Without knowing any details about the scale and how it communicates, you're going to be doing LOTS of trial-and-error testing to figure out how the thing works and what you're going to have to do to get the information you need. There's no standard to follow here. It could be as simple and opening the Serial port the scale is attached to (with the correct communication parameters of course!) and waiting for the scale to send you a weight. Beyond that, try it and see what happens. RageInTheMachine9532 "...a pungent, ghastly, stinky piece of cheese!" -- The Roaming Gnome

You can use the System.IO.Ports namespace in your project. The SerialPort class is very simple to use. I guess your weighting machine has a special way to send data on the port. If you don't know, I suggest that you use an RS-232 analyzer to see what's being sent by the weighting machine. fred. There is no spoon.
