2-3. HOW TO SET THE JUMPERS
You can configure your board by setting the jumpers. Jumper is consists of
two or three metal pins with a plastic base mounted on the card, and by using
a small plastic
"
cap
"
, Also known as the jumper cap (with a metal contact
inside), you are able to connect the pins. So you can set-up your hardware
configuration by
"
opening
"
or
"
closing
"
pins.
The jumper can be combined into sets that 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 like.
JUMPERS AND CAPS
If a jumper has three pins for example, 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.
