Dual Mode DisplayPort
The DP DA2 supports dual mode for interoperability with VGA, DVI, and HDMI display devices. Appropriate adapters are required.
NOTES:
•Certain VGA displays that lack a scaler do not work properly with Dual Mode DisplayPort.
•In some applications using DisplayPort adapters, the DP DA2 may be unable to capture EDID of the display connected to output 1. Use SIS commands to adjust the DDC speed (see page 15).
EDID Minder
During boot up, the source device uses the auxiliary channel to obtain Extended Display Identification Data (EDID) from the display device. This allows the output signal to match the resolution and refresh rate of the display device.

EDID Minder allows the user to store and use EDID values for another
display device to ensure the output signal is compatible with both the display devices.

Recording EDID
1.Connect the display device that will provide EDID information to output 1.
2.Power on the display and the DP DA2.
3.Set DIP switch 1 in the Stored (down) position (see the “DIP Switches” section on the following page for more information). The EDID Minder LED lights red until you start recording EDID.
4.Press the EDID Store push button. The button is recessed (you may need a small screw driver).
The EDID Minder LED lights amber while the EDID is being stored and turns green when the recording process is successfully completed.
EDID information is read from the display device connected to output 1. The recorded EDID is stored in
The new EDID is then available with DIP switch 1 is in the Stored position. Each time a new EDID is recorded, it overwrites the existing data and is available when DIP switch 1 is in the Stored position.
NOTE: If the EDID for a display device is corrupted or cannot be read, the DP DA2 will continue to use the currently stored EDID.
EDID Minder LED
The LED shows the status of the EDID recording process:
•Off — DIP switch 1 is set to Default.
•Red — DIP switch 1 is set to Stored, but external EDID has not been stored (the factory default EDID is still present).
•Amber — New EDID information is currently being read and stored.
•Green — External EDID has been stored.
