General
DDC Data Re-programming
Additional information
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.
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 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.

Note: The alignment box has already build-in a batteries socket for
using batteries (9V) 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.
