RoHS-Compliance



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 EBX-18.

The EBX-18 is RoHS-compliant.

BOUT ROHS

A

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 poly-brominated 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.

Cautions

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:

LITHIUM BATTERY

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.

OUNTING SUPPORT

M

The single board computer must be supported at all eight mounting points to prevent excessive
flexing when expansion modules are attached and removed. Flex damage caused by excessive
force on an improperly mounted circuit board is not covered under the product warranty. See
page 10 for more details.

EBX-18 Hardware Reference Manual 4

Introduction

EARTH GROUND REQUIREMENT

All mounting standoffs should be connected to earth ground (chassis ground). This provides
proper grounding for EMI purposes. Figure 2 shows the locations of the board’s mounting holes.
All eight mounting holes identified in Figure 2 must be connected to earth ground.

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

each system. This restriction does not apply if you are producing multiple identical systems.



Integrator’s Note:

The Anaconda board has been tested extensively with Windows 7 and seems to operate reliably

required by the OS.

Refer to the BIOS Reference Manual (available on the EBX-18 Product Support Web Page) for
information on accessing and configuring settings in the BIOS Setup program. All BIOS menus,
submenus, and configuration options are described in the BIOS Reference Manual.

Operating System Installation

The standard PC architecture used on the EBX-18 makes the installation and use of most of the
standard x86 processor-based operating systems relatively 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 EBX-18 Product Support Web Page.

Note:

EBX-18. 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 EBX-18 and expected to boot. Even
when porting an OS image from one revision of the EBX-18 to another, performance might fail
or be impaired. For the best results, perform a fresh installation of the operating system on

Configuration and Setup

ACPI VERSION SETTING

The ACPI version will need to be configured in the BIOS Setup program as follows:

 For Windows 7, set the ACPI version to V3.0. (Windows 7 requires version 2.0 or later.)
 For Windows XP, set the ACPI version to V1.0 (Windows XP may function with version 2.0

but has not been fully tested.)

with the ACPI version set to V3.0. Other operating systems may have unique requirements for
setting the supported ACPI version. ACPI can be disabled in the BIOS Setup program if it is not

HARDWARE ASSEMBLY

The EBX-18 mounts on four hardware standoffs using the corner mounting holes (A). These
standoffs are secured to the underside of the circuit board using pan head screws.

Four additional standoffs (B) must be used under the circuit board to prevent excessive flexing
when expansion modules are mated and separated. These are secured with four male-female
standoffs (C), threaded from the top side, which also serve as mounting struts for the PC/104
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 eight standoffs (A and B) to the mounting surface to prevent
circuit board flexing.

An extractor tool is available (part number VL-HDW-201) to separate the PC/104 modules from
the stack.

Note: Standoffs and screws are available as part number VL-HDW-101.

Battery is disconnected

(not discharging)

Nominal battery voltage is 3.0V. If the voltage drops below 2.7V, contact the factory for a
replacement. The life expectancy under normal use is approximately five years.

CAUTION:

place the board on a conductive surface such as met al, black conductive foam
or the outside surface of a m etalized ESD protective pouch. The Lithium
battery may explode if mistreated. Do not recharge, disassemble, or dispose of

BATTERY SAVER JUMPER

The EBX-18 includes a “Battery Saver” jumper at location V13. This jumper keeps the Lithium
battery from discharging (keeping it disconnected) before the EBX-18 board is in the customer’s
hands and ready to be used. The default configuration of the jumper is a no-connect position
(placed only on pin 1). Figure 8 shows the location of the V13 Battery Saver Jumper.

System Features

OPERATING THE BOARD WITHOUT A BATTERY

The EBX-18 enables you to operate the board without a battery for applications when no battery
is required. Note that using this setting will delay the board boot after power on for
approximately 5 seconds. This is an application requirement to give the RTC crystal time to start
up.

V14 Jumper Position Condition

Pin 2-3 (default) Battery is installed and will be used

Pin 1-2 Battery has been removed

Figure 9. Location of the V14 No Battery Mode Jumper

To operate the board without the Lithium battery, perform the following steps:

1. Power down the EBX-18.

2. Remove the battery connection to the SoC RTC well. This is done by removing the

battery from its socket, or by removing the V13 jumper leaving pins 1 and 2 unconnected
if you want to keep the battery with the product. (You can store the V13 jumper in its
default position connected only to pin 1.)

3. Set the V14 jumper to pins 1-2. (Always make sure the battery is disconnected when this

jumper setting is used or it will drain the battery and delay booting of the board.)

4. Power up the EBX-18. The board takes approximately five seconds to begin the boot

sequence after the power switch is turned on when the battery is not in use. This delay is
necessary for the RTC crystal operation to stabilize before the board reset is released.

BOOTING FROM A PCIE MINICARD

The MSATA_DETECT (J19 pin 43) signal is non-functional as an option for the PCIe Minicard
mux selection. This signal has a pull-down internal to the FPGA to prevent it from floating high
(which enables it). The FPGA default is to use J19 pin 51 as the mux enable signal
(PRES_DISABLE2#) which works with all of our Minicards.

