National Instruments Supports USB in Latest Bus Interface Software

6/11/2003 - National Instruments announced that its NI-Device Version 1.4 and NI-VISA Version 3.0 bus interface software products now support USB.

Instrument developers can use NI-Device 1.4 bus interface software to create USB firmware in addition to GPIB and Ethernet firmware for their ANSI/IEEE Standard 488.2 devices. NI-Device handles most of the IEEE 488.2 protocol requirements for the instrument developer. The software abstracts the communication bus from the instrument-specific firmware so that instrument developers can create bus-independent firmware that adapts to new communication buses while preserving their firmware investment. With NI-Device 1.4, instrument developers can write firmware for any instrument that runs a Windows 2000/NT/XP/Me/98 operating system when the connectivity interface support is through an NI PCI-based GPIB interface, the NI PCI-8211 GPIB/Ethernet interface or the new NI PCI-8215 GPIB/USB interface. NI-Device 1.4 is also offered in a DDK source-code package for support on non-Windows operating systems.

Engineers can use NI-VISA 3.0 bus I/O software to communicate with instruments that support USB in addition to GPIB, Serial, VXI, PXI and Ethernet. NI-VISA bus I/O software is a comprehensive software package for configuring, programming and troubleshooting USB, GPIB, Serial, VXI, PXI and Ethernet systems. NI-VISA features a complete set of high-performance routines for industry-standard programming environments and intuitive debugging tools. NI-VISA 3.0 software works with NI LabVIEW, LabWindows/CVI, Measurement Studio and TestStand as well as NI GPIB, VXI and PXI hardware.
