If it's counting gears as they rotate, it's an encoder. Encoders can be magnetic, optical, proximity, mechanical, or any other consistent means of detecting a fractional rotation or motion.
Thanks for the info. Would we have to use the talon SRx in cAN mode or in pwm mode if we hook it up that way. Also would we still have to set the distance per pulse.
