While it makes the NXT motors and sensor ports clear, it doesn't say how the controllers are set up

EDIT: Nevermind, should have thought to look at the sample code. For anyone curious, it's motor-motor-motor on sensor port 1.

Just for future reference: you can always view the current configuration of the robot's sensors and motors by navigating to the Motors and Sensors Setup window (under the Robot menu) and select either the Motors tab, Sensors tab, External Controllers tab (for MATRIX and TETRIX controller configurations) or (if using a standard model) the Standard Models tab.
