Data Interfaces
Data Input Format
You can connect a computer to your scale to send commands controlling weighing
instrument functions and applications via the interface port.
All commands use the same data input format. They start with the ESC character
(ASCII 27) and end with a carriage return (CR; ASCII 13) and a line feed (LF; ASCII
10). The total length of a command is anywhere from 4 characters (1 command
character between the start and end described above) to max. 7 characters
(4 command characters). This number can also be higher when sending texts.
The commands listed in the following table must each be supplemented with ESC ...
CR LF.
Example: The command character for output is “P” (“output to Port”). To trigger this
command, send the string: “ESC P CR LF”.
