PC protocol
A PC can be connected to the serial port of the scale. The PC
can then act as a remote terminal to control the scale, and
display scale / weight information.
To set up the scale for PC protocol you must first configure
the following:
•
Serial port configuration- Branch 36 on page 33
•
Printer configuration - Branch 38 on page 34
PC protocol commands and codes
The scale’s RS-232 bidirectional communication works in a
server/client protocol. A computer server sends a command
code to the scale (client) which will return a response to the
server device or perform a scale function. Commands to the
scale are in uppercase, terminated with a carriage return.
Scale responses begin with the lowercase equivalent of the
command code.
