MDR2i OLED Network Connectivity Overview Options
Air Compressor models which feature
the MDR2i OLED Smart Switch may be
connected to mobile phones, tablets,
notebooks, or computers. The switch can
be used as an access point or can be
connected to a Wi-Fi network.
This allows many air compressor features
and parameters to be entered and
controlled comfortably. Furthermore,
remote monitoring is also possible.
