Adder Technology DDC Ghost Cloning EDID information, Resetting EDID information, Note The DDC

Cloning EDID information

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.

To clone EDID information

1Link the BLACK connector of the DDC Ghost to the donor monitor (diagram A).

2Provide 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).

3Ensure that the donor monitor and the DDC Ghost module are powered. The DDC Ghost red STATUS indicator should be on.

4Using 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.

5When the operation is complete, the STATUS indicator will flash rapidly five times. Disconnect the DDC Ghost module from the donor monitor.

Resetting EDID information

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

To reset the EDID information

1Ensure 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.

2Using 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.

3Release 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 computer to the BLUE 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).

Installing for normal operation

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.

To install for normal operation

1Link the BLACK connector of the DDC Ghost to the monitor (diagram A).

2Link 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).

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

Standard EDID information

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:
