6.1) SCART / EURO-AV
(From Gerald Evans)

The pins have the following functions:

   1. Audio out B
   2. Audio in B
   3. Audio out A
   4. Audio ground
   5. Blue video ground
   6. Audio in A
   7. Blue video
   8. Function switching
   9. Green video ground
  10. Comms data line 2
  11. Green video
  12. Comms data line 1
  13. Red video ground
  14. Comms data ground
  15. Red video
  16. Blanking
  17. Video ground
  18. Blanking ground
  19. Composite video out OR synchronisation out
  20. Composite video in OR synchronisation in
  21. Common ground 

The pin numbering on the plug is as follows:

__________________________________________
\                                         |
 \  20  18  16  14  12  10  8   6   4   2 |  (case=21) 
  |   19  17  15  13  11   9   7   5   3  |
  |_______________________________________|

Note: This is as viewed from WIRING side.

Personally, I think SCART connectors are dreadful things. I mean, who really wants a 20 pin monster when only about 3 or 4 are ever used in any application. But it seems they are being forced upon us!

I think most VCRs just use the composite video (in+out) and the two sound channels (in+out sterio). By the way, quite a common fault with VCRs is that the scart socket gets disconnected from the PCB inside the machine. I have fixed 2 VCRs with this problem. It is not surprising really, because the leverage on the huge plug must be quite large if you pull it out carelessly etc.

The quicher SCART dies, the better, IMHO.
