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 DC24 /2A power supply interface for connecting POS
printers as well as two mini DIN jacks for connecting the keyboard and
cash drawer.
Connect only devices approved by Wincor Nixdorf to
your BEETLE /M. If you have any questions, contact the
WN branch office responsible for your area.
Loudspeaker
A loudspeaker is connected to the CPU. The volume of the
loudspeaker can be set using the rotary knob on the rear panel of the
modular POS system. The loudspeaker is located behind the left-hand
side of the rear panel.
Nonvolatile RAM (NV-RAM)
This memory chip can be used to store important data - such as sales
totals or diagnostic entries - by means of the appropriate software and
independently of the power supply. The data is retained for more than
five years.
The NV-RAM is standard only in systems with the operating system
MS-DOS.
