Video 13-7
13.05 VIDEO FEATURE CONNECTOR (J11)
The Video Feature Connector (also called a Dynamic Overlay Port) at J11 is a
VESA/VGA pass-through connector. It directly supports the 8-bit mode; the connector
also supports the 16-bit mode when using an external data multiplexer.
Through the Video Feature Connector, the TEK933 makes possible dynamic overlay.
In dynamic overlay configurations, the video signal can be overlayed on a pixel basis.
This makes it possible to overlay a portion of the frame and mix the signal with
externally generated video signal. Both the video source and the choice of pixels to
overlay can be changed dynamically.
Jumpers W7 and W23 are used for enabling or disabling the Video Feature Connector:
•
Enable: Open W7 and short W23;
•
Disable: Short W7 and open W23 (This is the initial setting).
Note: When the video feature is enabled, certain restrictions apply to the Flat Panel
connector. Contact Technical Support for more information.
The connector’s pin-out is described below. See Diagram 13-1 for the location of J11.
