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.

2.5 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 CAPA55R to meet your application
purpose. Below you can find a summary table of jumper, switch and onboard default settings.
Note
Once the default jumper or switch setting needs to be changed, please do it under
power-off condition.

2.5.1 LVDS/eDP Voltage Selection (JP1)
This is a 2x3-pin (pitch=2.0mm) jumper. The board supports voltage selection for flat
panel displays. Use JP1 to set LVDS/eDP connector (CN3/SCN1) VCCM pin to +3.3V,
+5V or +12V voltage level. To prevent hardware damage, before connecting please make
sure that input voltage of the flat panel is correct.
2.5.2 Restore BIOS Optimal Defaults (SW1)
Use SW1 to clear CMOS. Press the tact switch for at least 1 second to restore BIOS
optimal defaults.
2.5.3 Auto Power On (SSW1)
If SSW1 is enabled for power input, the system will be automatically power on without
pressing soft power button. If SSW1 is disabled for power input, it is necessary to
manually press soft power button to power on the system.
