-==== The Pinout ====
+===== Japanese 21-pin RGB connector =====
-The Japanese RGB-21 connector is identical in appearance to the European [[scart_connector|SCART]] (or Péritel or Euroconnector).  The pinout is completely different however.  There's an RGB<- ->SCART adaptor pinout [[scart2rgb|here]].

+  * *connect to pin 11 via 3.3k Ohm resistor.  The resistor isn't usually necessary, and +5v on this pin will most often work.
+=== Full Version ===
+This version includes every pin, including a few you'll never really need to know.  All labels are display-relative, so input means into the display.
+Most of these pins can be safely ignored for most purposes.

+  * CVBS (Composite Video) in and out: 1 Vp-p, 75 ohms, sync: negative
+  * Ym Input: Switches RGB to half-brightness, for video overlay (L: < 0.4V, H: > 1V, 75 ohms)
+  * Ys Input: RGB in/out: (Ground for output, 1V+ for Input (preferred)((A lot of displays won't show RGB at all without Vcc on this line)))
+  * All RGB lines: 0.7 Vp-p, 75 ohms
