2.3 Jumper Description
You can change the PSC-586VGA's configuration by setting jumper
switches on the board. The board's jumpers are preset at the factory.
Under normal circumstances, you should not need to change the
jumper settings.
A jumper switch is
closed
(sometimes referred to as shorted with the
plastic cap inserted over two pins of the jumper). A jumper is
open
with the plastic cap inserted over one or no pin(s) of the jumper.
Figure 2.2 below shows different jumper settings which will be used in
this chapter.
