2.9.1. JP1: Keyboard Power
Type: 3 pin
Default: Pin 1 and Pin 2 Short
Some keyboards may not follow standard specifications. If you find you are hav-
ing problems with your keyboard, change the settings on JP 1. This might help
you to solve the problem.
2.8.5. Universal Serial Bus (USB) Port 1 & 2
Connector: CN 6 (USB 1)/ CN 7 (USB 2)
Type: 4 pin female
Two USB ports are available for connecting USB devices. The mainboard is also
equipped with an expansion connector that supports four additional USB
external connectors. (The USB cable is not included with the mainboard).
2.8.6. 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).