The result of this condition is that certain combinations of bootable devices may not yield
expected results. Table 14 is a matrix of acceptable boot device configurations.

Serial Ports

Jumper

Position

The EBX-18 includes four on-board 16550-based serial channels located at standard PC I/O
addresses. Each COM port can be independently enabled or disabled in BIOS Setup.

 All four COM ports by default are set to RS-232 mode
 COM1 and COM2 are RS-232 (115.2K baud) serial ports. There are no configuration

jumpers for COM1 and COM2 because they only operate in RS-232 mode. IRQ lines are
chosen in the BIOS Setup program.

 COM3 and COM4 can be operated in RS-232 or RS-422/485 mode. IRQ lines are chosen in

the BIOS Setup program.

Additional non-standard baud rates are also available through the BIOS Setup program.

Interfaces and Connectors

COM3/COM4

HARDWARE CONFIGURATION

Jumper block V1[3-4] enables the RS-422/485 termination resistor for COM3. Jumper V1[7-8]
enables the RS-422/485 termination resistor for COM4. The termination resistor should be
enabled for an RS-422 endpoint station; it should be disabled for RS-232 and RS-485 non­endpoint receivers.

COM3/COM4 SOFTWARE CONFIGURATION

By default, COM3 and COM4 are configured for RS-232 operation. Two registers in the
Vortex86DX2 (0x9A and 0x7A) need to be programmed for COM3 and/or COM4 to operate in
RS-422 or RS-485 mode. Table 17 and Table 18 provide bit-level descriptions of these registers.

To configure COM3 and COM4 for RS-422/485 Mode

1. Write 0xFF to I/O register 0x9A (sets GPIO-P2[7:0] to outputs)

2. Write 0x0E to I/O register 0x7A (disables RS-232 mode and enables transceivers)

SERIAL PORT ASSIGNMENT

The EBX-18 only supports the use of the Vortex86DX2 Serial Ports 1, 2, 4, and 9, so all other
serial ports are disabled and not available in the BIOS Setup Utility. Table 19 lists the
recommended settings (tested with Windows 7) for the Vortex86DX2 serial ports, along with
correlation to the board’s J4 I/O connector (shown in the rightmost column).

USB

Interfaces and Connectors

The USB interface on the EBX-18 is OHCI (Open Host Controller Interface) and EHCI
(Enhanced Host Controller Interface) compatible, which provides a common industry
software/hardware interface. The board has five USB ports:

 Three on-board ports at locations J20, J21, and J22 using standard USB Series A sockets

(see Figure 5 on page 12)

 Two hubbed ports routed to the J10 I/O connector. Table 11 page 25 lists the USB port

signals routed to the J10 connector.

The USB interfaces at connector J10 are accessible using a CBR-4004B paddleboard or by using
a custom cable. Figure 23 on page 54 shows the connection points for accessing the USB ports
routed from J10 to a CBR-4004B paddleboard.

All five USB ports use IEC 61000-4-2-rated TVS components to help protect against ESD
damage.

BIOS

CONFIGURATION

The USB controller can be enabled or disabled in the BIOS Setup program.

microSD Socket

The EBX-18 includes a microSD socket. The VL-F41 series of microSD cards provide solid­state storage of 2 GB, 4 GB, or 8 GB. The microSD socket accommodates cards with up to 32
GB of storage capacity. No drivers are needed, as the device interface is abstracted as a standard
parallel IDE drive on the master IDE channel. Note the following when using a microSD card
with the EBX-18:

 The microSD card interface is not hot-pluggable. A microSD card will not be recognized as

part of the system if it is not plugged in before power is applied to the board or before a
push-button reset is applied. This is not a limitation of the EBX-18 board; it is a limitation
of the DX2 chip.

 When a microSD card is inserted at power-up, the default boot setting is to boot from it (it is

primary), so if you don’t press <F11> right after applying power to the board, you will not be
able to select an alternate boot option; the board will “stall” for the lack of an operating
system (OS) if there isn’t one present on the microSD card.

 The boot order can be changed in the BIOS Setup program.
 If you remove the microSD card at any time and allow the board to boot without the card

installed, the boot order setting will be cleared and you will have to set it up again the next
time you use a microSD card.

 If you remove the microSD card while the board is powered on and the OS attempts to access

a file on the “drive” (that is, the microSD card) the results are unpredictable. The best case
scenario is that the drive drops out (as it would in Windows Explorer when running
Windows 7 from a SATA drive and using the microSD as an additional hard drive).
However, if Windows does not try to access the microSD card while you have it out and you
put it back in (again, in Windows 7 at least) the system does not appear to have noticed it
was ever removed.

EBX-18 Hardware Reference manual 33

Programmable LED

Utility I/O connector J4 includes an output signal for attaching a software controlled LED.
Connect the cathode of the LED to J4, pin 48; connect the anode to +5V. An on-board resistor
limits the current to 15 mA when the circuit is turned on. A programmable LED is provided on
the CBR-5009B paddleboard. See Figure 21 on page 49 for the location of the Programmable
LED on the CBR-5009B paddleboard.

