28. COMMUNICATION PROTOCOL
28.1. General information
A. A character protocol scale-terminal has been designed for
communication between RADWAG scales and external devices
via RS-232 interface.
B. It consists of commands sent from an external device to the scale
and a responses from a scale.
C. Responses are sent every time after receiving a command
(reaction for any command).
D. Using commands allows users to receive some information about
the state of scale and/or influence the operation e.g.: Requesting
weighing results, display control.
