Can NI-USB-6221 Be configured for 3.3V Logic Levels

[BruceAM]

I have been tasked to test a pre-existing PCB design using LabView and a NI-USB-6221.  I have generated the code which provides the necessary signal except for one thing.  The Unit Under Test must have 3.3V logic levels instead of the 5V logic levels at the output of the NI-USB-6221.  Is there a way to configure the NI-USB-6221 to use 3.3V logic levels on it's Digital Input and Output ports?

Thank you for your time and assistance.

In a word no.  However, you can install a logic level shifter between the DAQ and the UUT http://focus.ti.com/docs/prod/folders/print/sn74lvc4245a.html is a good part to consider

Jeff,  

Though your response was not what I wanted to hear, I do thank you for your input and knowledge.  I now know what direction I must travel in order to interface the NI-USB-6221 to my UUT. 

Thanks Again

Glad to help.  Sorry I can't change the laws of physics for you.
