Following the Robot section of the rulebook and the Tips and Guidelines, the pressure switch that is supplied in the KOP needs to be wired back to the digital inputs of the RC. The code for control of the compressor using this device (which is required if you are using pneumatics) is part of the default RC code. If you wish to write your own control software, merely copy and paste the lines that relate to compressor control from the default software.
The switch must use only the ground and digital input when using a PWM cable for interconnect. Please remember that one wire of the PWM is connected to the backup battery and must be insulated to prevent damage or failure of the backup battery system.

<R96> The Nason pressure switch must be connected to the high-pressure side of the pneumatic
circuit (i.e. prior to the pressure regulator) to sense the “stored” pressure of the circuit. The
two wires from the pressure switch must be connected directly to a digital input and ground
terminal on the Robot Controller, and the controller must be programmed to sense the state
of the switch and operate the relay module that powers the compressor.
