LabVIEW - Specify network card from multiple

33 Views Asked by At

Short story: Is it possible to specify the network card I want the LabView application to connect to the server?

Long story: I have a LabVIEW application running on customer test machine in a remote location. The application is responsible for two things: 1) test component, 2) connect with customer server to provide some information about the sample (i.e.: status of the sample after test). Testing of the component works without issue, the problem is customer network. Apparently, there is no possibility for remote connection from customer site using customer network. During the delivery we found a workaround by plugging a USB WiFi card and connecting with it to a hotspot from smartphone. Such solution however has a problem, the application tries to connect to the customer server through the USB WiFi card, not the customer network. Is it possible to solve this issue somehow? Is it possible to choose by which network card, the application has to connect to the server?

I tried to use the VISA write/read vi's, but without any luck.

Finally turned out to be network configuration issue, as Homer512 suggested.
