What is the data that you are actually getting? From your earlier post, one could assume that you are getting hex information and you could use the typecast, unflatten from string, or String to Byte Array. As mentioned there, there have been numerous posts on the subject.
If you are really stuck, post your VI with some data. That means run the VI until you have data in the string indicator. From the Edit menu, select Make Current Values Default. Save it. Attach it.
