Battery power management

When the TX54 device is used in a vehicle, Digi recommends that you use the ignition sense line. This
allows the device to properly shutdown when the vehicle is turned off. By default, the TX54 device
automatically powers on when it detects power on the ignition sensor, and powers off when it detects
that there is no power on the ignition sensor, and there is no delay for either power on or power off
based on the power ignition sensor.
You can configure delays for powering on or off the system based on the state of the ignition sensor.
