Ethernet Power Selection
Unlike the RT-PoE3N model, there are no jumpers required to set which conductors
provide power. The unit contains two separate power paths for pair 1,2 / 3,6 and for pair
4,5 / 7,8. These have the standard full wave bridge so any polarity is accepted. The
voltage measurement function accommodates either polarity and can be used to validate
the expected PSE port polarity.
