Thankyou. The Mach 2 has a USB and power running through it so I need to figure out if below the mount or the moving side is best. I'm also running headless with an industrial PC that runs at 12V. The moving part will have a PegasusAstro Powerbox with all the USBs and additional power breakouts. I like the WEMO switch idea. I also agree with Windows Remote Desktop as it just works.
