Data Output Rs 232; Pin Allocation Of Balance Output Bushing; Technical Data - KERN MWA 300-K1M Operating Manual

14 Data output RS 232

You can print weighing data automatically via the RS 232 interface or manually by
pressing via the interface according to the setting in the menu.
This data exchange is asynchronous using ASCII - Code.
The following conditions must be met to provide successful communication between
the weighing balance and the printer.
• Use a suitable cable to connect the weighing balance to the interface of the
printer. Faultless operation requires an adequate KERN interface cable.
• Communication parameters (baud rate, bits and parity) of balance and printer
must match. For detailed description of interface parameters see chap. 13.2)
