LabVIEW
write to binary binary file
It's not only how you write it, but also how you read it later. How do you read the file?
Still your code makes very little sense and I recommend that you start with some tutorials or look at some shipping examples.
Whatever you have attached is a wild mix of datatypes, (strings, variants, U32 arrays, digital wavefoms, dynamic data, waveforms) and a hair rising wiring pattern. It is difficult to see any purpose in it all. Why do you convert the U32 array to a waveform via dynamic data before writing it to the file???. Can you eliminate the serial parts and add some typical data as diagram constants so we can see what you actually have and test the program?
Your different conversions are complex and some of your code just doesn't do anything (i.e. all of that stuff with the feedback loop in the read section. If you just want to write the binary data that you receive, you just have to do what is shown below.
p.s. Before posting again, you might want to clean up your diagram. It's hard to see what is going on with wires going every different direction.

Are you using the Read Binary File.vi example as shown below? Have you made any changes to it? It uses a constant of DBL data type for reading the file. You will want to make sure that constant is a U32 representation to match the data you are writing to that file. You will also want to make sure the Data Size constant is a 4 instead of 8 since it is a U32.
