I need some help. I don't know much about electronics and I want to
to connect a Super Nintendo Entertainment System to a Sony TV with a
SCART connector on the back. I live in New Zealand so it is a PAL TV,
but it also supports NTSC input (ie you can push a button and it will
switch to a NTSC mode). I would like the best picture possible so a
RGB connection would be best, and I believe the TV will be able to
handle the sync? Can anyone tell me for sure?
Failing that I guess the next best would be a Super VHS connection.
So can someone please email me telling me how I can connect between
these two connectors for RGB and Super VHS output. An article appeared
in the April Radio-Electronics magazine but they didn't discuss SCART
connectors.
I would also like to be able to input stereo sound into the TV, but
to do that you need a matrix invertor, whatever that is?
Supposedly Redmond cable have all the connectors and cable, but I
don't know whether they would sell any which have SCART connectors on
them. Can someone find out for me? Can someone give me their address,
phone number and fax number.
The pins on the connectors of the TV and the SNES are as follows :
TV Scart connector

Super Nintendo Entertainment System Connector
---------------------------------------------
Pin No
--------------------------------------------------------------------------
1 Red Video For linear RGB monitor use.
One volt peak-to-peak off of an emitter
follower source.
Requires a series 200 ufd coupling capacitor.
2 Green Video (same as pin 1)
3 /RGB Sync For linear RGB monitor use.
Active low combined vertical an horizontal
sync pulses.
0 - 5 volt high logic source is CMOS and
TTL compatible.
4 Blue Video (same as pin 1)
5 Ground Provided to ease teminating of shielded
video and audio cables.
6 Ground (same as pin 5)
7 Super VHS "Y" The luminance channel for Super VHS video.
One volt peak-to-peak into a 75 ohm load.
Internally capacitor coupled.
8 Super VHS "C" The chroma channel for Super VHS video.
One volt peak-to-peak into a 75 ohm load.
Internally capacitor coupled.
9 NTSC Video NTSC composite video. The sync tips are at
ground.
One volt peak-to-peak into a 75 ohm load.
Internally capacitor coupled.
10 +5 Volts DC A limited amount of +5 Volts supply power
may be drawn out of this pin for sync
inverters or doing a stereo dematrixing.
11 L+R Sound The monophonic and stereo matrixed sound
appears on this pin.
One volt peak is suitable for amplifiers
but not headphones.
12 L-R Sound The stereo matrixed difference signal appears
on this pin.
Add pins 11 and 12 for left stereo: subtract
them for right stereo output signals.
