I2C Rangefinders not working

The documentation for the rangefinders is right here http://www.maxbotix.com/documents/I2..._Datasheet.pdf
,as well our Rangefinder code:



Any help we can get is much appreciated, thanks

Do you have pull down resistors on the data and clock wires? I believe the arduinos have them built into the board while the roborio needs them added to the bus.
We are using a similar sensor. I'd be happy to send you our C++ library for it.
Also, be careful if you are usng more than one. They can interfere with each other if the readings are sequenced properly.
