1.8 Jumper Settings
This section provides instructions on how to configure your single board
computer by setting the jumpers. It also includes the single board com-
puter's default settings and your options for each jumper.
1.8.1 How to set jumpers
You can configure your single board computer to match the needs of your
application by setting the jumpers. A jumper is a metal bridge that closes
an electrical 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” (or turn ON) a jumper, you connect the pins with the
clip. To “open” (or turn OFF) a jumper, you remove the clip. Sometimes
a jumper consists of a set of three pins, labeled 1, 2, and 3. In this case
you connect either pins 1 and 2, or 2 and 3. A pair of needle-nose pliers
may be useful when setting jumpers.
1.8.2 CMOS clear (J1)
The PCA-6190 single board computer contains a jumper that can erase
CMOS data and reset the system BIOS information. You can clear
CMOS by shorting 2-3 pin while the system is off. Then return to 1-2 pin
position. Avoid clearing the CMOS while the system is on; it will damage
the mainboard.
