17 RS 232C interface

The balance is typically equipped with a RS 232C interface. The weighing data can
be output depending on the setting in the menu either automatically or by pressing
or (in CFS 50K-3) via the interface.
This data exchange is asynchronous using ASCII - Code.
The following conditions must be met to provide successful communication
between the weighing balance and the printer.
• Use a suitable cable to connect the weighing balance to the interface of the
printer. Faultless operation requires an adequate KERN interface cable.
• Communication parameters (baud rate, bits and parity) of balance and
printer must match. Detailed description of the interface parameters see
chap. 12.2, Menu block "
