COMMUNICATION PROTOCOL
General information
A. A character based communication protocol scale-terminal is designed for
establishing communication between RADWAG scale and peripheral
devices via RS 232 interface.
B. It consists of commands sent from a peripheral device to the scale and
responses from the scale.
C. Responses are sent from the scale on each receipt of a command as
a reaction to a specific command.
D. Commands forming the communication protocol enable both, obtaining
data on scale status and influencing its operation, e.g.: acquiring
measurement results from the scale, zeroing, etc.
