The figure below is the top view of EVS-2000 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.
