I have the AD9249-65EBZ board. I do not have any of the recommended interfacing boards. I have powered the board with 6V and removed the jumpers on P1. I have attached connections to a micro-controller to the middle pins 2, 5, 8, 11. I then attempt to communicate with the board via spi and receive no response. Is there anything else that needs to be done in order to communicate with this board? 

I've attached an image of the signal I'm sending to it.
