2.5 Main Board Jumper Settings
2.5.1 Board top view of the system main board with jumper and DIP switch
The figure below is the top view of the system main board which is the main board. It
shows the location of the jumpers and the switches.
You may configure your card to match the needs of your application by setting
jumpers. A jumper is a metal bridge used to close an electric circuit. 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” a jumper, you connect the pins with the clip.
To “open” a jumper, you remove the clip. Sometimes a jumper will have three pins,
labeled 1, 2 and 3. In this case you would connect either pins 1 and 2, or 2 and 3.
