You might have one of the boards that responds to the alternate address of 0xAC instead of the default 0x3A. Try changing that in the example code and see if it starts responding.
Thank you for verifying the accelerometer works on the 8-slot cRIO. We've successfully used the accelerometer at address 0x3A with an Arduino so that does not appear to be our issue.
