Overview

Product overview

Key product information and technical features.

The PCI-STEP-4CX belongs to National Instruments' ValueMotion stepper-controller range. NI's motion selection guide distinguishes PCI and ISA ValueMotion stepper boards from the family's PXI/CompactPCI products; this catalog model is a PCI controller.

Software selection is an important integration consideration. NI identifies the PCI-STEP series with ValueMotion software, and its historical compatibility table lists legacy Windows environments rather than Windows XP or Vista. Confirm the existing application's driver and operating-system requirements before changing the host computer.

FAQ

Product-specific questions

Product-specific answers based on available technical information.

Which driver family does the PCI-STEP-4CX use?

It uses ValueMotion. NI identifies the PCI-STEP controller series separately from the later controllers supported by NI-Motion.

Is Windows XP officially supported for this controller family?

NI's historical compatibility table marks Windows XP as unsupported for PCI-STEP controllers using ValueMotion. Do not treat operation reported on an unsupported system as official compatibility.

Is the PCI-STEP-4CX a PXI controller?

No. This model is a PCI controller. NI's ValueMotion selection guide separately identifies PCI/ISA stepper boards and PXI/CompactPCI stepper boards.
