Bob - what data are you capturing / measuring? I was thinking of just writing a simple capture program from the unit and analyzing it in Excel.  When you say the status screen correspons to the data you've measured, what is it that you are comparing?

Hi

Based on what I ??ve seen on multiple boxes, I believe that the graph you have been looking at for TI is messed up due to a software bug. Checking things with a terminal program, the status screen corresponds pretty well to the data I ??ve measured.
