Introduction
EPM-32 Reference Manual 4
RoHS Compliance
The EPM-32p, t, and v are RoHS-compliant.
ABOUT 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
ELECTROSTATIC DISCHARGE
Warning! Electrostatic discharge (ESD) can damage circuit 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 product,
and do not slide it over any surface.
After removing the product from its protective wrapper, place it on a grounded,
static-free surface,. Use an antistatic foam pad if available.
The product 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-32.
LITHIUM BATTERY
Warning! To prevent shorting, premature failure or damage to the lithium battery, do not
place the EPM-32 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 used batteries promptly and in an environmentally suitable manner.

Introduction
EPM-32 Reference Manual 5
CONNECTING THE NORTH BRIDGE AND SOUTH BRIDGE BOARDS
Warning! When connecting the north bridge and south bridge boards of the EPM-32, you
must be sure that sockets JN5 and JN6 on the north bridge board mate perfectly
with headers JS2 and JS3 of the south bridge board. Failure to connect the boards
properly could cause serious damage and void the warranty.
See Connecting the North Bridge and South Bridge Boards on page 14.

EPM-32 Reference Manual 7
Configuration and Setup
Initial Configuration
The following components are recommended for a typical development system.
EPM-32 Two Board Set (CPU Module & I/O Module)
200-pin SODIMM DDR200, DDR266 or DDR333
ATX Power Supply
SVGA Video Monitor
Keyboard and Mouse with PS2 Connector
IDE Hard Drive
IDE CD ROM Drive
The following VersaLogic cables are recommended. These cables are included in the
development cable kit (CKR-CHEE) that ships with the EPM-32.
CBR-1008 –ATX Adapter Cable
CBR-1201 –Video Cable
CBR-8001 –Standard I/O Breakout Cable
CBR-4406 –IDE Data Cable
CBR-4405 –44-pin to 40-pin Adapter (one for each 3.5” drive)
Note: Non-RoHS-compliant versions of these cables are no longer available for
purchase. Non-RoHS cable part numbers begin with the prefix CBL and have the
same base numbers as their RoHS counterparts. If you own non-RoHS cables, they
can be used with the EPM-32p or EPM-32t in non-RoHS applications only.
The VL-ENCL-5b enclosure provides a portable benchtop platform for system development. See
the VL-ENCL-5 product page for information.
Basic Setup
The following steps outline the procedure for setting up a typical development system. The
EPM-32 should be handled at an ESD workstation or while wearing a grounded antistatic wrist
strap.
Before you begin, unpack the EPM-32 and accessories. Verify that you received all the items you
ordered. Inspect the system visually for any damaged that may have occurred in shipping.
Contact [email protected] immediately if any items are damaged or missing.
Gather all the peripheral devices you plan to attach to the EPM-32 and their interface and power
cables.
It is recommended that you attach standoffs to the board to stabilize the board and make it easier
to work with.
Figure 2 shows a typical start-up configuration (using RoHS compatible cables).

4. Review Configuration
Before you power up the system, double check all the connections. Make sure all cables
are oriented correctly and that adequate power will be supplied to the EPM-32 and
peripheral devices.
5. Power On
Turn on the ATX power supply and the video monitor. If the system is correctly
configured, a video signal should be present.
6. Change CMOS Setup Settings
Enter CMOS Setup by pressing Delete during the early boot cycle.
Select Basic Configuration and set or verify the following settings:
DRIVE ASSIGNMENT ORDER | Drive C: Ide 0/Pri Master
ATA DRV ASSIGNMENT | Ide 0: 3 = AUTOCONFIG, LBA
ATA DRV ASSIGNMENT | Ide 1: 5 = IDE CDROM
BOOT ORDER | Boot 1st: CDROM
BOOT ORDER | Boot 2nd: Drive C:
Before saving the CMOS Setup settings, insert the Windows (or other OS) installation
disk in the CD-ROM drive so it will be accessed when the system reboots.
Press ESC and select the option to save the new parameters to CMOS RAM. The system
will reboot.
7. Install Operating System
Install the operating system according to the instructions provided by the OS
manufacturer. (See Operating System Installation.)
Note:If you intend to operate the EPM-32 under Windows XP or Windows XP
Embedded, be sure to use Service Pack 2 (SP2) for the latest hardware support features.
CMOS Setup
See VersaLogic KnowledgeBase article VT1472 –EPM-32 CMOS Setup Reference for
complete information on the CMOS configuration for the EMP-32.
Operating System Installation
The standard PC architecture used on the EPM-32 makes the installation and use of most of the
standard x86 processor-based operating systems very simple. The operating systems listed on the
VersaLogic OS Compatibility Chart use the standard installation procedures provided by the
maker of the OS. Special optimized hardware drivers for a particular operating system, or a link
to the drivers, are available at the EPM-32 Product Support web page at
http://www.VersaLogic.com/private/cheetahsupport.asp.

HARDWARE ASSEMBLY
The EPM-32 consists of two boards that are mounted together with four 5mm x 15mm M3
threaded hex male/female standoffs (p/n VL-HDW-101) using the corner mounting holes. These
standoffs are secured to the top circuit board using four pan head screws.
Caution: Extreme care must be taken not to damage components near the corner mounting
holes when tightening standoffs with nut driver tools.
Additional PC/104-Plus or PC/104 cards can be attached to the bottom of the EPM-32 board set
and secured with standoffs or 5mm nuts.
PC/104-Plus expansion modules can be secured directly to the underside of the EPM-32.
PC/104 expansion modules can be secured to the underside of the EPM-32; however, the 40-pin
and 64-pin ISA pass-through connectors may need to be extended, and longer standoffs might
need to be used to provide adequate clearance between the PCI connector and the components on
the top side of the PC/104 expansion module.
The entire assembly can sit on a table top or it can be secured to a base plate. When bolting the
unit down, make sure to secure all four standoffs to the mounting surface to prevent circuit board
flexing. Refer to the drawing on page 10 for dimensional details.
An extractor tool is available (part number VL-HDW-201) to separate the modules from the
stack.

CONNECTING THE NORTH BRIDGE AND SOUTH BRIDGE BOARDS
Warning! When connecting the north bridge and south bridge boards of the EPM-32, you
must be sure that sockets JN5 and JN6 on the north bridge board mate perfectly
with headers JS2 and JS3 of the south bridge board. Failure to connect the boards
properly could cause serious damage and void the warranty.
To connect the north and south bridge boards of the EPM-32, follow this procedure:
1. Attach all four 5mm x 15mm standoffs to the top of the south bridge board using the
provided screws.
2. Hold the boards so that sockets JN5 and JN6 are aligned with headers JS2 and JS3, and
the standoffs are aligned with the holes of the north bridge board.
3. Lower the north bridge board over the standoffs while visually aligning sockets JN5 and
JN6 with headers JS2 and JS3. Make sure the pins match the sockets perfectly before
applying the pressure required to seat the connectors.
4. Secure standoffs to the north bridge board with the provided hex nuts.
