Jumper Settings
This section provides instructions on how to configure your PCA-6011 by setting the
jumpers. It also includes the PCA-6011's default settings and your options for each
jumper.
1.8.1
How to set jumpers
You can configure your PCA-6011 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 set-
ting jumpers.
1.8.2
CMOS clear (CMOS1)
The PCA-6011 single board computer contains a jumper that can erase CMOS data
and reset the system BIOS information. Normally this jumper should be set with pins
1-2 closed. If you want to reset the CMOS data, set CMOS1 to 2-3 closed for just a
few seconds, and then move the jumper back to 1-2 closed. This procedure will reset
the CMOS to its default setting.
PCA-6011 User Manual
Always completely disconnect the power cord from your chassis
whenever you work with the hardware. Do not make connections
while the power is on. Sensitive electronic components can be
damaged by sudden power surges. Only experienced electronics
personnel should open the PC chassis.
Always ground yourself to remove any static charge before touch-
ing the boards. Modern electronic devices are very sensitive to
static electric charges. As a safety precaution, use a grounding
wrist strap at all times. Place all electronic components on a static-
dissipative surface or in a static-shielded bag when they are not in
the chassis.
The computer is provided with a battery-powered real-time clock
circuit. There is a danger of explosion if battery is incorrectly
replaced. Replace only with same or equivalent type recom-
mended by the manufacturer. Discard used batteries according to
manufacturer's instructions.
There is a danger of a new battery exploding if it is incorrectly
installed. Do not attempt to recharge, force open, or heat the bat-
tery. Replace the battery only with the same or equivalent type rec-
ommended by the manufacturer. Discard used batteries according
to the manufacturer's instructions.
