All devices receiving power from the same source, supplied by the voltages required for each of them taking into account possible voltage drops produced by the length of the wiring, that on occasions it can measure up to one hundred meters, Since both data and power travelling through the same cable thus reducing the time and resources needed.
Vifaa vyote kupokea nguvu kutoka kwa huyo chanzo, hutolewa na ya voltages zinazohitajika kwa ajili ya kila mmoja wao kuzingatia voltage inawezekana matone zinazozalishwa na urefu wa wiring, kwamba katika matukio ni kupima hadi mita mia moja, Tangu data na nguvu kusafiri kupitia waya huo hivyo kupunguza muda na rasilimali zinazohitajika.
