Looks good, nice idea. With the Waveform, I notice you use an uppercase E rather than a lowercase one - all your other characters are lower case. Did you try putting a breakpoint on the wire leading to the Scan Value function to see if it's actually getting into that case?

I don't know if you realise, but there is a more efficient way of managing your cases. At the moment, you have 5 case structures, and the one that runs is determined by a check against the leading character in the data. You could use just one case structure and do this:

wire the output from the replace substring (the one that you currently have wired to an = block) to the case selector terminal - you don't need the = block. Then you can change the two entries that are created automatically so that one is just "default" (an error case because it should never get called) and the second to "t". Then add cases for your remaining letters (right click on the case structure edge.)
Where you currently have the output of replace substring entering each case into a Scan Value block: pull that scan value out of the case structure and instead wire the output of the Scan Value into the new case structure. This bit of code is the same in each of your current case structures so with just one case, it doesn't need running 5 times. Hope that makes sense?
In each case in the case structure wire the terminal from the Scan Value to the indicator it is used for. LabVIEW will run the case that matches the input letter, cases don't have to be just "true" or "false".
