In case of using external power source, inputs must be configured by JP2 - JP5 jumpers. The configuration must be done before powering up the UniPi.
In case of using external power source, inputs must be configured by JP2 - JP5 jumpers. The configuration must be done before powering up the UniPi.
Using the external power supply and proper jumper configuration provides galvanic isolation for its inputs.
