Weinzierl KNX IP Interface 732 Secure

Let me start be stating that my knowledge on the subject is minimalistic.

I added a Weinzierl 732 secure module in ETS6. Module can be seen and is even selected as the main interface (automatic deselected and KNX IP is selected).

However when I have a further look at the connection details the device shows up under "found connections" but not under "configured connections".

When I click on the KNX IP interface under "found connections" there is another pop-up that requires a password (and optional authentication code) to commission the device.

I have no clue on the password I have to set in this menu ! Can not find a default password in the manual.

Anyone who has experience with this and can help me out ?

Many thanks in advance.
