LK-IP/KNXs REG

IP address
Here the IP address of the LK-IP/KNXs REG can be entered. This is used to address the device via
the IP network (LAN). The IP addressing should be coordinated with the administrator of the
network.
Subnet mask
Enter the subnet mask here. The device uses the values entered in this mask to determine whether
there is a communication partner in the local network. If there is no partner in the local network, the
device will not send the telegrams directly to the partner but to the gateway that routes the tele
-
gram.
Default gateway
Enter the IP address of the gateway here, e.g. the DSL router of the installation.
Routing Multicast Address
This address is used for routing telegrams on IP. The multicast IP address 224.0.23.12 was reserved
at the IANA (Internet Assigned Numbers Authority) for this purpose (KNXnet/IP). If a different
multicast IP address is required, it must be within the range of 239.0.0.0 to 239.255.255.255.
Example for the assignment of IP addresses:
A PC is used to access the LK-IP/KNXs REG.
IP address of the PC:
192.168.1.30
Subnet of the PC:
255.255.255.0
The LK-IP/KNXs REG is located in the same local LAN, i.e. it uses the same subnet. The subnet
constrains the IP addresses that can be assigned. In this example, the IP address of the IP router
must be 192.168.1.xx, where xx can be a number from 1 to 254 (with the exception of 30, which is
already in use). It must be ensured that no numbers are assigned twice.
IP address of the KNX IP router:
192.168.1.31
Subnet of the KNX IP router:
255.255.255.0
