Instrument Drivers VIsUse Instrument Drivers VIs to configure, control, and retrieve data from GPIB, serial, modular, PXI, and other types of instruments. Use the NI Instrument Driver Finder to search for and install instrument drivers. If an instrument driver is not available, you can use the Create New Instrument Driver Project wizard to create a new instrument driver. If you do not create an instrument driver, you can use the Instrument I/O Assistant to communicate with message-based instruments.
