1.4 Jumpers and Connectors
Connectors on the PCA-6005 board 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. The tables
below list the function of each of the board jumpers and connectors. Later
sections in this chapter give instructions on setting jumpers. Chapter 2
gives instructions for connecting external devices to your card.
