@RIDGE FORRESTER Welcome! Thank you for your topic. If I understand correctly, you are trying to install our hardware for the first time? The first photo is a photo of an analog TV connection. This isn't the correct connection point for our Experiabox.
You should have another connection point in your house. The connection points are called ‘ISRA’.  You can find many pictures of them on Google. Normally these connection points are located in your fuse box area or in the living room. You should be able to connect the ISRA to the Experiabox with the cable supplied by us. 

If you need any more support, please let me know. 

You’ll probably have a connection like this one.

Sorry, this page is not in English, but in Dutch.

@RIDGE FORRESTER We haven't heard from you anymore, so I assume meanwhile you were able to install everything properly. If not, please let us know or give a call to one of my colleagues (0800-0402 FREE)
