Jumper Conguration
The card is specially designed to allow power output from the ninth pin of the
connector to enable power up of the connected devices without the use of a power
adapter. The card allows user to set each individual port with 5V, 12V, or RI (no power)
via jumper settings on the card. The user may also choose to draw the needed power
from the PC’s internal system power supply via an LP4 molex connector.
