Doepfer

Technically speaking you can reverse the plug orientation ONLY if you  
do on both ends and ONLY if you make sure on the 10-pin plugs that  
the socket (the cable end) us lined up to the -12V pins and doesn't  
over hang that end of the header at all. The cables are just cables -  
no electronics involved. The cables use 2 wires for each voltage/gnd  
connection. the 2 columns of the headers are the same for each row  
(-12v, GND, +12v, +5v etc.) so should work even if only one column is  
plugged in though that cuts down the current handling ability of the  
cable. As you may notice the page referenced below does not mention  
the red stripe at all but it does stress "Pay attention that applying  
other than the described voltages or changing the polarity will  
result in the module’s instant destruction !" This will for sure  
happen if the cable ends are nor oriented the same at both ends.  
Doepfer has made this easy be printing the voltages next to the pins  
on all the modules I remember. In practice you should make sure all  
modules in your system have the same cable orientation and it it  
would be a good idea to match the orientation of factory delivered  
modules that have the cable attached already - just so you don't mess  
up when you re-arrange them in the future (and you WILL re-arrange  
them in the future!). A good arrangement would be to have the red  
stripe always at the -12v pins that way the cable will be easy to use  
on both 10 and 16 pin headers.
