Start with the weighing machine manufacturers site: that will tell you the format of teh data, and how to access / process it - which you need before you can even think about writing any software ...

Seriously, you need to know - so go back there, and ask their tech support: you need to know exactly what it sends and how that translates into numbers your code can use.

Without that, nobody can help you - you may as well guess!

You need to know that in the matter of serial communication, every brand have its own way to do it, and sometimes details vary with each model.
First, you need to get technical data about your scale, the manufacturer is best place to go, tech support.

Once I did an application for large company on 7 sites, I did 6 different routines to communicate with those scales.
Beyond the basic settings of serial comm, everything was specific on each routines.
