Power Supply for R3328B
External Power Supply – the board can be powered with a +12V external power supply though a locking DC connector on the back panel. The rear +12V DC jack accepts locking plugs with an inner diameter (ID) of 2.5 mm and an outer diameter (OD) of 5.5 mm, where the inner contact is +12V and the shell is GND.

Internal Power Supply – the board can alternatively be powered via the internal +12V DC 1 x 2 power connector, where pin 1 is GND and pin 2 is +12V VDC. The internal 1 x 2 power connector is a Molex 5566-2 header which accepts a Molex 5557-02R connector from the power supply.

Caution: There is no isolation circuitry between the external +12V DC jack and the internal 1 x 2 power connector. It is the system integrator's responsibility to ensure no more than one power supply unit is or can be attached to the board at any time and to ensure the external +12V DC jack is covered if the internal 1 x 2 power connector is to be used.
