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 computer's default settings and
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 con-
nect 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 use-
ful when setting jumpers.
1.8.2 CMOS Clear (CMOS1)
The PCA-6008 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 it to the 1-2 pin position. Avoid clearing the
CMOS while the system is on; it will damage the mainboard.
1.8.3 Watchdog Timer Output (JWDT1)
The PCA-6008 contains a watchdog timer that will reset the CPU or send a signal to
IRQ11 in the event the CPU stops processing. This feature means the PCA-6008 will
Caution! The computer is provided with a battery-powered Real-time Clock cir-
cuit. There is a danger of explosion if battery is incorrectly replaced.
Replace only with same or equivalent type recommended by the manu-
facturer. Discard used batteries according to manufacturer's instruc-
tions.
Note! Before installing your PCA-6008 into a chassis, make sure that all components
on both sides of the CPU card do not touch any metal parts, especially the
chassis wall and add-on card at the adjacent slot
