64.75.150.222 Fixed an error in the 1st pinout diagram (audio pins were reversed)
Line 1: Line 1:
-===== Japanese 21-pin RGB connector ===== 
-The Japanese RGB-21 connector, also known as EIAJ TTC-003 apparently, 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]].

-=== Simple version ===

-^ Pin ^ Description ^ Pin ^ Description ^ 
-|  1 |Right audio  |  2 | NC  | 
-|  3 |Left audio shield ​ |  4 |NC  | 
-|  5 |Left audio  |  6 |NC  | 
-|  7 |Sync shield ​ |  8 |NC  | 
-|  9 |Sync  |  10 |NC  | 
-|  11 |+5v  |  12 |NC  | 
-|  13 |Red shield ​ |  14 |NC  | 
-|  15 |Red  |  16 | 1V*  | 
-|  17 |Green shield ​ |  18 |Blue shield ​ | 
-|  19 |Green ​ |  20 |Blue  | 
-|  21 | Ground ​ | 
- 
-  * *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.  ​

-Special Notes: 
-  * Audio Input: 0.40 mVrms, > 47K ohms 
-  * Audio Output: 0.40 mVrms, > 10K ohms 
-  * 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
