I guess it's time to bite the bullet and figure out exactly how the data structures are configured. Does anyone know if there is documentation on this besides looking at the DS labview code?

You can only use the Printf -OR- the Add* + Finalize functions... not both on the same packer at the same time (without calling Finalize and waiting for a new DS packet). To use the Printf, simply stop calling the other functions on that packer. Then on the Dashboard side, instead of calling "unpack from string" on the received string, and instead use the string as is and write it to a file or an indicator or whatever.
