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.

2.4 Jumper 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 settings on the PICO121 to meet your application purpose. Below you can find a summary table of all jumpers and onboard default settings.
Note
Once the default jumper setting needs to be changed, please do it under power-off condition.

2.4.1 LVDS +12V Voltage Selection (JP1) (Optional)
The board supports voltage selection for flat panel displays. Use JP1 to set LVDS connector (CN8) pin 1~6 VCCM to +12V. To prevent hardware damage, before connecting please make sure that the input voltage of flat panel is correct.
2.4.2 Auto Power On (JP2)
If this jumper is enabled for AC power input, the system will be automatically power on without pressing soft power button. If this jumper is disabled for AC power input, it is necessary to manually press soft power button to power on the system.
Note
This function is similar to the feature of power on after power failure, which is controlled by hardware circuitry instead of BIOS.
2.4.3 LVDS +3.3V/+5V Voltage Selection (JP3)
The board supports voltage selection for flat panel displays. Use JP3 to set LVDS connector (CN8) pin 1~6 VCCM to +3.3V or +5V. To prevent hardware damage, before connecting please make sure that the input voltage of flat panel is correct.
2.4.4 LVDS Brightness Control Mode Setting (JP4)
This jumper enables you to select PWM or voltage control mode for inverter connector (CN10). These two control modes are for adjusting the brightness of LVDS panel.

RCC is a Remote Control Controller for DASH function. Use this jumper for updating RCC firmware via SWIM interface, see section 2.5.8 for CN11.
2.4.7 Restore BIOS Optimal Defaults (JP7)
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.
