3-4. HOW TO SET 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 it looks.

JUMPERS AND CAP
If a jumper has three pins, for example, labeled PIN1, PIN2, and PIN3, you can either connect PIN1 & PIN2
to create one setting and shorting or connect PIN2 & PIN3 to create another setting. The jumper setting
rules are applied throughout this manual.
