RS-232 Interface - switch
The CX-one Printer contains two separate RS-232 interfaces, one for controlling the
printer mechanism and the other for controlling the chip-reader.
To control both units (printer and chipreader) with one interface we integrated a special
‚interface – switch’ to the CX-one. With the command <ESC>6 (transparent-mode) the
RS232-HOST interface can be switched from the printer to the chip-reader unit.
