In fact, what you need to do is to make a serial communication program with VB first, and then ensure that this program can reliably send a specific code to the instrument, and then continuously collect the data code sent back by the instrument. Then the received code is recognized, saved and displayed. Quite simple.

Then, you can find the communication protocol in the manual of the instrument. The so-called protocol is: 1, what kind of fields the instrument receives before giving feedback, and what do the fields fed back from the instrument represent? If not, you might as well call the manufacturer, and they should actively cooperate with you.

Originally, it was a very simple matter. If you put a reward for wealth here, I'm afraid no one will answer, because it can already be a job.
