The certificate is printed as text on the device. It can also be
conveniently scanned from the printed QR code via a webcam.
The list of all device certificates can be managed in the ETS
Overview - Projects - Security window.
This initial key is required to safely put a device into operation
from the start. Even if the ETS download is recorded by a third
party, the third party has no access to the secured devices af-
terwards. During the first secure download, the initial key is
replaced by the ETS with a new key that is generated individual-
ly for each device. This prevents persons or devices who may
know the initial key from accessing the device. The initial key is
only reactivated after a master reset.
The serial number in the certificate enables the ETS to assign
the correct key to a device during a download.
In the ETS, some settings are displayed in addition to the pa-
rameter dialog in the properties dialog (at the edge of the
screen). The IP settings can be made here. The additional ad-
dresses for the interface connections are displayed in the topol-
ogy view.
Each individual KNX address can be changed by clicking on the
list entry and typing in the desired address into the “Individual
Address” text-field. If the text-field frame switches to color red
after entering the address, the address is already taken within
your ETS project.
Make sure that none of the addresses above are already
present in your KNX installation.
By clicking on the KNX IP Router 752
secure
device entry within
your ETS projects topology view, an information column ‘Proper-
ties’ will appear on the right side of the ETS window. Within the
‘Settings’ overview, you can change the name of the device.
If secure tunneling is activated, a unique password will be creat-
ed automatically for each tunnel. These passwords can be dis-
played under the ‘Settings’ overview, when a tunnel is selected.
Within the “IP” overview the IP network specific options of the
KNX IP Router 752
secure
can be changed.
By changing "obtain an IP address automatically (via DHCP)" to
“Use a static IP address" (static IP address) the IP address,
subnet mask, and default gateway can be set freely.
All changes in the properties menu become effective on-
ly after a successful application download.
