3.1 Setting Jumpers and Switches
It is possible to configure the Computing Box to match the needs of the application by
resetting the jumpers. A jumper is the simplest kind of electrical 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” a jumper, connect the pins with the clip. To
“open” a jumper, remove the clip. Sometimes a jumper has three pins, labeled 1, 2,
and 3. In this case, connect either pins 1 and 2, or pins 2 and 3.
A pair of needle-nose pliers may be helpful when working with jumpers. If there are
any doubts about the best hardware configuration for the application, contact the
local distributor or sales representative before making any changes.
An arrow is used on the motherboard to indicate the first pin of each jumper.
