3.6 KNX/EIB Interface (Optionally)
Purpose
This board is used to establish a connection between ambiento
and the installation bus EIB/KNX. The USB connector has a
galvanic separation from the EIB/KNX bus. The circuit is
compatible with KNX medium TP1 (EIB), the firmware supports
protocol EMI1.
For manual changing of the KNX adress you can
