Chapter 4. Startup and Shutdown
4.1. Startup
When connecting power to Armadillo-IoT G3, the start mode changes depending on the slide switch on the USB serial
converter. For details, refer to Section 3.5, “Slide Switch Configuration”. This section shows an example when maintenance
mode is selected. When auto boot mode is selected, the startup completes without requiring any input.
