Enable PWM output and use DAC at the same time

Hi,

I am using the U3-HV labjack module  using the following configuration: PWM output on FIO5 and also using DAC1. 

I need them to be independent, but i see that the PWM output somehow infulences the DAC1 output. Is there a way to configure the PWM output as well the DAC to use them independently ?

any suggestions, greatly appreciated.

PS: Tried using one of the digital outputs and toggling them with time.sleep(): but can't get the resolutions i am looking for (need to generate the pwm at ~75Hz)
