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 EP100 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, it is suggested to be
set under power-off.

2.3.5 COM1 Data/Power Selection (JP6)
The COM1 port has +5V level power capability on DCD and +12V level on RI by setting
this jumper. When COM1 is set to +5V or +12V level, please make sure the
communication mode is RS-232 (see section 2.3.6).
2.3.6 COM1 RS-232/422/485 Mode Setting (JP7, JP8, JP9)
Use these jumpers to set COM1 port to operate as RS-232, RS-422 or RS-485
communication mode. When these jumpers are set to operate as RS-422 or RS485,
please make sure COM1 is on data mode (see section 2.3.5)
2.3.7 LVDS Voltage Selection (JP10 and JP12)
The board supports voltage selection for flat panel displays. JP10 is used to set LVDS
connector (CN13) pin 1~6 VCCM to +3.3V or +5V voltage level. JP12 is used to set
LVDS connector (CN13) pin 1~6 VCCM to +12V voltage level.

2.3.8 Auto Power On (JP11)
If JP11 is enabled for power input, the system will be automatically power on without
pressing soft power button. If JP11 is disabled for 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.
2.3.9 LVDS Brightness Control Mode Setting (JP14)
The JP14 enables you to select PWM or voltage control mode for inverter connector
(CN9) pin 8. These two control modes are for adjusting LVDS brightness.
2.3.10 Restore BIOS Optimal Defaults (JP16)
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.
