Quick References for Jumpers
In this manual, the terms closed and on are used when referring to jumpers
(or jumper pins) that are active; open and off are used when referring to
jumpers (or jumper pins) that are inactive. See the
Figure 2-1
for examples of
on and off pins and jumpers. The square pin in the diagram is Pin 1.
Jumpers and pins are connected by slipping the blue plastic jumper connector
overtop of two adjacent jumper pins (indicated by
1-2
or
2-3
). The metal rod
inside the plastic shell bridges the gap between the two pins, completing the
circuit. See
Figure 2-2
for more examples of pin connections.
The tables and maps on the following pages will help you set the jumpers for CPU
speed, Infrared, and external connector pin assignments, among others. The
miniature motherboard maps will help you locate the jumpers on your board. A
full-page map of the motherboard can be found on the next two pages.
