If you have less pins than the cable the missing 6 pins would be at the top of the cable and the red stripe being connected to the pins at the bottom.

The convention is the red stripe is always -12v and that's at the bottom, with a few exceptions with other brands

Those missing pins have to do with the bus Doepfer designed but only sometimes uses allowing the system to send CV and gate through the bus giving you normalized patching.
There is info elsewhere about it otherwise my post would get too long.

Anyway, Analogue Solutions modules afaik don't use the bus for gate and CV and actually I have an old analogue solutions case with only 10 pin unkeyed Doepfer connectors in it's bus. Rather dangerous but I don't think they make anything like that any more afaik.

Do take care about the red stripe. It is there to help you but in some cases it's possible to get things turned the wrong way. I know once or twice I wound up taking out a cable and putting the bus end in the module and the original module end into the bus to make the red stripe wind up oriented correctly.

Many modules have -12 marked if you look closely so you can trust that. If not I agree that you should contact the manufacturer if in doubt
