SCART pins and their functions

Since I use this blog as a repository (via the search box on the right - go on, give it a go!) and a colleague asked me about SCART pins today I thought I'd better squirrel the info away.

Note: Pin 8 provides function switching. Applying 9.5-12V to the pin will cause a compatible TV or VCR to switch to the AV (SCART) input. It may also switch on the equipment from standby. Applying 0V or leaving unconnected will switch back to TV. Some TV's also use this pin to select the aspect ratio. Applying 5-8V to pin 8 will switch to 16:9 mode. This may be used by DVD players to set TV to correct ratio. Connect ground to pin 14 or pin 18.
