Issue Details

I have a PXIe-8301 and I can see it in MAX, but I am not able to connect to it and do not have options available for Test Panels or Self Test. The link LED on the controller is solid amber. Why can't I communicate with my controller? 

Solution

This issue can be caused if you are using a non-Thunderbolt port with the Thunderbolt connection. To fix this, you need to connect your PXIe-8301 to a native Thunderbolt port. Most Thunderbolt ports are identified by a thunderbolt symbol next to the port, as shown in the image below. The most accurate way to tell if a port on your machine is a Thunderbolt connection is to reference its user manual or specification sheet.

Additional Information

Thunderbolt cables will fit into USB Type C, but Thunderbolt ports have other capabilities built on top of the USB Type-C form factor that are not in the USB Type-C specification, such as higher throughput and bidirectional PCIe and DisplayPort lines. Because of this, while you can see your controller, you are unable to connect with it since it does not have the proper data transfer mechanisms.

At the time of the publishing of this article, National Instruments does not sell nor recommend any PCIe cards with Thunderbolt ports since we have not tested them with our products and cannot guarantee their compatibility.
