Hi Jeff
It works finally. Was not problems of software, or firmware or something else. I just tried to unplug the card from RAB2 module, and carefully plug it again, and like a miracle it was going working, either in input and output. So I think was a ploblem about pins conctat, also I cared very much for insert. Thank you very much and I hope that experience can help everybody for all those will have same issues.
