ESD Precautions
Computer boards have integrated circuits sensitive to static electricity. To prevent chipsets
from electrostatic discharge damage, please take care of the following jobs with precautions:
Do not remove boards or integrated circuits from their anti-static packaging until you are
ready to install them.
Before holding the board or integrated circuit, touch an unpainted portion of the system
unit chassis for a few seconds. It discharges static electricity from your body.
Wear a wrist-grounding strap, available from most electronic component stores, when
handling boards and components.

2.3 Jumper and Switch Settings
Jumper is a small component consisting of jumper clip and jumper pins. Install jumper clip on 2
jumper pins to close. And remove jumper clip from 2 jumper pins to open. Below illustration
shows how to set up jumper.
Properly configure jumper and switch settings on the CAPA318 to meet your application
purpose. Below you can find a summary table of jumpers, switch and onboard default settings.
Note
Once the default jumper or switch setting needs to be changed, please do it under
power-off condition.

2.3.1 LVDS +3.3V/+5V/+12V Voltage Selection (JP1)
This is a 2x3-pin (pitch=2.0mm) jumper. The board supports voltage selection for flat
panel displays. Use these jumpers to set LVDS connector (CN5) pin 1~6 VCCM to +3.3V,
+5V or +12V. To prevent hardware damage, before connecting please make sure that
the input voltage of flat panel is correct.
2.3.2 Restore BIOS Optimal Defaults (JP2)
This is a 1x3-pin (pitch=2.0mm) jumper. Put jumper clip to pin 2-3 for a few seconds then
move it back to pin 1-2. Doing this procedure can restore BIOS optimal defaults.
2.3.3 Auto Power On (SW1)
If SW1 is enabled for power input, the system will be automatically power on without
pressing soft power button. If SW1 is disabled for power input, it is necessary to
manually press soft power button to power on the system.

Universal Serial Bus (USB) connector for installing versatile USB 2.0 compliant interface
peripherals.
2.4.2 Front Panel Connector (CN2)
Power Status
Pin 1 and pin 2 are for power status button; letting user know the power status of this
board.
Power LED
Pin 4 connects anode (+) of LED and pin 3 connects cathode(-) of LED. The power LED
lights up when the system is powered on.
Power On/Off Button
Pin 5 and 6 connect the power button on front panel to CPU board, which allows users to
turn on or off power supply.
System Reset Switch
Pin 7 and 8 connect the case-mounted reset switch that reboots your computer without
turning off the power switch. It is a better way to reboot your system for a longer life of
system power supply.
HDD Activity LED
This connection is linked to hard drive activity LED on the control panel. LED flashes
when HDD is being accessed. Pin 9 and 10 connect the hard disk drive to the front panel
HDD LED, pin 9 is assigned as cathode(-) and pin 10 is assigned as anode(+).
