Programming KNX devices with ETS via the KNX Extension and the Miniserver as KNX Gateway is not possible. Therefore an external KNX/EIB gateway must be used. 


Install the unit in a suitable distribution box where it is protected from water, dirt and mechanical damage.

Connect the power supply (orange/white), the Loxone Link (blue/white) and the KNX bus (red/grey).

After switching on the power supply the device starts, the status LED flashes orange after a short time when connected to the Miniserver.
