Scanners and scales (COM1 - COM4*)
Depending on how the system is configured, scanners and scales
without an independent power supply are connected to the COM2*,
COM3* or COM4* serial interface (standard setting COM3). Connect
scales with their own power supply to the COM1 interface. COM1 is
designed as a 9-pin D-sub plug, whereas COM2* - COM4* are 9-pin
D-sub jacks.
Make sure that the scanner connector is plugged securely into the
socket to prevent possible malfunctioning.
If scales which are not supplied by Wincor Nixdorf are
connected to the BEETLE /M, you must obtain an WN
licence for the driver software.
If COM2 is equipped with a connector, the interface does not carry a
current.
