Has anyone come up with a solution to this problem? It seems like I am having the same problem with DP40 temperature indicator. It works fine using an older version of Labview (4.x). But since we upgraded to 7.1, I have had the same problem as described in this thread. I can open up Labview 4, and communicate with the instrument, but when I open up labview 7 on the same computer, I get a parity error or a timeout error. Any Ideas? Thanks Dave
