Thanks for your quick reply CoolP, I appreciate that very much!

I enjoy it much more when entering the coordinates by hand also. Since I was reading the Docs and tinkering with the system to find out how it works in detail, I stumbled upon the ADC (cards). Indeed it works when I add a 2nd ADEU. But I don´t know if this is intended to be like this or if this is a Bug. It doesn´t bother me really, since I enter them by hand also. I was just curious if I am doing something wrong. But maybe the Remote buttons do not work with ADC (cards) in reality too. Who knows.
