LAN Controller V3 malfunctioning?

[wilkxt]

The vendor told me to return the controller to change it, but he still insists that if I supply the board from the DC Jack, the voltage displayed in the Status panel will be erroneous.
It is this correct, if I energize the board from the DC jack, the voltage displayed in the status panel will be different from the real one?

No, power from DC jack or POE measur voltage is OK, only you need upgrade firmware to version 1.46(It will be available next week on this forum), becouse previous version has bug and vcc measur was overpriced about 1V.
