9 Data output RS 232 C

The RS 232C interface allows a bi-directional data exchange from the balance to
external devices. This data exchange is asynchronous using ASCII - Code.
The following conditions must be met to provide successful communication between
the weighing system and the printer.

Use a suitable cable to connect the display unit to the interface of the printer.

Faultless operation requires an adequate KERN interface cable.

Communication parameters (Baudrate, parity) of display device and printer

must match.

9.1 Technical data

 8-bit ASCII Code
 1 start bit, 8 data bits, 1 stop bit, no parity bit
 Baud rate selectable at 1200, 2400, 4800, 9600 and 19200 Baud
 Miniature plug-in necessary (9 pole D-Sub)
 For operation with interface faultless operation is only ensured with the correct

KERN

– interface cable (max. 2m)
