SNES:Video Output Notes

RGB Signals

All original NTSC SNES' output TTL sync from pin 3 on the multi-out connector. SNES Jr's can get TTL sync by [snesCSYNC.html connecting pin 18 on the S-RGB chip] to pin 3 on the multi-out. All RGB SCART cables that use CSYNC should have a 330-450 ohm resistor on the CSYNC line. Simply adding one to the SCART head is fine.

PAL SNES' have 12v on pin 3 of the multi-out. If you connect a CSYNC cable to a PAL SNES, you can damage your equipment! Instead, you can use a cable that gets sync from luma (pin 7) or composite video (pin 9) on the multi-out connector (luma recommended).
