Use the I/O controls on the I/O and Classic I/O palettes to specify the instrument or device resource with which you want to communicate.

VISA Functions and Properties

Use the VIs and functions on the VISA palette to build VIs that control instruments. Use VISA properties to extend the functionality of VISA VIs programmatically. Before you begin using VISA, make sure you choose the appropriate method of instrument control.

For most simple instrument applications, you need only two VISA functions, VISA Write and VISA Read. Refer to the Simple Serial VI in the labview\examples\Instrument IO\Serial directory for an example of how to use VISA functions.

Use the VIs in the VISA Advanced VIs and functions palette to build advanced VISA VIs. Refer to the folders in the labview\examples\Instrument IO\VISA directory for examples of using advanced VISA VIs.

Refer to the labview\examples\Instrument IO\GPIB\GPIB.lvproj for examples of using VISA VIs with GPIB devices.
