Jumper Conguration
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). The user may also choose to draw the
needed power from the PC’s internal system power supply via an LP4
molex connector.
