I had to translate it into my native language in order to understand the Manual written by Hans.
I agree with him when he says in the Manual that you should read it and not be a HERO, that you will be able to install and use it yourself.
After reading it, you will see the world differently.
Unfortunately, this is typical of most technical people, who first try to solve it with their own logic.
After it didn't go the way you envisioned, you read how it should have been done.
So I recommend that users read the manual, because they will learn a lot from it.
It not only describes how it should be built, but also details of the operation, what it does and why.
I still don't have QDX, but I'm learning a lot from the posts. You just have to choose well. ;-)
