That's a mighty nice piece of kit you've got yourself there!
Thought I would confirm Dustin's comment regarding the motor pin outs i.e. Preston, Heden, Scorpio, ARRI CLM (most any digital motor using the 7pin 1B(size) Lemo). The standard pinout on these motors is:
1 - Motor +
2 - Motor -
3 - Encoder A
4 - +5V (Encoder Power)
5 - Gnd (Encoder Ground)
6 - Encoder B
7 - Motor ID
*In some oddball instances Encoder A & B may be inverted, but having them inverted wont damage the motor, just prevent it from running or the motor will just kind of spaz out. The inversion may be on the motor (though I cant even recall which if any do this), more comonly it's occuring at the motor controller. This seems to be outdated practice though, probably was meant to push cable sales. Most manufacturers of motor drivers have standardized now, usually on 7 or 14pin Lemo connections with 1 to 1 wiring, as to avoid confusion on set or damage to some pricey motors. That being said though, always verify your own systems wiring. These are rules of thumb that apply 99% of the time. That remaining 1% seems to be in cahoots with that jagoff Moore with his laws, always trying to keep a man down ;)
