Unfiltered DC power from an external power supply
through the J3 Molex connector.
The NTx-Pro generates all internal power rails from
the PWR signal. A resident common mode filter
allows the input to be unfiltered, directly from a
switching wall plug power supply.
NOTE! If you implement this option, do not use VIN
as a supply.
