Hello I'm assuming Ken. GitHub is not the place to get support, especially for hardware. The first place to try is the reseller you purchased from if this is something you purchased ready-to-run. The next place, and the preferred option for most issues is our Discord (https://dcc-ex.com/support/index.html#contact-support-options). There is also the "DCC-EX, DCC++, and Arduino" Facebook Group as a last option. When posting, you are going to have to post a LOT more than a 10 word description of your problem that lists what a "unit" is, (Mega DIY, RTR EX-CSB1, etc.) what you mean by "switch on", how you are connected, what power supply, what kind of display, what power indication you see such as LEDs on your command station board, preferably provide a picture showing your setup, what steps you took, what you expected, if you followed the troubleshooting steps on the web page, if you connected a serial monitor to check the configuration and boot up log, tried to re-install with EX-Installer, etc. Hope to see you on Discord! - Fred
