Some encoders have an index pulse that happens once per revolution. It is useful for orienting the encoder when its initial position is unknown.
In Jaguar's case, whenever it sees an index pulse, the encoder count resets to zero. This is useful if you want to make an incremental encoder somewhat of an absolute encoder.
