GNU Radio FMCOMMS2 Receiver

I'm trying to test a couple of QPSK receiver implementations on ZC706 and FMCOMMS2 boards for research, I'd like to test QPSK receive in GNU Radio (I know GNU Radio isn't fast enough to provide proper QPSK transmition). I run GNU Radio on Ubuntu and connect with board through ethernet to get the best performance, I made a simple transceiver chain but I'm concerned about its configuration. Without usage of hardware simulation is flawless, but when I try to run it on real device I can't receive simple message.

 

How should I configure FMCOMMS2 source to get the best results? Right now I  implement both transmit and receive chains to test it, but in the final result I wanna use only receive part and see its performance with external source of QPSK signal.
