And there are 2 channels putting out pulses but they are out of phase with each other. Using that difference you can determine the direction the axis is turning. Use an oscilloscope to test the outputs and observe the pulse train...

This is for a quadrature-type (optical) encoder. The original poster is describing the magnetic encoder that came in the kit of parts this year.
