Jumpers and Connectors

Connectors on the PCA-6782 single board computer link it to external devices such
as hard disk drives and a keyboard. In addition, the board has a number of jumpers
used to configure your system for your application.
Below, Tables 1.1 and 1.2 list the jumper and connector functions. Later sections in
this chapter give instructions on setting jumpers. Chapter 2 gives instructions for con-
necting external devices to your single board computer.
