Precharging

[jkelleyrtp]

We added some new components to our robot that are actuated with pneumatics. However, the only way we fit in the frame perimeter is with the pistons actuated, requiring air in the system. We've read up on precharging the system however we don't have an extra compressor or relay (we have 2 control systems+pcm). Our current solution is to enable the robot in queue to charge the system and then hold charge until the match starts. Is there a way we can manually enable the compressor without connecting to and enabling the robot?
