4.1 Setting Jumpers and Switches
It is possible to configure the In-Vehicle 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.
