2-2-1. How to Set Jumpers
You can configure your board by setting the jumpers. A jumper 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.
Jumpers can be combined into sets that called jumper blocks. When jumpers are all in
the block, you have to put them together to set up the hardware configuration. The
figure below shows what this looks like.
Jumpers & 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.
