VGA Analog PC/RGB, enabling digital sources to connect with any display, pro-  
jector or TV using VGA. Output resolutions up to 1920x1200 are supported. The

is sent to the source for compatibility.

the VGA output connector. Connect the supplied 5V DC power supply to the unit  
and connect the included AC power cord to an available electrical outlet.

EDID MANAGEMENT  
EDID Modes  
1. EXTERNAL MODE:  
In order to use the external (display) EDID, the DVI to VGA Converter must  
be powered after it has been connected to the display. If the Converter is  
powered before it is connected to the display, then the internal EDID will be  
used.  
2. INTERNAL MODE:  
The internal EDID is a preset EDID that is stored in the DVI to VGA  
Converter. This pre-programmed standard EDID data structure is compatible  
with most A/V displays. All resolutions and audio formats specied in  
the internal EDID will be passed to the source device. See page 8 for a  
complete listing of the resolutions and audio formats listed in the internal  
EDID.
