9 Interfaces

(except models EWJ-SM)
Via the interfaces weighing data may be exchanged with connected peripheral
devices.
RS 232 interface
For menu settings, see chapter 8.2:
„F3 COM"  „S 232"
Suitable peripheral devices:
• Printer

We recommend the USB interface set KERN DBS A02 (scope of supply: USB
cable, driver CD, software balance connection.)
For further information please go to KERN-Homepage (www.kern-sohn.com).
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.
