ELETTRONICA

  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).

Configuration of DB15F telemetry connector (Remote):
