I've been meaning to get it out and see what it looks like when removed from the panel. I suspect the outputs are a pair of quadrature signals for both the continuous dial, and the spring loaded center=0 back dial. That dial, in the case of this device was able to move the tape at any speed from less than a frame per second to full fwd/rev speeds the capstan motor was capable of, and the last step released the pinch roller for full fast forward and rewind, but I believe that was done in the dvc-pro's os rather than in this device.
If and when I figure what sort of signals it can output, I may be back for hookup and config advice. > > > >------------------------------------------------------------------------ >- Take Surveys.
