GPIO sensor wiring - Shore Power
Monitor a Shore Power connection by connected a DC voltage that is supplied from
the AC system. This could be a simple DC mains plug, or a AC-DC Rectifier. If the AC
supply disconnects, this will cause the DC voltage connected to Cortex to drop and
generate an alarm.
