Mini Rambo and RepRap smart controller

Hi, I am trying to set up a Mini Rambo 1.3+ and reprap smart controller.
What lines in the config H file need to be activated for all of the Mini Rambo functionality.
I understand that Ardurino needs to be set up for the Mini.

I have seen instructions in RepRap.wiki/mini rambo. Did not work for me.
Any help will be appreciated.

Also cannot make contact with printer from Repetier Host
