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 (or Péritel or Euroconnector). The pinout is completely different however. There's an RGB← →SCART adaptor pinout here.
Simple version
| Pin | Description | Pin | Description |
|---|---|---|---|
| 1 | Left audio | 2 | NC |
| 3 | Audio shield | 4 | NC |
| 5 | Right 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.
| 1 | Audio left channel input | 2 | Audio left channel output |
| 3 | Audio ground | 4 | Audio ground |
| 5 | Audio right channel input | 6 | Audio right channel output |
| 7 | Video ground | 8 | Video ground |
| 9 | CVBS input | 10 | CVBS output |
| 11 | AV control input | 12 | Ym input |
| 13 | Red signal ground | 14 | Ground |
| 15 | Red signal I/O | 16 | Ys input |
| 17 | Green signal ground | 18 | Blue signal ground |
| 19 | Green signal I/O | 20 | Blue signal I/O |
| 21 | Plug shield |
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)1))
- All RGB lines: 0.7 Vp-p, 75 ohms

A lot of displays won't show RGB at all without Vcc on this line
