On demand scale can be equipped in two serial interfaces. Each interface can be executed in RS232C or RS485
standard.
Main interface marked as RS...-I enables bi-directional data transmission and can be used to connect device:
computer, printer and label printer.
Additional interface marked as RS...-II enables one-way transmission and can send data to additional display (no
keyboard). Additional joint can realize continuous transmission of actual scale indication.
Using both interfaces needs requires special firmware (on demand).
