Step and Direction Outputs
The NI 9512 module supports both industry standards for stepper
command signals—step and direction, or clockwise (CW) and
counterclockwise (CCW) pulse outputs. The step and direction
output circuits are software configurable for either single-ended or
differential output type.
When connecting to drives with differential receiver inputs,
configure the output type in software to differential and connect as
shown in Figure 5.
