Nem,
1. Serial RS232 connection: I assume that is established (voltage levels, baudrate, handshake, data/stop bits)
2. The VISA vis will handle the data (depending on your protocol bytes of any value in any order) as strings, but you can easily convert them to an array of bytes (or for sending from a byte array to a string).
3. The meaning of that bytes depends on your software (plain ASCII text or raw AD values (8bit or grouped 16/32bit with or without sign))
4. There are so many ways to read (RS232) data, to interpret and to display them, impossible to answer your question. LabVIEW makes it very easy to quickly realize your needs, however thousands of LV programmers solve these tasks daily in different ways.
I spend 8min to write a simple reader (including launch of LV
🙂 and even some comments :-0
maybe I could have been faster by using express vis and assistants... just not used to them
