Many users have devices that they need to use in multiple situations, such as a group of scientists sharing an instrument in the laboratory. The most common way this is done is for each user to physically carry the device next to his PC, connect the device, and then use it. NI-VISA for Windows and Linux now supports a more efficient way to do this. With remote NI-VISA on these supported platforms, you can leave the device connected to a single workstation and access it from multiple client workstations.
Remote NI-VISA is not a separate hardware interface type, but it is included in this help file for completeness.
