5.10 Addressing the IP router

5.10.1 KNX network address

IP routers require an auxiliary voltage of DC 24 V or AC 24 V (SELV). This auxiliary
voltage must be derived from a supply without a choke.
We recommend the Siemens power supply unit which has separate outputs for the
DC 29 V bus power and the DC 24 V auxiliary voltage (see section 2.2.3).
For operation of the IP routers with an AC 24 V auxiliary voltage (instead of
DC 24 V), the AC 24 V operating voltage, also used to operate the Synco devices,
is recommended.
The KNX network address of an IP router determines whether the router is
operated as an area coupler or a line coupler.
• IP router as an area coupler IP Ac
• IP router as a line coupler
For an IP router used as an area or line coupler, the KNX network address is set in
"Programming mode" via ACS Service.
The procedure is the same in principle as for an area/line coupler (see the notes on
addressing the line couplers, section 5.9.1).
The IP address and other data point values for Ethernet communication can be set
via ACS Service (see section 8.3).
