FAQ

Product-specific questions

Product-specific answers based on available technical information.

Which software configures the VXI-USB?

NI-VXI uses Measurement & Automation Explorer (MAX) for configuration and provides the hardware interface for NI-VISA applications.

Does NI-VXI 16.0 support the VXI-USB on Windows 10?

Yes. The NI-VXI 16.0 readme lists VXI-USB hardware support and Windows 10 support in both 32-bit and 64-bit editions.

What should I check if large word-serial transfers time out?

The VXI-USB VISA timeout measures total elapsed transfer time, even while progress continues. NI notes that large word-serial transfers may require increasing VI_ATTR_TMO_VALUE.
