That seems reasonable although to be clear, I did call the viOpenDefaultRM when making my own calls to the VISA API. So that suggests to me there is something beyond the content of that function. What I am also wondering is if NI considers this intended behavior, or if it unintended behavior that I could expect to see fixed in future versions of LabView / VISA?
It's most likely neither intended behavior nor anything NI will try to fix on its own. NI VISA is the defacto implementation for the VXIpnp VISA standard. This standard is published and you get access to a lot of documents and example codes to implement your own drivers if you are a VXIpnp consortium member. Not sure about the fee to be a member of this consortium but it is likely a considerable yearly amount.
Adlink seems to have access or having had access to this standard documents and implemented a VISA driver for their hardware. But it seems to not behave in a way that NI VISA will simply recognize it as a valid VISA passport and initialize it. The buck is obviously with Adlink here. they have to investigate what goes wrong and either fix their problem or report a bug to NI for not implementing the VXIpnp standard to the letter. Of course that assumes that they are still a member of the VXIpnp consortium. If they are not, I'm afraid all you can do is accept that that board never will work with NI VISA. NI is not going to spend even one engineering hour to fix a problem that affects another manufacturers and competitors hardware unless that manufacturer can proof to them with hard facts that their implementation is not according to the published standard.
Also I am not clear if you are an NI employee who knows this for a fact or an outsider like me? Or an AI 🙂 never know these days
Active NI employees usually have a blue color in the activity bar with the three rectangles to the right of the avatar icon. As to the post being from an AI, it absolutely does not look like a typical AI answer. They are normally neither as explicit and detailed as that response was and usually tend to be super well formulated but with little substance telling you with complete confidence half truths and fantasies as facts. The fact that it is a 1 hit wonder (a person having done exactly 1 post only) and seemingly having specifically signed up for this answer could be several things. It usually is a sign of a spammer, signing up, posting some seemingly useful information before going onto a spam run. But it could be also someone not wanting to post this under his normal account. Doesn't seem very likely, the information isn't exactly very sensitive, just a little bit outside of the normal advices.
Adlinks solution seems to be to suggest to instead install the Keysight IO Driver software suite.
My guess is that their VISA passport has certain problems that the Keysight VISA implementation is not so picky about.
