I have a PXIe-1090 rack. I can see the instruments in MAX, but not the chassis. I have run through all the database articles on this subject to no avail. I have tried this on two computers, a Dell Precision 7670 workstation laptop, and a Lenovo T14 Thinkpad laptop. The Thunderbolt Control Center on both shows the device as connected and correctly identifies it. Both the System and MXI lights on the front of the 1090 are lit green. I went through the entire set of actions in Cannot See PXIe Chassis When Using Thunderbolt, including reinstalling all software, all to no avail. Here is a screenshot of MAX showing the hardware and software in question. Any ideas where to go from here? I feel like I am missing something pretty basic.

Finally found it. One of my IT folks noticed that the devices were listed as locked in Device Manager with weird Device status. Searching for this error led to the following NI page. This led me to the correct BIOS item to turn off restrictions to DMA from the Thunderbolt port. The setting was hiding under the virtualization settings. The Dell BIOS does not have a Vtd entry, but it does have settings for DMA access under the virtualization settings. The original article I mentioned above did mention such a BIOS setting, but did not include enough information for me to find it.

Cannot Find PXIe-1090 in MAX

Solved!

I have not been able to get it to work since the BIOS update. I cannot revert because it was a security update and does not allow reversion.
