This article describes how to use the Input and Output General Purpose I/O pins available as part of the power plug.
Input Pin – Select one of the following options from the drop-down menu:
In this mode, the input pin is not used.
In this mode the logic state (high or low) is automatically sensed
by the router and is readable as the Current Value.
In this mode, an external device can reset the router by holding
the input low for 10-seconds.
Output Pin – Select one of the following options from the dropdown menu:
In this mode, the output pin is not used and is at
0V (ground potential).
Set High/Router Running:
In these modes, the output pin is logic low while the router is
booting and transitions to logic high when the router is fully
running. If the router is reset, the output returns to low until
the router has fully rebooted.
In this mode, the output pin is logic low until the modem has
connected to the tower. If the connection drops, this output
is set low until the connection is restored.
*NOTE: Red – Positive, Black – Negative, Orange – Input, Blue – Output (Click here for a more detailed description.)
