I want to connect a scart connector to the back of my case, but i cant find any tutorials or pinouts how to connect it...

The only place that perhaps could have it is SPILLAGE tutorial, but this site dont seems to work anymore! sad.gif

Help pleease!

Hope this helps, I just made a diagram to hopefully clear up what goes where and what does what.
Some of the information included was not originally found myself but I have verified it by taking apart my own Microsoft SCART AV cable and checking all the wiring.

I know they have been posted already but here are my tables for the SCART and AVIP pinouts:

My 1st diagram is wired for RGB and Composite video output.
RGB is the best format to use if your TV supports it on the SCART socket you have your XBOX plugged into. Usually TVs only support RGB on a limited number of its SCART connectors, so check when you cycle through your AV inputs to see which one has RGB. If no RGB is available then you will still get a picture using Composite Video (All signals down one cable).

My 2nd diagram uses two switches, one to change the XBOX video mode, the other to select RGB & Composite Video output or S-Video output.
Because of the later introduction of S-Video to the SCART plug standard and there being no pins reserved for it, S-Video uses the Composite and Red video pins for its connection. Therefore you cannot use S-Video at the same time as RGB or Composite video.
Even though the XBOX outputs Composite Video at the same time as RGB Video in RGB SCART mode and Composite Video and S-Video in Advanced AV mode (because it can be sent on separate connectors), you need to switch the SCART connector from the standard SCART mode (RGB & Composite) to S-Video SCART mode.

Sorry for going into so much depth about all that but I figured some people out there might be interested and it might clear a few things up.
Anyway, the top switch changes the XBOX video Mode. The switch at the side changes the SCART Mode.

My 3rd diagram is the same as the one above except instead of using two switches to selcet the mode and the S-Video wiring, I've used a single 3 pole-2 way switch to combine the two functions into one switch.

Was just thinking about my previous post...  I'm not entirely sure if the XBOX outputs Composite video when in RGB SCART mode.... if not then my 3rd design is incorrect and I will have to modify it.

I also realised that if it does output Composite video at the same time, then switching to it will also require disconnecting the Blanking pin, otherwise the TV will still think its getting RGB.

For the time being if you need Composite video out use the 2nd design and switch it to Advanced AV mode on the top switch and select RGB / Composite SCART mode on the side switch.

I will test the Composite out in RGB SCART mode as soon as I have chance and post my findings.


There is also one other point I need to make. If you wish to use the XBOX AVIP port for other AV cables, you will need to use switches in place of the jumper wires to set the XBOX video mode (pin 9-10, pin 11-12, pin 13-14).

I will add another design with this implemented as soon as I have time.  cool.gif

Just a quick update, I've just tested the RGB SCART to see if there is Composite Video on the Composite Sync wire... and there is  smile.gif

This means that my designs are almost correct except for the blanking signal that needs to be switched off if the  XBOX is set to RGB SCART mode and Composite Video output is selected, otherwise the connected TV will still enable RGB input and not Composite.

On second thought.... it shouldn't really matter if the Blanking signal is present because if the SCART socket on the TV is RGB compatible it will sense the Blanking signal and use RGB (best quality), if it is not RGB compatible then it shouldn't sense the Blanking voltage and just use the Composite Video signal (average quality).

If what I think is true then all of my designs are fine. You would probably only need to use S-Video (medium quality) if the SCART socket on your TV doesn't support RGB but does support S-Video.

The rating of quality for the three video formats is based on the quality of the signal (bandwidth) but can vary depending on the circuitry within you TV or any other device the signal connects though. You may find you get better results using S-Video than RGB, but both should be better than Composite.

For the BEST quality, if you have the connection on your TV, use Hi Definition Component Video (YPrPb).
Another option is to use a VGA, but for that option you need a Component to VGA transcoder or a modified BIOS (ModChip or SoftMod) with a custom VGA cable (for the latter option check out Frosty the Snowman's work HERE
