13 RS-232C interface

A standard scale is equipped with a RS-232C interface used to connect a peripheral
device (e.g. a printer or a computer).
RS-232C

13.1 Technical specification

 8-bit ASCII code
 8 data bits, 1 stop bit, no transparency bit
 transmission speed selected in the range of 1,200–9,600 bauds
 Trouble-free operation of the interface is ensured only when the appropriate
interface cable by KERN is used (max. 2 m)
To ensure communication between the balance and the printer, the following
conditions must be met:
• Connect the scale with the printer interface using the appropriate cable.
Trouble-free operation is ensured only when the appropriate interface cable by
KERN is used.
• The scale and printer transmission speeds must be compatible, see
chapter 11.3.
