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 modules or integrated circuits from their anti-static packaging until you are
ready to install them.
Before holding the module 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 modules 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 SDM300S to meet your application purpose. Below
you can find a summary table of jumper and onboard default settings.
Note
Once the default jumper setting needs to be changed, please do it under power-off
condition.
