2.4 Signal connection

a) Connection of video signals

The connected equipment must comply to all relevant safety demands.

Important: The use of low-quality video cables can distort the video signal and influence diagnosis.

1.Check the impedance of the imaging board that produces the video signals you want to connect. It must be 75 Ohm (just like the input of the display). If not, the quality of the images on the display will be inferior.

2.Connect the video output of the computer’s imaging board to the video and sync inputs on the display’s rear panel. Use a proper video cable. The video cable is not supplied with the display, unless the display comes as part of a complete BARCO MeDis system, that also contains an imaging board.

The inputs accept the following signals:

Video with separate horizontal and vertical sync.

-The video cable has 3 wires.

-Connect the video signal to the connector Video {7}.

-Connect the horizontal sync signal to the connector HS/CS {8}.

-Connect the vertical sync signal to the connector VS {9}.

Video with external composite sync.

-The video cable has 2 wires.

-Connect the video signal to the connector Video {7}.

-Connect the composite sync signal to the connector HS/CS {8}.

Video with internal composite sync (sync on video).

-The video cable has 1 wire.

-Connect the video (with sync) signal to the connector Video {7}. Notes:

The video inputs cannot be connected in loop-through (daisy- chain).

The required video amplitude: 700 mV ± 3 dB.

The required sync. amplitude: 500 mV.
