If you mean the Maxbotics EZ1 sonar, then that's what we used last year to hug the track divide and it was GREAT.

It's an analog input so you need to feed it into the Analog Bumper. Read the input voltage and divide by 0.0098 to get inches (9.8mV / inch). You will probably need to filter the input because the cRIO seems VERY noisy.
