Editing SCART (section)

=== Direct connections ===

As audio and (composite) video use the same pins on "down" and "up" connectors (and require a crosslinked cable), it is also possible to connect two devices directly to each other without paying attention to the type of the socket.

However, this no longer works when S-Video signals are used. As straight links (RGB red and blue up) were re-purposed to carry chrominance information, the S-Video pinouts are different for "down" and "up" SCART connectors.<ref>{{Cite web|url=http://www.camp0s.com/pc_related/svideo/svideo.php|archive-url=https://web.archive.org/web/20111008112024/http://www.camp0s.com/pc_related/svideo/svideo.php|url-status=dead|title=S-Video to SCART signal conversion guide|archive-date=October 8, 2011}}</ref> Further, they are often not fully implemented.

Paying attention to the type of socket is essential when handling component RGB/{{YPbPr}}/S-video. Damage can be caused to devices incorrectly connected as follows:
*connecting SCART 1 ("up") from one device to SCART 1 ("up") of another device when both SCARTs are configured for RGB/{{YPbPr}}/S-video-up. Pins 7, 11 and 15 are outputs.
*connecting SCART 2 ("down") from one device to SCART 2 ("down") of another device when both SCARTs are configured for S-video-down. Pin 7 is an output.
*connecting SCART 1 ("up") from a device configured RGB/{{YPbPr}}, to SCART 2 ("down") of another device configured with S-video-down. Pin 7 is an output.

Damaging pins 7, 11 or 15 may result in yellow, purple or blue/green images, due to the missing blue, green or red components respectively. When using S-video, damaging pin 7 or 15 may result in black-white images due to the missing chroma component ("down" and "up" respectively). Similarly, damaging pins 7 and 15 (P<sub>B</sub> and P<sub>R</sub>) while leaving pin 11 (Y) undamaged may result in black-white images when using {{YPbPr}}. Damaging more than one of these pins may result in combined effects.
