Interfaces
The COM1 interface of the BEETLE /M is designed for connecting
standard peripherals that have a separate power supply. The COM2*,
COM3* and COM4* are provided for connecting special POS
peripherals that do not have a separate power supply, for example a
scanner or a display. The BEETLE /M is also equipped with a parallel
interface and a DC24V /2A power supply interface for connecting POS
printers as well as one mini DIN jack for connecting the keyboard. For
connecting cash drawers the BEETLE /M is equipped with two RJ12
jacks.
Connect only devices approved by Wincor Nixdorf to
your BEETLE /M. If you have any questions, contact the
Wincor Nixdorf branch office responsible for your area.
