No DAQ Assist Icon on Labview

Hi,

First of all, I am pretty new,　I have never used NI's system.
I am trying to capture the Digital signals via USB-6366 on Labview. However I can not see the DAQ assist icon on Labview.

I believe this USB-6366 is recognized on MAX, and see digital signals via Test Panels.
How to come up the icon on Labview?

My ultimate goal is to capture digital signals and put into DSP(like Low Pass Filter and so on).

Thanks,
