As we all know its horribly easy to insert the standard Losmandy DIN motor
cables incorrectly which wreaks havoc with the motor encoders and decoder
ICs.

I did this myself while repairing a G-1 recently, and only just caught the
problem before I turned it on (which would have destroyed the new motor
encoder and decoder IC I had just fitted).

So I tried to insert *my own* motor cables incorrectly.? It was almost
impossible to do so because they're made up with good quality metal DIN
connectors rather than the cheap moulded ones with stamped metal outer
section used on the stock cables.

I recommend the Deltron 610-0600 (or similar) for use with the G-1 and early
(large) G-2.? I think (but am not sure) that the Gemini-2 Mini is fitted
with Lumberg KGV-60 or KGR-60 sockets (or similar threaded joint DIN), in
which case I'd recommend the Lumberg SV60 plug (or WSV60 for a right-angle
version) for the controller end of the cable and the Deltron for the other
end.

So I'd strongly advise everyone to make up their own cables (or get a friend
to do so) using good quality metal din connectors and twisted pair cables
(stranded Cat-6 would work well) wired as follows:

Wire pin 1 to pin 1, 2 to 2 ... 5 to 5.?? Use one pair for pins 1 and 5
(motor power cables), one pair for pins 2 and 3 (Encoder Channel A and
Encoder Ground), and one pair for pins 4 and 6 (Encoder Channel B and
Encoder +5V), and.

If you use screened cable connect the screen to the plug body.
