I have a few Fujinon 'CYGNUS' servo drives for the 1:1.7/10-130mm lenses -
I was wondering what sort of signal to feed the 12 pin connector ... I imagine this was fed via some sort of tripod hand control ?
Upon opening the unit I see there are little motors that are geared up to potentiometers exactly the hobby servos (as opposed to optical encoders) - which makes me think they use PWM signals as opposed to step/dir signals ...
Any ideas/links ?
I'm hoping to convert them for my own needs - cheers!
