RoHS-Compliance

The EPM-14 is RoHS-compliant.

A

BOUT ROHS

In 2003, the European Union issued Directive 2002/95/EC regarding the Restriction of the use of
certain Hazardous Substances (RoHS) in electrical and electronic equipment.

The RoHS directive requires producers of electrical and electronic equipment to reduce to
acceptable levels the presence of six environmentally sensitive substances: lead, mercury,
cadmium, hexavalent chromium, and the presence of polybrominated biphenyls (PBB) and
polybrominated diphenyl ethers (PBDE) flame retardants, in certain electrical and electronic
products sold in the European Union (EU) beginning July 1, 2006.

VersaLogic Corporation is committed to supporting customers with high-quality products and
services meeting the European Union’s RoHS directive.

Warnings

Introduction

ELECTROSTATIC DISCHARGE

Electrostatic discharge (ESD) can damage boards, disk drives and other components. The circuit
board must only be handled at an ESD workstation. If an approved station is not available, some
measure of protection can be provided by wearing a grounded antistatic wrist strap. Keep all
plastic away from the board, and do not slide the board over any surface.

After removing the board from its protective wrapper, place the board on a grounded, static-free
surface, component side up. Use an antistatic foam pad if available.

The board should also be protected inside a closed metallic anti-static envelope during shipment
or storage.

Note The exterior coating on some metallic antistatic bags is sufficiently conductive to

cause excessive battery drain if the bag comes in contact with the bottom-side of
the EPM-14.

ITHIUM BATTERY

L

To prevent shorting, premature failure or damage to the lithium battery, do not place the board on
a conductive surface such as metal, black conductive foam or the outside surface of a metalized
ESD protective pouch. The lithium battery may explode if mistreated. Do not recharge,
disassemble or dispose of in fire. Dispose of depleted batteries promptly.

EPM-14 Reference Manual 4

Introduction

TRANSIENT VOLTAGE SUPPRESSION (TVS) DEVICES

The EPM-14 circuitry is protected from spike and surge damage by on-board transient voltage
suppression (TVS) devices on the user I/O signals. Figure 2 shows a typical example of TVS
circuitry.

In order for the TVS devices to function properly, they must be connected to earth
ground. This connection is made at the board’s upper right mounting hole, as shown in Figure 3.
All other m

ounting holes are floating. Use m

etal standoffs or a grounding strap to connect the

lower right mounting hole to the enclosure chassis, which should be connected to earth ground.

 IDE data cable (CBR-4406); may also require 2mm to 0.1” adapter (CBR-4405)
 Power adapter cable (CBR-1008)

You will also need a Windows (or other OS) installation CD.

Basic Setup

Configuration and Setup

The following steps outline the procedure for setting up a typical development system. The
EPM-14 should be handled at an ESD workstation or while wearing a grounded antistatic wrist
strap.

Before you begin, unpack the EPM-14 and accessories. Verify that you received all the items you
ordered. Inspect the system visually for any damage that may have occurred in shipping. Contact
[e-mail] immediately if any items are damaged or missing.

Gather all the peripheral devices you plan to attach to the EPM-14 and their interface and power
cables.

It is recommended that you attach standoffs to the board (see Hardware Assembly) to stabilize the
