11 RS232C-interface

11.1 General hints

For the connection of a peripheral device (printer, computer) the balance is as per
series equipped with a RS232C-interface.
The following conditions must be met to provide successful communication between
the weighing balance and the peripheral devices.
• Connect balance using a suitable cable with the interface of the peripheral
device. Faultless operation requires an adequate KERN interface cable.
• Communication parameters (baud rate, bits and parity) of balance and
peripheral device must match.
