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 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 CAPA830 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.

Pin 1 connects anode(+) of LED and pin 5 connects cathode(-) of LED. The power LED
lights up when the system is powered on.
External Speaker and Internal Buzzer
Pin 2, 4, 6 and 8 connect the case-mounted speaker unit or internal buzzer. While
connecting the CPU board to an internal buzzer, please set pin 2 and 4 closed; while
connecting to an external speaker, you need to set pins 2 and 4 opened and connect the
speaker cable to pin 8(+) and pin 2(-).
Power On/Off Button
Pin 9 and 10 connect the power button on front panel to the CPU board, which allows
users to turn on or off power supply.
System Reset Switch
Pin 11 and 12 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.
