Frequently Asked Questions

Why do I have no power when plugged into the RoboRio MXP Port?
This case can occur when one of the MXP Expansion sets of pins has become shorted. An indication of this case is that the POWER led on the RoboRIO will go red, indicating a short on one of it’s power rails.

To resolve this issue, inspect each set of Expansion IO pins, and look for a ground pin being shorted to either a power or a signal pin.

To protect against accidental shorts, Kauai Labs recommends a protective enclosure that at least partially encases the MXP I/O pins, such as the such as the “lid”-style enclosure created for the navX-MXP.
