GPIB-VXI/C Addressing

[danzimmer]

Hi,

The manual for the GPIB-VXI/C board describes a procedure for configuring the board to use multiple primary addresses.  In this mode, the GPIB-VXI assigns primary GPIB addresses to the message based servants in the VXI chassis.  Does anyone know of an issue when using VISA to communicate with the VXI boards through a GPIB-VXI/C that is configured to use multiple primary addresses?

Thank you,

Hey dan,

When you use NI-VISA to communicate with your VXI boards through GPIB-VXI/C, you reference the board by its logical address, and not the primary/secondary address like you would with NI-488.2 (as referenced in KnowledgeBase 3YG82O5N : Converting a GPIB-VXI/C Program Using NI-488 Function Calls to NI-VISA). So the issue of multiple primary addresses shouldn't be any concern, since you're bypassing the GPIB's addressing altogether and letting the NI-VISA functions handle it.

Thanks very much, Justin.  Have a nice weekend!
