Configure NI-VISA to operate with a National Instruments GPIB-VXI/C
By default, the National Instruments GPIB-VXI/C is configured for primary address 1, secondary address 0. NI-VISA automatically detects it at this location. To use the GPIB-VXI/C with a different GPIB address, you need to add this device to your system manually in MAX. You can do this by right-clicking on Devices and Interfaces in the configuration tree and selecting Create New.... In the wizard, follow the instructions for entering the GPIB address (primary and secondary), VXI logical address, GPIB controller number (which GPIB plug in board the GPIB-VXI/C is connected to), and the GPIB-VXI number. The GPIB-VXI board number should be unique in your system.
If you have multiple GPIB-VXI controllers in your system, you need to configure only the ones that are not at the default GPIB address of primary address 1, secondary address 0.
