AirLink OS gives you options for managing router power usage, depending on your application and hardware configuration. For example, you can use the settings at System > MCU > Voltage Threshold and System > MCU > Power Management to configure the router to enter standby mode based on a low voltage threshold, the state of the ignition switch, or an I/O input, or configure it to operate only at certain times of day.
The RESUME VOLTAGE must be higher than STANDBY VOLTAGE by more than 0.5 V. For example, if you set the Resume Voltage to 12 V, the highest number you can set for the Standby Voltage is 11.4 V.
Exercise caution when setting the Voltage Thresholds. Before setting the Resume Voltage, ensure that you have a power source readily available that can supply the configured voltage. The reset button is not available when the router is in standby mode, so you cannot use it to reset the router to factory default settings.
Under Power Management, you can configure the router to enter standby mode and resume operating based on the ignition switch (for mobile installations), an I/O connection, or a timer.
To edit an Ignition source:
To edit an I/O source:
Click Edit ( ) in the table on the row for Source > Primary IO. The Edit Source page appears.
Enable/disable the Power Source.
Select the delay (in seconds) between the I/O state change and the router entering Standby mode.
Set which logical state of the GPIO makes the router enter or exit standby mode. If set to Active High, the router remains on while the GPIO is high and enters standby when the GPIO is low. If set to Active Low, the router remains on while the GPIO is low and enters standby when the GPIO is high.
To edit a Timer source:
Click Edit ( ) in the table on the row for Source > Timer. The Edit Source page appears.
Enable or disable the Power Source.
Select a time PERIOD, which sets how often the router wakes up from standby mode.
Select an OFFSET in minutes. This sets how long after the hour the router wakes up from standby mode.
Select a DURATION. This sets how long the router operates before returning to standby mode.
