Ah ok, its using ascii protocol, so I guess as long as my monitor can translate that, I am good right?
Yes, that is correct, sort of.
Now you have to understand the formating of the ascii message, we call this a message protocol.
If you do not have any published information about the protocol, you can try to work out what it is.
Start with a known condition, eg no weight on the scale.
See if the same message is being sent.
Now add say 100g and see what the message changes to.
Keep doing this until you figure out what the format is.
