Scart Connector

Keene Electronics Sterling Gold scart plug

The wonderful scart connector is also known as a peritel connector. The table below gives the most common connections for the scart plug but by no means all. The Japanese for example use a completely different pin out for their (internal market) games consoles.

There are also a wide variety of scart to phono (or S video) adaptors available. These useful devices can be a bit of a pitfall as there are about 10 different types all using different connections. Buy one connected to audio and video in and try as you might you wont get a picture out of it.

When buying a scart cable you should always go for a fully screened cable. This is because if connecting say a VCR to a TV at the same time as the VCR is sending your video to the TV, the TV is also sending whatever station internal tuner is set to, to the VCR. In unscreened leads (and in some cases even with screened leads) this picture can get imprinted (video cross-talk) onto the video you are trying to watch as a ghost image. One solution would be to carefully cut the out put leads at the TV scart end. (pins 1, 3, and 19)

Another small problem which sort of involves scart connectors and RGB is as follows.

When using a STB as a source you can usually only get RGB from the scart labeled "TV". As there is no "S video" out put from most STB's a RGB2S video convertor is the best way of recording the signal. Assuming of course that you have an "S" VCR . All fine so far, but if you now decide to use the STB's timer recording facility you will get nothing because the STB will only wake up the VCR scart when using timer recording and the TV scart remains dead.

Anyway the connections for a scart are:

Pin Used for Specification and notes

2 Audio in right Line level audio
3 Audio out left Line level audio
4 Ground  
5 Blue Ground   
6 Audio in left Line level audio
7 Blue / Cb 75R video 0.7v peak  / Cb in component video (usually!)
8 Auto switching control 12 volts AV mode  / 8 volts AV mode widescreen ( if supported) 0 volts RF
9 Green Ground  
10 Comms data 2 / V sync SyncBlaster Vertical TTL sync / Data comms 2 on some VCRs and STBs
11 Green / Y
