KNX/EIB).

An acknowledge is only generated for received group telegrams (from
KNX/EIB) if they are routed to IP.
Acknowledge (ACK) of physically addressed telegrams:
Always:
An acknowledge is generated for every received physically addressed
telegram (from KNX/EIB).

telegrams (from KNX/EIB) if they are routed to IP.
Answer with NACK:
Every received physically addressed telegram (from KNX/EIB) is responded to
with NACK (not acknowledge). This means that communication with physi-
cally addressed telegrams on the corres-ponding KNX/EIB line is not possible.
Group communication (group telegrams) is not affected. This setting can be
used to block attempts at manipulation.
