KNX communication always requires a bus power supply. There are two types:
• Decentral bus power supply DPSU = Decentral Power Supply Unit
• Central bus supply
See data sheet N3127 and documentation on basics P3127 for more information on bus power
supply.

Data point
IP address
Default val:
192.168.251.1
Setting val:
Network admin.
Commissioning instructions OZW775 V2.01
Parameterize OZW775
Explanation, example
With "Decentral bus power supply = On", the
central communication unit supplies 25 mA to
the KNX bus (short-circuit-proof).
The green KNX LED is lit when bus power is
supplied.
Setting value "Master" if DP "Time
synchronization = Mains frequency".
Setting value "Autonomous" if DP "Time
synchronization = Quartz".
Setting value "Yes" is important for DP "Time
synchronization = Slave on bus".
With "Remote setting clock slave Konnex =
Yes", you can change the clock time of the clock
time master on the KNX network using ACS (via
central communication unit).
Bus power supply from Synco devices on the KNX network.
PSU
= Power Supply Unit
Bus power supply from voltage supply units.
Explanation, example
When you integrate the central communication
unit as web server in an Ethernet TCP/IP
network, contact the network administrator for
the IP address.
IP address 192.168.251.1 (default) is valid when
you integrate the central communication unit as
web server in a private network (LAN) and if it
corresponds to the address structure. Range for
IP addresses for private networks: 192.168.0.0
to 192.168.255.255.
