Video input and TV output connectors

Matrox Orion’s video input and TV output connectors are BNC

connectors. It is important that when connecting a video source

to the video input connector, you do not connect an additional

video source to the

VID_IN1 pin on the expanded video I/O

connector. In addition, both the TV output and expanded video

I/O connector can receive the

You can use a standard video cable (available from your local

electronics store) to interface with these connectors.
