Caution
Do not connect these outputs to anything other than a +5 V circuit. The output
buffers will fail if subjected to voltages in excess of +5.5 V.
Do not connect any unused output lines directly to COM, +5 V OUT, or V

Step and Direction Output Circuit
You can configure the active state of both outputs in software as low or
high. The active state of the direction output corresponds to a forward
direction. The step and direction output circuits can be configured in
software for either single-ended or differential output type. Refer to the
NI SoftMotion LabVIEW Help for more information about stepper motor
signal settings.
