36.  COMMUNICATION PROTOCOL 
  General information 
A.  A character based communication protocol balance-terminal is designed for 
establishing communication between a RADWAG balance and a peripheral 
devices via RS 232 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 for a specific command.  
D. Commands forming the communication protocol enable obtaining data on 
balance's status and influencing its operation, e.g.: request measurement 
results from the balance, zero indication, etc.
