Can you run a longer wire from motofocus hand controller to focus motor? I was thinking of buying a FCUSB, but can I just run a 25ft extension wire with male to female ends? Can the 9v battery push the current through such a long run? If yes, what cable do I buy?

nFOCUS (uses 3 AA's kicked up to 12 V) has been run at cable lengths to 50ft. Radio Shack sells (used to sell) a mono headphone extension cord. 1/8" mono plug on one end and socket on the other.

Is this a JMI unit? If so, no problem making a longer extension, works just fine.

no, it's a rigel system unit, but the JMI unit should be able to operate at 25 ft no problem, using the 1/8" mono extension cable.
