9.5 UP/DOWN Power option (software only)
The UP/DOWN Power option modifies the function of receiving signals present
on the telemetry connector.
Specifically, the on and off control signals of the RF section become control signals
of the emitted RF power level, allowing UP/DOWN adjustment.
The UP or DOWN command is provided by connecting the relative signal on the
connector to ground for at least 500mS (the pin has an internal pull-up towards
the power supply).
Configuration of the DB15F telemetry connector (Remote):
