Digital Input
You can use the green wire to connect Pin 4 to a digital input to detect the state of a
switch, 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.
The primary digital input of Pin 4 on the power connector can be used to wake the router
from standby.
