Digital Output 6052E BNC-2111

I am trying to generate digital signal using 6052E DAQ and BNC-2111. I used NI-MAX test panel to make sure that I can generate Digital output using this DAQ and BNC, but the problem is that the output of the channels do not change when I set them from Low to High. I am trying to control a 4 way relay with this DAQ so I need 4 different DOs. I can use the 2 AO to simulate DO. The problem is that PFI0, CTR1, AO EXT REF, AO 0 and AO 1 are always 0 Volt and PFI2, PFI7 and CTR 0 are always 5 Volt.
