Geneve Video to EURO-AV (Scart)

Backgroud:

Last weekend I used a little to much force when I removed the plug of my Geneve Composite Video connector when testing my eprom programmer and thus swapping the eprom's in and out of the boardm. The result was a blank screen when I inserted the connector again. At first I thought it was caused by the new eprom on the Geneve, but when swapping the first Geneve for a second, I quickly ruled this out. So I started to look at the connector. To make things even worse, when I applied to much force to remove the shielding a bit, to see if a wire was loose, I ended up with a connector in one hand and the cable in the other. One thing was sre, it definitely didn't work anymore. So I had to completely rebuild the cable.
I searched for a schematic of the connection of the Geneve's Composite Video output to my Philips CM-8833 monitor's scart connector. I couldn't find one, so I decided to make one myself. The result is on this page.

Technical solution:

And here are the Geneve's Composite video output pin assigments and the standard EURO-AV connector aka scart connector's pin assignments.

EURO-AV Connector

DIN-8 Connector

Pin:	Description:	Pin:	Description:
1	Right audio out (connected to pin #3).	1	+12V when connected to a RF modulator else not connected.
2	Right audio in (connected to pin #6).	2	GND.
3	Left audio out (connected to pin #1).	3	Audio.
4	Audio GND.	4	Composite Video.
5	RGB Blue GND.	5	GND when used with a RF modulator else RGB Red (depends on jumper setting).
6	Left audio in (connected to pin #2).	6	RGB Green.
7	RGB Blue.	7	RGB Blue.
8	Not connected / Future use.	8	Composite SYNC (vertical + horizontal sync).
9	RGB Green GND.
10	Clock out.
11	RGB Green in.
12	Data.
13	RGB Red GND.
14	10 bit clock / Data ground.
15	RGB Red.
16	RGB Sync / Blanking signal.
17	Composite Video GND.
18	RGB Sync GND / Blanking signal GND.
19	Video out.
20	Video in.
21	Shielding / GND.

Connection:
The following connections needs to be made on the cable, connecting the right pins on both the DIN-8 connector and EURO-AV connector:

DIN-8 Connector --> EURO-AV Connector

#2 --> #17 (GND)

#3 --> #6 (Audio)

#4 --> #16+20 (Composite Video)

#5 --> #15 (RGB Red)

#6 --> #11 (RGB Green)

#7 --> #7 (RGB Blue)

And if everything went right and you turned on the Geneve and the monitor, you should see something readable on the monitor now... If not, you obviously did something wrong.
