "factory memory data write" function on the
DDC program (EDID301.EXE).
*** INITIALIZE ALIGNMENT BOX ***
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 re-programming DDC Data. Following steps
show you the procedures and connection.
Step 1: Supply 8~12V DC power source to the Alignment box by
plugging a DC power cord or using batteries.
Step 2: Connecting printer cable and video cabie of monitor as
shown in Fig.3.
