Reset to factory device settings
It is possible to reset the device to its factory settings:
•
Disconnect the KNX Bus connector
❶
from device
•
Press the KNX programming button
❸
and keep it
pressed down
•
Reconnect the KNX Bus connector
❶
of device
•
Keep the KNX programming button
❸
pressed for at
least another 6 seconds
•
A short flashing of all LEDs (
❷❹❺❻
) visualizes the
successful reset of the device to factory default settings.
Interface settings with ETS
Within the ETS KNX interfaces can be selected and set up via
the ETS menu "Bus Interfaces".
The ETS can access configured KNX IP Routers even without a
database entry. If the setup of the KNX IP Router does not com-
ply with the conditions of the KNX installation it must be config-
ured via an ETS project. See the ETS database section for more
information.
As factory default the assignment of the IP address is set to
“automatically via DHCP” and thus no further settings are neces-
sary. To use this feature a DHCP server on the LAN must exist
(e.g. many DSL routers have an integrated DHCP server).
After connecting the KNX IP Router to the LAN and the KNX
bus, it should automatically appear in the ETS within the menu
"Bus" under "Discovered interfaces".
By clicking on the discovered interface it is selected as the cur-
rent interface. On the right side of the ETS window all specific
information and options of the connection appear.
The indicated device name and the "Host Individual Address"
(individual address of the device) can be changed within your
ETS project then.
Like all programmable KNX devices the KNX IP Router 752
secure
has an individual address which can be used to access
the device. This is used, for example, of the ETS when down-
loading to the KNX IP Router via the bus.
For the interface function the device contains additional individu-
al addresses that can be set in the ETS. When a client (e.g.
ETS) sends via the KNX IP Router telegrams to the bus, they
contain a sender address as one from the additional addresses.
Each address is associated with a connection. Thus response
telegrams can be clearly transmitted to the respective client.
The additional individual addresses must be selected from the
address range of the bus line in which the interface is installed
and may not be used by another device.
Example:
Device address
1.1.0
(address within ETS topology)
Connection 1
1.1.240 (1. additional address)
Connection 2
1.1.241 (2. additional address)
Connection 3
1.1.242 (3. additional address)
Connection 4
1.1.243 (4. additional address)
Connection 5
1.1.244 (5. additional address)
Connection 6
1.1.245 (6. additional address)
Connection 7
1.1.246 (7. additional address)
Connection 8
1.1.247 (8. additional address)
The section “Individual Address” enables you to select the indi-
vidual KNX address of the currently used KNXnet/IP Tunneling
connection.
The individual KNX device address and the individual KNX
addresses for additional tunneling connections can be changed
within the ETS project, after the device has been added to the
project.
ETS database
The ETS database (ETS 5.7 or higher) can be downloaded from
the product website of the KNX IP Router 752
secure
(www.weinzierl.de) or via the KNX online catalogue.
If the first product is inserted into a project with KNX Security, the
ETS prompts you to enter a project password.
This password protects the ETS project from unauthorized ac-
cess. This password is not a key that is used for KNX communi-
cation. The entry of the password can be bypassed with "Can-
cel", but this is not recommended for security reasons.
ETS requires a device certificate for each device with KNX Secu-
rity that is created in the ETS. This certificate contains the serial
number of the device as well as an intangible key (FDSK =
Factory Default Setup Key).
