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.

to the drivers, are available at the EPM-14 Product Support web page at

http://www.versalogic.com/private/cougarsupport.asp

use the standard installation procedures provided by the

Configuration and Setup

.

Note An operating system installed on a different type of computer is not guaranteed to

work on the EPM-14. This is referred to as a “foreign” installation. A hard disk that
was used to boot a different computer cannot necessarily be moved to the EPM-14
and expected to boot. Even when porting an OS image from one revision of the
EPM-14 to another, performance might fail or be impaired. For the best results,
perform a fresh installation of the OS on each system. This restriction does not
apply if you are producing multiple identical systems.

HARDWARE ASSEMBLY

The EPM-14 uses PC/104 and PC/104-Plus connectors so that expansion modules can be added

to the top of the stack. PC/104 (ISA) modules must not be positioned between the EPM-14 and

any PC/104-Plus (PCI) modules on the stack.

The entire assembly can sit on a table top or 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. Standoffs are secured to the top circuit board using four pan head screws. Standoffs and
screws are available as part number VL-HDW-101.

An extractor tool is available (part number VL-HDW-201) to separate the PC/104 modules from
the stack. Use caution when using the extractor tool not to damage any board components.

Power Supply

POWER CONNECTORS

Main power is applied to the EPM-14 through a 10-pin polarized connector, with mating
connector Berg 69176-010 (Housing) + Berg 47715-000 (Pins). See the table below for the
connector pinout.

Warning! To prevent severe and possibly irreparable damage to the system, it is critical that

the power connectors are wired correctly. Make sure to use both +5VDC pins and
all ground pins to prevent excess voltage drop. Some manufacturers include a pin-1
indicator on the crimp housing that corresponds to pin-10 of the pinout shown in
Figure 13.

System Features

Note: The +3.3VDC, +12VDC and -12VDC inputs are required only for expansion

modules that require these voltages.

OWER REQUIREMENTS

P

The EPM-14 requires only +5 volts (±5%) for proper operation. The voltage required for the
RS-232 ports are generated with a DC/DC converter. Low-voltage supply circuits provide power
to the CPU and other on-board devices.

The exact power requirement of the EPM-14 depends on several factors, including peripheral
connections, type and number of expansion modules, and attached devices. For example, driving
long RS-232 lines at high speed can increase power demand.

ITHIUM BATTERY

L

Warning! 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 used batteries promptly.

Normal battery voltage should be at least 3.0V. If the voltage drops below 3.0V, contact the
factory for a replacement (part number HB3/0-1). The life expectancy under normal use is
approximately 10 years.

CPU

The Geode LX 800 microcontroller has a 32-bit, low-voltage AMD x86 microprocessor at its
core. The maximum clock rate is 500 MHz actual, with 800 MHz (Celeron equivalent)
performance. The LX 800 features 64 kb of L1 cache, 128 kb of L2 cache, DDR SDRAM
support, and an integrated display controller. The CPU has a typical power consumption of 1.6W.

System RAM

The EPM-14 has one soldered-on DDR memory module with the following characteristics:

 Size 256 MB
 Voltage 2.6V
 Type PC2700 compatible (DDR 333 MHz)

Note CMOS settings default to DDR 333 MHz. Settings to DDR 400 MHz are available,

but VersaLogic only guarantees operation at the default settings.

EPM-14 Reference Manual 22

CMOS RAM

CLEARING CMOS RAM

A jumper may be installed into V1[2-3] to erase the contents of the CMOS RAM and the real­time clock. When clearing CMOS RAM: 1) Power off the EPM-14. 2) Remove the jumper from
V1[1-2], install it on V1[2-3] and leave it for four seconds. 3) Move the jumper to back to
V1[1-2]. 4) Power on the EPM-14.

