Balance

D-SUB9P

9 RS 232C interface

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 (Baud rate, parity, see chap. 8) of display device

and printer must match.
