NI-VXI is the name of the National Instruments VXI bus control library.
You can create applications using NI-VXI to control both VXI and VME
devices. NI-VXI gives you complete VXI/VME functionality, including
an API for performing basic VXI/VME data transfers and handling
VXI/VME interrupts as well as VXI-specific functionality, such as doing
message-based communication and handling VXIbus triggers.
NI-VISA is the National Instruments implementation of the VISA
specification. VISA is a uniform API for communicating with and
controlling GPIB, VXI, and VME and Serial instruments. This API aids in
the creation of more portable applications and instrument drivers.
