Are you talking about data or network connections? Others' suggestions
are all related to network connections.

It sounds like you just want to isolate the instrument's computer from the
big band network since it can not be properly managed.
Why not just add a second network card to the machine that you will be
using to fetch the data and connect the two with a cross-over cable. That
would handle the use case you described with mimimal complexity. You'd use
it as you would if it were on the main network but it would actually be on
it's own (small) private network. Your "second system" can then act like
a typical file server to the rest of the network.
