22. TRANSMISSION POTOCOL
22.1. Some basic information
• The communication protocol has been designed for exchanging
information between RADWAG scales and external devices via
RS-232C.
• The communication protocol has been designed in the form
of request response messages.
• Scales always respond after receiving a command or automatically
after completing a command.
• Using the set of commands you can fetch some information from
scales or influence the operation of the device. E.g. It is possible to:
-
Identify the scale
Collect weighing results
Keyboard control
Display control
Changes of variables
Other
External software have to assure not sending the next command without
receiving the answer for the previous one.
22.2. Transmission parameters
• Scales are equipped in RS 232 (bidirectional) and RS485
(one direction from the scale to an external device).
