Appendix A
Using the NI-VISA Code Instrument
A-4
ni.com
If you have more than one GPIB-VXI controller in your system, or if you
change the primary address of a GPIB-VXI controller from its default
(1 for the National Instruments GPIB-VXI/C), or if you have a GPIB-VXI
controller from another vendor, then you need to configure NI-VISA to find
such a controller. Use the NI-VISA configuration utility—MAX on
Windows,
visaconf
on UNIX—and explicitly add a GPIB-VXI
controller. You will be prompted for the GPIB controller number to which
the GPIB-VXI is connected (usually 0), a unique GPIB-VXI controller
number, which you are free to assign, and the primary and secondary
addresses to which you have configured this GPIB-VXI controller.
GPIB-VXI Summary
In summary, using VISA and the NI-VISA CI to program VXI devices
controlled by a GPIB-VXI is the fastest, easiest, and highest performance
way to develop and deploy your GPIB-VXI application. Although porting
the code from NI-488 to VISA is not simple in the case of register-based
programming, it will be high-performance code that is compatible with
native VXI controllers.
