Pinouts of different RGB connectors

This documents has some RGB connector pinouts which might be useful to VGA to TV converter circuit experimenters who wish to connect their PC to some other video display devices than normal TV.

The information is collected to various sources which I believe to be correct. I have not been able to verify every pinout in this document so there is no guarantee that those are the correct ones. So use this information at your own risk.

TV SCART

Here is the SCART RGB input pinout for a reference:

Pin Signal                     Signal level

 5  Ground (blue)
 7  Blue input                 (0.7V, 75ohm)
 8  Function select/AV control (9.5-12V = AV mode, >10kohm)
 9  Ground (green)
11  Green input                (0.7V, 75ohm)
13  Ground (red)
15  Red input                  (0.7V, 75ohm)
16  RGB switching control      (1-3V = RGB mode on, 75ohm)
17  Ground (sync signal)
18  Ground (RGB switching)
20  Composite sync input       (as in 1Vpp video signal, 75ohm)
21  Common ground (shield)

The connector itself looks like this:

   ----------------------------21

Monitors

Commodore 1084

Commodore 1084 is an RGB monitor designed to be used with Commodore Amiga and has the following specs:

Line frequency: 15625 Hz
Raster frequency: 50 Hz (47 - 62.5 Hz)
Resolution: 640 x 200 pixels (on RGB input)
The vertical resolution can be doubled if interlacing is used.

Some more information on that monitor can be found at http://www.epanorama.net/counter.php?url=http://www.interlog.com/~gscott/t-1084.html. The RGB connector in the back of the monitor has the following pinout:

Monitor                      
Pin   Description       
4     Red Video            
1     Green Video          
5     Blue Video           
3     Ground               
2     Horizontal Sync      
6     Vertical Sync        

Philips CM8833-II

Philips CM8833-II has quite similar specs to the monitor above (used in the same type of applications). Philips CM8833-II has a RGB connector which can accept both analogue and digital RGB signal. The RGB connector uses the following pinout:

_____________
\ 5 4 3 2 1 /
 \_9_8_7_6_/

 -Pin-    -RGB TTL-     -RGB Analogue-
   1      Ground        Ground
   2      Ground        Ground
   3      Red           Red
   4      Green         Green
   5      Blue          Blue
   6      Intensity     Fast Blanking
   7      Not used      Composite Sync
   8      H. Sync       H. Sync
   9      V. Sync       V. Sync     

Some of the CM8833-II models have also a sepearate composite video input (RCA connector). I have also heard of special versions with only the digital TTL RGB input.

DIN 45326

DIN 45326 is a standardized TTL level RGB input connector which is quite common in some older European computer monitors (for example Commodore 1084). DIN 45326 connector cna be for example used to accept the signal from PC CGA card with suitable cable. DIN 45326 connector has the following pinout:

Pin  Function

 1   Status computer
 2   Red
 3   Green
 4   Blue
 5   Intensity
 6   Earth
 7   H.syncronization or composite syncronization
 8   V.syncronization

The connector model is 8-pin round DIN connector (7 pins at 270 degrees and one center pin) with the following pin numbering:
