We're trying to use a VTI EX2500A LXI-VXI Slot 0 Bridge with a register based VXI card. VTI's solution involves the use of Agilent's VISA either by itself or in conjunction with NI-VISA. The controller/bridge needs to be treated as a VXI device and not a network device. When using Agilent VISA as a secondary implementation the device shows up as a miscellaneous device (NOT a network device). It appears the trick is to set up the to talk over a network as a VXI device (not a network device). Our application will not allow the installation of both Agilent and NI implementations of VISA.

I'm looking into the issue with R&D. I'll be sure to let you know as soon as we find something.

Sorry about the delay in getting back to you. I contacted the VISA Product Support Engineer about this and learned that it is not possible using only NI VISA. To be able to communicate with the VXI devices through the LXI-VXI controller, an LXI-VXI VISA passport is needed but NI does not have one. The manufacturer of your controller suggests installing an Agilent plug-in that will allow this functionality. You can get more information on this here. It is possible that NI will develop a VISA passport to communicate with LXI-VXI controllers but that will depend on the demand. I would suggest filing this as a product suggestion on our website (search "product suggestion" at ni.com) so that R&D can better prioritize their efforts.
