KNX IP Interface 730
Operating and installation manual
Application
The KNX IP Interface 730 can be used as an interface for ac-
cessing the KNX via IP, replacing an RS232 or USB interface.
The device supports 5 simultaneous KNXnet/IP tunneling con-
nections.
There are two ways to assign an IP-address to the KNX IP Inter-
face 730: get the IP-address from a DHCP-server or configure it
with the ETS (as ETS parameter).
It requires an external 12 V to 24 V power supply (AC or DC) or
can alternatively be powered via Power-over-Ethernet (IEEE
802.3af).
ETS database
The following parameters can be set on the ETS:
General:
Device name:
The KNX IP Interface can be assigned a name of your choice.
The device name should be descriptive (e.g. Line TF). It is used
to search for and recognize a device.
IP address assignment:
Automatic
(DHCP):
The IP address is automatically assigned on
the DHCP, i.e. additional settings are not re-
quired. To be able to use this function, there
must be a DHCP server in the LAN (many DSL
routers have an integrated DHCP server).
Manual:
In this case, the IP address, the subnet and
the gateway IP address must be entered man-
ually.
IP configuration:
IP address:
This is the IP address of the KNX IP Interface 730.
IP subnet:
Enter the subnet mask here. The device uses the values entered
in this mask to determine whether there is a communications
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 telegram.
IP gateway address:
Enter the IP address of the gateway here.
Note: If the KNX IP Interface will only used in the local LAN, the
entry of 0.0.0.0 can remain unchanged.
Example of assigning IP addresses:
A PC is to be used to access the KNX IP Interface 730.
IP address of the PC:
192.168.1.30
Subnet of the PC:
255.255.255.0
The KNX IP Interface 730 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
interface 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 IP interface:
192.168.1.31
Subnet of the IP interface:
255.255.255.0
