to operate the unit with an external power supply, instead of Port Power.
The mating connector for J5 is Molex 51021-0300.
J5-1 is connected to the positive terminal of a filtered DC external power supply (often marked +
or Pos. The voltage should be between +5 VDC and +15 VDC. If J4-3 is still connected to the
port and it is desired that the power come from the external power supply, the voltage at J5-1
must exceed the voltage at J4-3, or the Reader will continue to take power from the port.
J5-2 should be connected to the Power Supply Ground Return (often marked – or Neg).
