    USB Jack Power The two type B USB jacks on the PK-232SC default power output is 5 Volts @ 100 mA. This power is derived from the computer or powered USB hub upstream from the PK-232SC. If the jumper on JP5 is connected between pins 2 &3 (factory default), the external power supply will not be connected.
