#23 DMX control box not working

[xirisf]

I wrote this code, I compile and updload the code to my arduino with no error, but when I try, noting happens. I tried with a GrandMa2 console connected to input and it doesn't received nothing. Also tried directly to the splitter and dimmers but nothing. what I'm doing wrong? What can I do to make it work?
