Scale Interface to VB Application

Question

I have a few different scales that I'm building a VB app for. Is there a universal serial port language that is common among weight scales that I can use to import real-time weight into VB?

Answer 1

Yes, there's a standard protocol, formulated by the Scale Manufacturer Association. The spec download is here. Whether your actual scales follow that standard is an open question, check the small print in the datasheet or programming manual for them. It is rarely a real problem, these protocols are easy with simple command/response strings.
