Video Adapter Board Header Signals
The following table defines the pin signals of the non-standard VGA header on the video adapter board. This
appendix does not define the industry-standard SDVO connector on the board. See Table 2-2 on page 11 for
more SDVO connector information.
Table B-1 lists the signals and their descriptions for the J2 VGA interface, which provides a shrouded,
12-pin right-angle header with odd/even (1, 2) pin sequence, and 0.079" (2mm) pitch (Adam Tech 2BRH).
Note: The shaded table cells denote power or ground.
