I figured it out. I just realized that the probes in LabVIEW are just created from controls (duh) and
there must not be one for the DAQmx terminal so it picked a string probe instead.
I was able to create a new probe from the terminal probe explicitely and it works.
I am curious however. I tried to create a new probe based on an existing one and none of the
DAQmx controls are listed in the list of existing probes, but I can probe (e.g.) DAQmx task name.
So where are those probes defined?
Thanks for listening.
