1-3. SAFETY PRECAUTIONS
Follow the messages below to avoid your systems from damage:
1. Avoid your system from static electric on all occasions.
2. Keep away from the electric shock, don't touch any components of this card
when the card is on. And always disconnect power from your system when
you work off.
3. Disconnect the power when you change any configurations. Because when
you connect a jumper or install any cards, the sudden of power may damage
the electric components.

2-3 HOW TO SET JUMPERS
You can configure your board by setting jumpers. A jumper consists of two or
three metal pins with a plastic base mounted on the card, and a small plastic
“cap”( with a metal contact inside) to connect the pins. So you can set up your
hardware configuration by “open” or “close” the pins.
The jumper can be combined into sets which called jumper blocks. When the
jumpers are all in the block, you have to put them together to set up the
hardware configuration. The figure below shows how this looks.
JUMPERS AND CAPS
If a jumper has three pins, for examples, labelled PIN1, PIN2, and PIN3. You can
connect PIN1 & PIN2 to create one setting and shorting. You can either connect PIN2
& PIN3 to create another setting. The same jumper diagrams are applied all through
this manual. The figure below shows what the manual diagrams look and what they
represent.
