The Matrox Helios eD/XD board has the following connectors:
• Digital video input connector 0 (100-pin). Used to receive video input (for
acquisition paths 0 and 1), timing, and synchronization signals and
transmit/receive communication signals between the video source and the frame
grabber.
• Internal digital video input connector (100-pin on the top edge). Used to receive
video input (for acquisition paths 2 and 3), timing, and synchronization signals
and transmit/receive communication signals between the video source and the
frame grabber. The connector is located on the edge of the board, making the
signals accessible from inside the computer enclosure.
• Internal auxiliary I/O connector (50-pin on the top edge). Used to transmit
timing and synchronization signals, and transmit/receive auxiliary signals. The
connector is located on the edge of the board, making the signals accessible from
inside the computer enclosure.
• System reset connector. Used to reset the motherboard if the reset button is
pressed or the Watchdog circuitry of Matrox Helios detects abnormal Host
inactivity.
To access the signals of the internal digital video input connector from outside of
the computer enclosure, you might have installed the digital video input adapter
board. It has the following connector:
• Digital video input connector 1 (100-pin). Used to receive video input (for
acquisition paths 2 and 3), timing, and synchronization signals and
transmit/receive communication signals between the video source and the frame
grabber.
