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

ETS Connection Manager
The KNX IP Interface 730 can only act as an interface to KNX
when the IP-configuration is valid.
The following configuration steps are required:
Select the button ‘Settings’ on the tab ‘Communication’ in the
main window of ETS4. All available connections are listed under
‘Discovered connections’. Select the desired connection.
The KNX IP Interface 730 supports up to 5 simultaneous tunnel-
ing connections. Each connection uses its own physical address.
The address of the first tunneling connection can be changed
within the ‘Local Interface Settings’.
Physical addresses of the additional tunneling connections can
be assigned directly on the device.
This is done by pressing the learn key on the device (3) longer
than one second. After that, the Learn-LED will start blinking,
which indicates that the assignment of the additional addresses
was successful.
The additional addresses are assigned as follows:
Tunneling connection 2 receives the next higher address than
tunneling connection 1, tunneling connection 3 the next higher
address than tunneling connection 2 etc..
For example:
Device address: 1.1.255 (address within ETS topology)
Connection 1: 1.1.250 (address within local settings)
Connection 2: 1.1.251 (assigned by learn key)
Connection 3: 1.1.252 (assigned by learn key)
Connection 4: 1.1.253 (assigned by learn key)
Connection 5: 1.1.254 (assigned by learn key)
All addresses have to be unique and valid within the sub line of
the interface. Note: be careful not to assign the same address as
the device address for a connection. The device address can be
changed within the topology view of the ETS software.
For new devices (i.e. in the factory settings state), only the addi-
tional individual address of the first connection is active with the
address 15.15.250. To support multiple concurrent connections
additional address assignment is required.
Installation and connection
The KNX IP Interface 730 is designed for installation in a rack
with a depth of 2 units. It contains the following display and
control elements:
7
5
6
1 2
3
4
1:
Connector for external power supply (12 V to 24 V AC/DC)
2:
Connector for KNX with a bus terminal
3:
Learn key
4:
Learn LED (red)
5:
LED (green):
- Lights up to indicate bus voltage on KNX
- Flashes to indicate telegram traffic
6:
LED (green):
- Lights up to indicate an Ethernet connection
- Flashes to indicate telegram traffic
7:
RJ 45 socket for connecting an Ethernet patch cable
An external power supply only needs to be connected if the
switch in use does not support Power-over-Ethernet.
Factory reset
Factory default configuration:
Physical device address: 15.15.255
Number of configured tunneling connections: 1
Physical address of tunneling connection 1: 15.15.250
IP address allocation: DHCP
It is possible to reset the device to its factory settings.
Resetting to the factory state:
Disconnect the power supply to
the device (external power supply, PoE )
Press and hold down the learn key (3).
Reconnect the power to the device.
Hold down the learn key (3) for at least 6 seconds.
A blinking of all LED’s (4, 5, 6) indicates the successful
restore of the factory configuration
