tional RS232 interface for communication with printers and computers. When
the Indicator is connected directly to a printer or a PC, displayed data can be
recorded at any time by simply pressing the Print/
Units button.
Connecting the Indicator to a computer enables you to operate several func-
tions of the Indicator from the computer, as well as receive data such as
displayed weight, weighing mode, stability status, etc.
