Preface

FCC Class A

This equipment has been tested and found to comply with the limits for a Class A digital
device, pursuant to part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when the equipment is operated in a
commercial environment.

This equipment generates, uses, and can radiate radio frequency energy and, if not
installed and used in accordance with the instruction manual, may cause harmful
interference to radio communications. Operation of this equipment in a residential area is
likely to cause harmful interference in which case the user will be required to correct the
interference at his own expense.

Installation Suggestions

Ensure you have a stable, clean working environment. Dust and dirt can get into compo­nents and cause a malfunction. Use containers to keep small components separated.

Adequate lighting and proper tools can prevent you from accidentally damaging the
internal components. Most of the procedures that follow require only a few simple tools,
including the following:

A Philips screwdriver
A flat-tipped screwdriver
A grounding strap
An anti-static pad

Using your fingers can disconnect most of the connections. It is
recommended that you do not use needlenose pliers to disconnect connections as these
can damage the soft metal or plastic parts of the connectors.

Handling Precautions

1. Always disconnect the unit from the power outlet whenever you are installing or fixing
a component inside the chassis.

2. If possible, always wear a grounded wrist strap when you are installing or fixing
a component inside the chassis. Alternatively, discharge any static electricity by
touching the bare metal chassis of the unit case, or the bare metal body of any other
grounded appliance.

3. Hold electronic circuit boards by the edges only. Do not touch the components on the
board unless it is necessary to do so. Do not flex or stress the circuit board.

4. Use the correct screws and do not overly tighten them.

5. Keep the original packaging and static-protective bag in case the unit has to be
returned.

Chapter 2 Jumper Setting

Embedded Board Computer EBC 320 Series User’s Manual

This chapter of the User’s Manual describes how to set jumpers.

Note: The procedures that follow are generic for all EBC 320 series.

2.1 Before You Begin

Ensure you have a stable, clean working environment. Dust and dirt can get into compo­nents and cause a malfunction. Use containers to keep small components separated.

Adequate lighting and proper tools can prevent you from accidentally damaging the
internal components. Most of the procedures that follow require only a few simple tools,
including the following:

A Philips screwdriver
A flat-tipped screwdriver
A set of jewelers Screwdrivers
A grounding strap
An anti-static pad

Using your fingers can disconnect most of the connections. It is recommended that you
do not use needle-nosed pliers to disconnect connections as these can damage the soft
metal or plastic parts of the connectors.

Before working on internal components, make sure that the power is off. Ground yourself
before touching any internal components, by touching a metal object. Static electricity
can damage many of the electronic components. Humid environment tend to have less
static electricity than dry environments. A grounding strap is warranted whenever danger
of static electricity exists.

•

•

•

•

•

2.2 Precautions

Computer components and electronic circuit boards can be damaged by discharges of
static electricity.

Working on the computers that are still connected to a power supply can be extremely
dangerous. Follow the guidelines below to avoid damage to your computer or yourself:

Always disconnect the unit from the power outlet whenever you are working inside the
case.

If possible, wear a grounded wrist strap when you are working inside the computer
case. Alternatively, discharge any static electricity by touching the bare metal chassis
of the unit case, or the bare metal body of any other grounded appliance.

Hold electronic circuit boards (such as the EBC 320 board) by the edges only. Do
not touch the components on the board unless it is necessary to do so. Don’t flex or
stress the circuit board.

Leave all components inside the static-proof packaging that they shipped with until
they are ready for installation.

Use correct screws and do not over tighten screws.

Chapter 2 Jumper Setting

Embedded Board Computer EBC 320 Series User’s Manual

2.3 Setting Jumpers

A jumper is the simplest kind of electric switch. It consists of two metal pins and a cap.
When setting the jumpers, ensure that the jumper caps are placed on the correct pins.
When the jumper cap is placed on both pins, the jumper is SHORT. If you remove the
jumper cap, or place the jumper cap on just one pin, the jumper is OPEN. Please see the
following illustrations

The illustrations on the right
show a 2-pin jumper. When the
jumper cap is placed on both
pins, the jumper is SHORT. If you
remove the jumper cap, or place
the jumper cap on just one pin,
the jumper is OPEN.

Open (Off) Short (On)

These illustrations show a 3-pin
jumper. Pins 1 and 2 are SHORT.
