LED Usage
The Wireless M-Bus Range Extender features a dual color led which is used to signal multiple states and activities. Most of time the Range
Extender will stay in a power saving state in which the led is switched off to save current. Visualization of internal Range Extender firmware
state is done after power-up and can be triggered by means of an magnetic input signal via reed switch.