CMOS Setup Defaults

The EPM-14 permits users to save custom CMOS defaults, which override factory defaults. This
allows the system to boot with user-defined settings if CMOS RAM is cleared or corrupted. The
factory defaults remain available for restoration in the main BIOS Setup screen. All CMOS Setup
defaults can be customized, except the time and date. The CMOS Setup defaults can be updated
with the Flash BIOS Update (FBU) Utility, available from the General BIOS Information

Warning! If the CMOS Setup default settings make the system unbootable and prevent the user

from entering CMOS Setup, the EPM-14 needs to be serviced by the factory.

System Features

page.

EFAULT CMOS RAM SETUP VALUES

D

After the CMOS RAM is cleared, the system will load default CMOS RAM parameters the next
time the board is powered on. The default CMOS RAM setup values will be used in order to boot
the system whenever the main CMOS RAM values are blank, or when the system battery is dead
or has been removed from the board.

AVING CMOS SETUP PARAMETERS AS CUSTOM DEFAULTS

S

To save CMOS Setup parameters to custom defaults, you will need a DOS bootable floppy with
the FBU utility on it.

1. Boot the EPM-14 and enter CMOS Setup by pressing Delete during the early boot cycle.

2. Change the CMOS parameters as desired and configure the floppy drive as the first boot

device:

DRIVE ASSIGNMENT ORDER | Drive A: USB Floppy

Basic CMOS Configuration | BOOT ORDER | Boot 1st: Drive A:

3. Save the settings and exit CMOS Setup.

4. Reboot the system from the DOS boot floppy.

5. Run FBU and select Save CMOS contents. A file named CMOS.BIN is created and

saved to the floppy.

6. Select the FBU option Load Custom CMOS defaults. A directory of the floppy is

displayed.

7. Select the CMOS.BIN file and press the P key to program the new CMOS defaults.

8. Reboot the system from the hard disk. The custom CMOS parameters are now saved as

defaults.

EPM-14 Reference Manual 23

Real Time Clock

The EPM-14 features a battery-backed 146818-compatible real-time clock/calendar chip. Under
normal battery conditions, the clock maintains accurate timekeeping functions when the board is
powered off.

ETTING THE CLOCK

S

The CMOS Setup utility (accessed by pressing the Delete key during a system boot) can be used
to set the time/date of the real-time clock.

Serial Ports

The EPM-14 features three on-board 16550-based serial channels located at standard PC I/O
addresses. COM1 and COM2 are RS-232 (115.2K baud) serial ports. IRQ lines are chosen in
CMOS Setup. COM3 operates in RS-422 or RS-485 mode. IRQ lines are chosen in the CMOS
Setup. Each COM port can be independently enabled or disabled in CMOS Setup.

For information on setting the COM ports to high-speed baud rates, see the AMD LX 800 Data

Book (COM1 and COM2) or the AMD CS5536 Companion Device Data Book (COM3).

COM

PORT CONFIGURATION

There are no configuration jumpers for COM1 and COM2 since they only operate in RS-232
mode. Jumper V3 is used to enable the RS-422/485 termination resistor for COM3. The
termination resistor should be enabled for RS-422/485 endpoint station. It should be disabled for
the RS-485 intermediate station.

CONSOLE REDIRECTION

The EPM-14 can be operated without using the on-board video output by redirecting the console
to COM1. CMOS Setup and some operating systems such as DOS can use this console for user
interaction.

In the Features Configuration screen, there is an option to control console redirection. This option
can be set to Auto or Redirect. When set to Auto, the console will not be redirected to COM1
unless a signal is detected from the terminal by pressing CRTL-C or ENTER.. When set to
Redirect, the console will be directed to COM1.

Notes on console redirection:

 When console redirection is enabled, you can access CMOS Setup by typing Ctrl-C.
 The decision to redirect the console is made early in BIOS execution and cannot be

changed later.

 The redirected console uses 115200 baud, 8 data bits, 1 stop bit, no parity, and no flow

control.

 The default console redirection setting is Auto. The default can be reloaded without

entering BIOS setup by discharging CMOS contents.

Null Modem:

Ethernet Interface

The EPM-14 features two Intel 82551ER Fast Ethernet controllers on-board. While these
controllers are not NE2000-compatible, they are widely supported. Drivers are readily available
to support a variety of operating systems. See VersaLogic website for latest OS support.

CONFIGURATION

BIOS

Ethernet interface 0 (J3) uses PCI interrupt INTA# and Ethernet interface 1 (J2) uses PCI
interrupt INTB#. CMOS Setup is used to select the IRQ line routed to each PCI interrupt line.

TATUS LED

S

Each Ethernet controller has a two-colored LED located next to its RJ-45 connector to provide an
indication of the Ethernet status as follows:

Green LED (Link):

 ON Active Ethernet cable plugged in
 OFF Active cable not plugged in

or cable not plugged into active hub

Interfaces and Connectors

Yellow LED (Activity):

 ON Activity detected on cable
 OFF No Activity detected on cable

THERNET CONNECTOR

E

Board-mounted RJ-45 connectors are provided to make connections with Category 5 Ethernet
cables. The 82551ER Ethernet controller auto-detects 10BaseT/100Base-TX connectors.

These connectors use IEC 61000-4-2-rated TVS components to help protect against ESD damage.

CPU Temperature Monitor

A thermometer circuit constantly monitors the die temperature of the CPU. This circuit can be
used to detect over-temperature conditions which can result from fan or heat sink failure or
excessive ambient temperatures.

The system can be configured to generate an interrupt when the temperature exceeds the BIOS
programmed threshold. Contact the factory for information on reading and writing to the
thermometer circuits.

PC/104 Expansion Bus

EPM-14 has limited support of the PC/104 bus. Most PC/104 cards will work, but be sure to
check the requirements of your PC/104 card against the list below.

Interfaces and Connectors

PC/104

I/O SUPPORT

The ISA I/O ranges listed below are supported. The I/O ranges allocated to COM ports 1-3 are
available to ISA when the on-board COM port function is disabled in CMOS Setup.

• 100h – 1CFh

1DFh – 1EFh
200h – 3AFh
3E0h – 3F5h
3F7h – 47Fh
490h – 4CFh
4D2h – 777h
77Ch – AFFh

• When on-board COM ports are enabled in CMOS Setup: COM1 (0x3F8-0x3FF), COM2

(0x2F8-0x2FF), COM3 (0x3E8-0x3EF).

PC/104

MEMORY SUPPORT

Memory ranges supported:

• C8000h-DBFFFh

SUPPORT

IRQ

The following IRQs are available on the PC/104 bus:

• IRQ 3, IRQ 4, IRQ 5, IRQ 6, IRQ 7, IRQ 9, and IRQ 10

Each of the seven IRQs must be enabled in CMOS Setup before they can be used on the ISA bus.
Because ISA IRQ sharing is not supported, make sure that any IRQ channel used for an ISA
device is not used elsewhere. For example, if ISA IRQ 4 is enabled, you must use a different IRQ
for COM1. There are three mutually exclusive IRQ domains: PCI, ISA, and on-board COM ports.

SUPPORT

DMA

The current revision of the board does not support PC/104 DMA.

EPM-14 Reference Manual 36

Memory Map

The lower 1 MB memory map of the EPM-14 is arranged as shown in the following table.

Various blocks of memory space between C0000h and FFFFFh can be shadowed. CMOS Setup is
used to enable or disable this feature.

I/O Map

The following table lists the common I/O devices in the EPM-14 I/O map. User I/O devices
should be added using care to avoid the devices already in the map as shown in the following
table.

Interrupt Configuration

The EPM-14 has the standard complement of PC type interrupts. Four non-shared interrupts are
routed to the PC/104 bus, and up to four IRQ lines can be allocated as needed to PCI devices. The
following tables show the default and allowed interrupt settings. There are no interrupt
configuration jumpers. All configuration is handled through CMOS Setup. If your design needs
to use interrupt lines on the PC/104 bus, IRQ5 and IRQ10 are recommended. (IRQ3 and IRQ4 are
normally used by COM ports on the main board.)
