DROVR Output on AD9914

Hi, I'm currently controlling an AD9914 eval board with an Arduino using SPI. I'm using the 9914's ramp generator to make chirps, and would like to use the DROVER-BUF to trigger a digitizer. Using the 9914 eval board software I can setup the ramp generator and get a signal from the DROVR pins. However, when I switch to Arduino control, I lose the DROVR signal. I set the same register values that the eval board software does, with DROVR output enabled, but get nothing out of the DROVR pin. I'm a bit stumped as to why this is happening and any ideas would be appreciated.
