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.

Pin	Name	Description	Signal Level	Impedance
1	AOR	Audio Out Right	0.5 V rms	<1k ohm
2	AIR	Audio In Right	0.5 V rms	>10k ohm

4	AGND	Audio Ground
5	B GND	RGB Blue Ground
6	AIL	Audio In Left + Mono	0.5 V rms	>10k ohm
7	B	RGB Blue In	0.7 V	75 ohm
8	SWTCH	Audio/RGB switch / 16:9, slow switch (10-12v), to force tv to switch on a mode (depends of the tv(old), sometimes set tv to AUX)
9	G GND	RGB Green Ground
10	CLKOUT	Data 2: Clockpulse Out, used in the 80"s by old videotapes
11	G	RGB Green In	0.7 V	75 ohm
12	DATA	Data 1: Data Out (Unavailable ??)
13	R GND	RGB Red Ground
14	DATAGND	Data Ground, remote control, wired and used by old videotape recorders
15	R	RGB Red In / Chrominance	0.7 V (Chrom.: 0.3 V burst)	75 ohm
16	BLNK	Blanking Signal, fast switch (1-3v), to force tv to switch on a mode (depends of the tv(recent), sometimes set tv to AUX)	1-3 V=RGB, 0-0.4 V=Composite	75 ohm
17	VGND	Composite Video Ground
18	BLNKGND	Blanking Signal Ground - ground for slow or fast switch (ground for pin 8 or 16)
19	VOUT	Composite Video Out	1 V	75 ohm
20	VIN	Composite Video In / Luminance	1 V	75 ohm
21	SHIELD	Ground/Shield (Chassis)

EasyLink Connection (additional)

Television connector		Video recorder connector
10	I/O Control Bus	10	I/O Control Bus

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?
