No  DAC output in AD9959

Question

Hello AD community! 
 I am using the AD9959 board. My problem: I get output signal only from the DAC FILTER OUT, but no signal from the DAC OUT (this happens in each of the 4 available channels). I know that these output pins are complementary. How can I control (using the AD9959 Evaluation software) the fraction of output signal in each of the two complementary output pin? 
 Thank you so much in advance for any input.

Hi, 
 The default configuration for the AD9959 evaluation board is to have an output at DAC FILTER OUT. You have to transfer the 0 ohm resistors if you want to have your output at DAC OUT. The output for DAC OUT is not filtered. 
 For, 
 DAC0: Transfer R25 to R24 
 DAC1: Transfer R22 to R23 
 DAC2: Transfer R72 to R28 
 DAC3: Transfer R27 to R26 
 Best regards,
