generqte a PWM signal with LabVIEW using digitals outputs

ok, I have installed the last version of NI-DAQmx but it doesn't work neither. I don't understand, I can communicate with the 6070E card using the Measurement & Automation's Test panel without any problem. But it doesn't work with Labiew. I tried to configure it with DAQ assistant but I always received the same message "No supported devices found". You have to know that I use a remote system, with PXI chassis. I attached a screenshot of my MAX page, maybe you could see where I have done a mistake.
