Jumper Settings and Connectors
4.1 Setting Jumpers
The Vehicle Mounted Computer can be configured to match the needs of
each application by setting 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), which slides over the pins to close the
circuit and 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, it is possible to connect either pins 1
and 2 or pins 2 and 3 to each other.
A pair of needle-nose pliers may be helpful when working with jumpers.
If there are any doubts about the best hardware configuration for a partic-
ular application, contact the local distributor or sales representative
before making any changes.
An arrow is printed on the motherboard to indicate the first pin of each
jumper.
