1.8 Jumper Settings
This section provides instructions on how to configure your card by
setting jumpers. It also includes the card's default settings and your
options for each jumper.
1.8.1 How to set jumpers
You configure your card to match the needs of your application by
setting jumpers. A jumper is the simplest kind of electric switch. It
consists of two metal pins and a small metal clip (often protected by a
plastic cover) that slides over the pins to connect them. To “close” (or
turn ON) a jumper, you connect the pins with the clip. To “open” (or
turn OFF) a jumper, you remove the clip. Sometimes a jumper
consists of a set of three pins, labeled 1, 2 and 3. In this case you
connect either pins 1 and 2, or 2 and 3.
A pair of needle-nose pliers may be useful when setting jumpers.
