Re: 3V3 digital signal to the cRIO
If all else fails you could always make up a converter with any open collector transistor. Off the top of my head a MPSA14 or MPSA13 would work very nice to change the 3.3 to 5 volt. All you need is to drive the base with the 3.3 logic and then use a 4.7K pullup to cRIO 5 volts on the collector. Be sure to use a common ground between the PI and cRIO.
