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