Connecting to Matrox Helios eA/XA

The Matrox Helios eA/XA board has the following connectors:
• Two DVI analog video input connectors (on the bracket). Used to receive video
input signals and transmit/receive timing, synchronization, and communication
signals between the video source and the frame grabber. To each connector, you
can connect up to 4 video sources. Connector 0 provides source A for acquisition
paths 0 through 3, and Connector 1 provides source B for acquisition paths 0
through 3.
• Internal auxiliary I/O connector (50-pin). Used to transmit/receive the auxiliary,
camera control, timing, and synchronization signals in TTL format. The
connector is located on the edge of the board, making the signals accessible from
inside the computer enclosure.
• System reset connector
pressed or the Watchdog circuitry of Matrox Helios detects abnormal Host
inactivity.
To access the signals of the internal auxiliary I/O connector from outside of the
computer enclosure, you might have installed the corresponding adapter board.
It has the following connectors:
• External auxiliary I/O connector 0 (HB-44). Used to transmit/receive
synchronization and auxiliary signals. Note that all the signals can be in either
LVDS or TTL format.
• External auxiliary I/O connector 1 (DB-9). Used to receive opto-isolated trigger
input signals.
