Pinout for SWM motor unit for Nikon Nikkor 18-70 mm F/3.5-4.5 DX lens
5 months ago

Hello,

I am a research student at NC State working on a project involving ultrasonic motors. I have ordered this SWM motor unit for the 18-70mm lens and having some trouble figuring out how it works. There is a 4 pin ribbon cable connected to the motor ring. After calling Nikon, other camera repair places, and visiting a camera shop I am unable to get the "pin out" for this connector. My question is does anyone know what these 4 pins actually do (ie voltage, ground, control, frequency specs etc.) and possibly where I could get more information?

Thanks!
