2.7.6. Audio/Game Port Connector
Connector:
CN 18
Type:
15 pin female
The Game/MIDI port connector is a dual purpose connector. It can either be used to connect
a joystick to the computer for game participation, or it can be used to attach an external
MIDI device. All these motherboards have 3D audio interfaces onboard.
Jumpers are built on the mainboard to allow the user flexibility to configure the mainboard
settings to meet their specific requirements. These mainboards have both two pin and three
pin jumpers.
If a two pin jumper has a jumper cap on it we say that it is short. If there is no Jumper cap
we say it is open. On a three pin jumper if a jumper cap is inserted on pins 1 and 2 we say
PIN 1
and
PIN 2
are
SHORT
. When the jumper cap is inserted on pin 2 and 3, we say
PIN
2
and
PIN 3
are
SHORT
(see the diagrams below).

This jumper allows you to select the voltage that is supplied to USB 1 and USB 2. You have
two choices: 5 V (pin 1 and pin 2 short) or standby 5 V (pin 2 and pin 3 short). Some USB
devices may not follow the standard USB power specifications. If you are using such a de-
vice it may unstable. If you do experience problems try to change the setting on JP 2. This
might help solve this problem.
