The Pneumatic Control Module (PCM) takes care of the compressor automatically. In LabVIEW, all you need to do is open a solenoid, and everything else is handled for you. Just connect the compressor power and the pressure switch to the labeled Weidmuller connectors on the PCM, and you'll be good to go.

For shifting gears with LabVIEW, you need to pipe pneumatic tubing to the right places, and you need to wire the solenoid valves to the right connectors on the PCM. Then you need to Open the solenoids appropriately, and you need to Set them appropriately when you want to shift gears. The programming depends on a couple of things. Are you using single solenoids (only one pair of wires) or double solenoids (a pair of wires at each end)? What physical control (gamepad or joystick button, computer keyboard, foot switch, etc.) are you using to command the gear?
