The balances have the ability to send data to the serial interface.
The weighing data can be sent over the interface either automatically or when
the user presses the [Print] key.
The user has control over what data is to be printed.
The following gives a description of the RS-232 interface.
HARDWARE
The RS-232 interface is a simple 3 wire connection. The input and output
connections are:

All lines are terminated with carriage return and line feed (<CR><LF>).
In continuous output mode, or if single-line output on demand is selected, the
serial output format will be a single line in the form "1234.567 g<CR><LF>".
The format of the single-line output will change depending on the mode in
which the balance is operating, as described below.
If output on demand is selected, the user may optionally configure the serial
