Bundled Cable and Computers

I have seen videos of people turning on wires from bundled cable (example - lime on) but not being able to turn them off (example - lime off) because they say to do that they need to reboot their computer.. Is there a command to turn the power going to the wire off so I wouldnt have to reboot the computer? (example as I said before (lime off). Sorry if this is a newb question but im only about a week new to this but im still learning :)/>/>. I would be using this to power/unpower different things from one computer.

Thanks for the help guys

basically you set the output for every colour every time you want to change the output at all. example

rs.setBundledOutput(side,colors.white) --activates white wire
sleep(1)
rs.setBundledOutput(side,colors.blue) --turns on blue and turns off white because you did not include it here
