Jims Mobile, Inc. (JMI) - PC Focus Control

PCFC controls a DC focuser motor from your PC through a USB port. 
Basically, it replaces a regular hand unit with control from a
computer using a mouse.  It gives greater control of speed and
duration of movement than a regular hand unit.  It can control EV
Focusers, NGF Focusers, RCF Focusers, MOTOFOCUS, MOTODEC and other
motors.  No batteries are required.  There is no encoder feedback or
positional display with PCFC.  If you desire focus control with
encoder feedback, please see Smart Focus.
