What's odd is I was using codes I had learned into a C4 system that I know for a fact worked with the exact same model X1 box. I was trying to update an old Sonance K2 keypad (which is RTI software) and I couldn't even paste some of the codes into the IR library. A few of them kicked out some error about "too many timing signals" which I had never seen before in all the years we did RTI.
