Interfacing with the
Typical Full Quadrature Pulse Train with Negative Velocity
Note: If excessive or erratic counts are noticed, the main cause is usually improper termination of the pulse signals. It is recommended you look at the signals (while connected to the external counter) with an oscilloscope to determine if excessive ringing or rounding of the pulse train is present. A 100Ω resistor can be used between true and false signals for differential output.
