9.5 Power UP/DOWN Option (only software)
The Power UP/DOWN option modifies the signal receive function for the signals
present at the telemetry connector.
RF section on / off control signals are treated as control signals for RF output
power level to allow for UP/DOWN setting.
The UP or DOWN command is provided by switching the corresponding signal at
the connector to ground for at least 500mS (pin features internal pull-up to power
supply).
