SCART (Peritel; Euroconnector)

#Connectors#Audio-Video

This connector can be found at many video´s, TV´s and so on. The connector is also known as Pertitel connector or Euroconnector.

21 pin SCART FEMALE connector pin-out & layout

21 pin SCART FEMALE connector  at the video/TV

The Scart (Syndicat des Constructeurs d"Appareils Radiorecepteurs et Televiseurs) connector is used for combined audio and video connections.

A formal description is given in the CENELEC EN 50 049-1:1989 standard or in the IEC 933-1 standard.

Different pin-configurations exist. Which confirations are available depends on the video device used. Sometimes one can choose the configuration (like composite or S-video) by changing a software setting.

Two status signals define (partly) which video signals are active. A video device can use these status signals to automatically switch between internal or external audio/video signals.

EasyLink enables bi-directional communication between a television set and a video recorder. This way a video recorder can, for example, copy the channel settings of the television set. Who knows the details?
