7.4 Interface RS 232C
Data output via interface RS 232C
General Information
The previous condition for the data transfer between balance and a peripherical device (e.g. printer, PC ...) is
that the appliances are set to the same interface parameters (e.g. baud rate, parity ...).
7.4.1 There are 4 kinds of data output via RS 232C
Data output using the PRINT key
The printing process can be triggered by pressing the PRINT key.
The settings AUTOPRINT and AUTOPRINT PC should be disabled for this process.
AUTOPRINT (data output according to weight application)
The setting AUTOPRINT is located on the PRINTER path where you can turn it on or off. When AUTOPRINT
is active, the current weighing value will be sent via the RS 232 date interface after unloading and subsequent
loading of the balance as soon as the balance is in resting position.
AUTOPRINT PC (continuous data output)
The setting AUTOPRINT PC is located on the PRINTER path and where you can turn it on or off. When
AUTOPRINT PC is active, the current weighing values will be sent continuously via the RS 232 data interface.
Data output and remote control commands
Remote control commands transferred as ASCII characters to the balance can be used to trigger the following
functions on the balance (always finish with CR, LF!):
t Taring
w The balance sends a weighing value (also unstable) via the serial interface.
s The balance sends a stable weighing value via the serial interface.
After receiving either character w or s, the balance will send without a printer pause between the characters.

7.4.3 Numerator
The numerator is situated under the menu item "Printer" where it can be activated or deactivated.
When data output takes places via the printer key, it will be increased by one digit per key stroke.
