Digital Input

Digital input is available on Pin 4 on the power connector and on Pins 2, 3, 6, and
7 on the auxiliary I/O connector.
You can connect any of these pins to a digital input to detect the state of a switch
such as a vehicle ignition, or to monitor an external device such as a motion
detector, a remote solar panel, or a remote camera. Digital input can also be used
with the standby timer.
