Connecting external

connector
Matrox Orion's encoder can output NTSC/PAL and RGB video,
through the expanded video I/O connector, and composite video
in NTSC/PAL through the TV output connector. To connect
devices to the expanded video I/O connector, use the optional
DBHD44-TO-13BNC cable, connecting the wires as described
below:
Wires Signals
White (5) RED_C_OUT
Yellow (6) GREEN_Y_OUT
Purple (7) BLUE_COMP_OUT Encoded Video Output
To connect to the TV output connector, use a standard video
cable (available from your local electronics store). Note that
devices connected to the TV output connector are connected to
the BLUE_COMP_OUT line without a multiplexer. This means
that the signal can be received from both the TV output and
expanded video I/O connectors simultaneously; however,
connecting to both will result in poor video quality. The signal
path for these connectors is illustrated in the block diagram at
the beginning of Chapter 1.

Attaching a video input

You can attach video sources to Matrox Orion's expanded video
I/O connector using the optional DBHD44-TO-13BNC. This
cable has thirteen BNC connectors, and a DB-44 plug. The
DBHD44-TO-13BNC cable supports eight video input signals,
3 video output signals (described in the above table), and 2
trigger signals. The wires of this cable are color-coded and
numbered as follows:
