Adder Technology DDC Ghost Leaflet

Link the computer 
to the BLUE 
connector

The DDC Ghost module contains a default set of EDID values which 
may be used immediately with most monitors (see Standard EDID 
Information). Alternatively, you can use a ‘donor’ monitor from which 
you can clone new EDID information.

1  Link the BLACK connector of the DDC Ghost to the donor monitor 

(diagram A).

2  Provide power for the DDC Ghost module in one of two ways, either:

•  Link the BLUE connector of the DDC Ghost to a computer video 

output for the duration of the cloning operation (diagram B), or

•  Attach the optional 5VDC power adapter to the socket on the side 

of the DDC Ghost module (diagram C).  

3  Ensure that the donor monitor and the DDC Ghost module are 

powered. The DDC Ghost red STATUS indicator should be on.

4  Using a narrow implement, press and hold the recessed button 

labelled CLONE on the side of the module (diagram D). The STATUS 
indicator will begin to flash slowly for five seconds. Release the 
button while the indicator is still slowly flashing.
•  If new EDID information is available, it will be copied to the DDC 

Ghost module memory.

•  If there is no EDID information to clone then the existing DDC 

Ghost memory will be not altered.

•  If there is an error during cloning then the DDC Ghost will be 

automatically reset to its standard values.  

5  When the operation is complete, the STATUS indicator will flash 

rapidly five times. Disconnect the DDC Ghost module from the donor 
monitor. 

If required, you can reinstate the standard EDID values (see Standard 
EDID Information) into the DDC Ghost module memory. 

1  Ensure that the DDC Ghost is powered (either from the video output 

of a host computer or an optional power adapter) and check that the 
red STATUS indicator is on.

2  Using a narrow implement, press and hold the recessed button 

labelled CLONE on the side of the module (diagram D). The red 
STATUS indicator will flash slowly for five seconds and then will go 
off for a further five seconds.

3  Release the button while the red STATUS indicator is off, following 

the five slow flashes. The reset operation will take place and then 
the red STATUS indicator will flash rapidly five times to indicate a 
successful completion.

Link the monitor 
to the BLACK 
connector

If power is 
unavailable from 
the computer via the 
BLUE connector, use 
the optional 5VDC 
power adapter 

Press and hold the 
recessed CLONE button.
Release it as follows:
To clone: While 
indicator is slowly 
flashing.
To reset: While 
indicator is off 
(immediately following 
the slow flashes).   

During normal operation, the DDC Ghost module supplies either 
standardised or cloned EDID information to the computer instead of 
the data from the connected monitor. 

1  Link the BLACK connector of the DDC Ghost to the monitor 

(diagram A).

2  Link the BLUE connector of the DDC Ghost to the computer 

video output (diagram B)

  Note: In operation, the red STATUS indicator should be on. If 

it is not then power is not being correctly supplied from the 
computer (pin 9 of the VGA connector). If this situation cannot 
be resolved, attach the optional 5VDC power adapter to the 
socket on the side of the DDC Ghost module (diagram C).  

3  Switch on the computer and monitor in the normal manner.

The standard EDID information supplied within the DDC 
Ghost module represents a standard analogue monitor 
(with no manufacturer details) capable of resolutions up to 
1600x1200@60Hz. Other presented information is as follows:
