Here are the frequently asked questions to the product.
Also have a look at the KUNBUS-FNL landing page.
Is it possible to downgrade the FNL firmware?
No this is unfortunately not possible.
I need a Certificate of Origin. Where can I find this document?
You can download the document here.
I cannot find my FNL on the network how can I access it?
With the tool “TMG Setup” you may access the device using the symbolic name.
This tool works from firmware version 5.02
Choose „Start → Programme → TMG Net Series → TMG Setup“. There will be shown an overview of the configured FNLs. If you never configured a FNL, the list will be empty.
See chapter “Name declaration for a FNL with TMG Setup” in the user manual.
