R717      *Don’t alter the CAN bus. No device that interferes with, alters, or blocks communications among the roboRIO and the PDP/PDH, PCMs/PHs, and/or CAN motor controllers on the bus will be permitted.

Only 1 wire should be inserted into each Weidmuller CAN connector terminal. For documentation on how to wire the CAN bus connections see How to Wire an FRC ROBOT.