For instructions on how to switch the PLED on and off, refer to the EBX-18 Programmer’s
Reference Manual (available on the EBX-18 Product Support Web Page).

External Speaker

A miniature 8 Ω speaker can be connected between J4, pin 50 (SPKO*) and J4, pin 49
(MKPWR). A speaker is provided on the CBR-5009B paddleboard. See Figure 21 on page 49
for the location of the speaker on the CBR-5009B paddleboard.

Push-Button Reset

Connector J4 includes an input for a push-button reset switch. Shorting J4, pin 37 to ground
causes the EBX-18 to reboot.

Interfaces and Connectors

This connector uses IEC 61000-4-2-rated TVS components to help protect against ESD damage.
A reset button is provided on the CBR-5009B paddleboard. See Figure 21 on page 49 for the

location of the reset button on the CBR-5009B paddleboard.

Video Interface

An on-board video controller integrated into the Vortex86DX2 SoC provides high performance
video output for the EBX-18.

ONFIGURATION

C

The EBX-18 uses shared memory architecture. This allows the video controller to use variable
amounts of system DRAM — 8 MB, 16 MB (default), 32 MB, or 64 MB — for video RAM.
The amount of RAM used for video is set with a BIOS Setup program option.

The EBX-18 supports two types of video output: SVGA and LVDS flat panel display. A BIOS
Setup program sub-menu (Boot Display Device) selects which output is enabled through POST.
The operating system will then take over based on the Graphic Utility CRT or LCD selection. If
the Boot Display Device selected provides incorrect timing information for an attached LCD
panel and the Graphics Utility is set to LCD, you may not see video on the output.

Refer to Table 24 on page 37 for a list of BIOS settings for boot display devices and their
corresponding resolutions.

DMA Controller

The DMA circuitry incorporates the functionality of two 82C37 DMA controllers with seven
independently programmable channels. The Master DMA Controller (DMA-1) corresponds to
DMA Channels 0-3 that are hardwired to 8-bit count-by-byte transfers and the Slave DMA
Controller (DMA-2) corresponds to Channels 5-7 that are hardwired to 16-bit count-by-word
“address shifted” transfers. DMA Channel 4 is used to cascade the two controllers and will
default to cascade mode as it cannot be used for any other purpose. In addition to accepting
requests from DMA slaves, the DMA controller also responds to requests that are initiated by
software.

The Vortex86DX2 provides the timing control and data size translation for the DMA transfer
between memory (ISA or DRAM) and the ISA Bus I/O. Also, the DX2 is ISA-compatible with
24-bit addressing. For information on programming the DMA controller, contact

[e-mail].

Interfaces and Connectors

Watchdog Timers

The watchdog timers use the RTC frequency (32.768 kHz) for a 24-bit counter, providing a time
range from 30.5 μs to 512 seconds with a resolution of 30.5 μs. When the timer is enabled and
its count reaches the programmed value, a system reset, NMI, or IRQ may occur as selected
using the Watchdog Configuration sub-menu in the BIOS Setup program.

Industrial I/O Functions and SPI Interface

The EBX-18 employs a set of I/O registers for controlling on-board analog input, digital I/O, and
external serial peripheral interface (SPI) devices. These functions share control and data
registers located at I/O addresses whose range depends on programmed FPGA PCI BAR added to
offsets 0x00-0xFF. Refer to the EBX-18 Programmer’s Reference Manual (available on the

EBX-18 Product Support Web Page) for additional information.

The EBX-18 employs a Linear Tech LTC1857 A/D device. This device operates off a single 5V
supply to provide eight 12-bit analog inputs. The LTC1857 provides eight single-ended input
channels; or alternatively each even and odd analog channel “pair” (for example inputs 1 and 2
or 5 and 6) can be combined as differential inputs or you can also have combinations of both
single-ended and differential channels. The converter has a 100 kilo-samples-per-second (ksps)
sampling rate, with a 4 μs acquisition time and per-channel input ranges of 0 to 5V, ±5V, 0 to
+10V and ±10V.

Communications with the A/D converter are handled by the FPGA, which uses the SPX slave
selection signal for SPI device 5 to enable the A/D read strobe for the SPI interface. Refer to the
EBX-18 Programmer’s Reference Manual (available on the EBX-18 Product Support Web Page)

The EBX-18 includes a 32-channel digital I/O interface. The digital lines are grouped as four 8­bit bi-directional ports. Data direction and output driver type are configurable by software.

Input data can be inverted through register settings. Any I/O pin(s) can generate an interrupt on
change of state. All I/O pins use 3.3V signaling. As outputs, the I/O pins can source or sink an
absolute maximum of 25 mA each.

CAUTION:

EBX-18 digital I/O ports are accessed through the FPGA SPI interface.

DIGITAL I/O PORT CONFIGURATION

For information on digital I/O port configuration refer to the EBX-18 Programmer’s Reference
Manual, (available on the EBX-18 Product Support Web Page).

INTERRUPT GENERATION

The EBX-18 digital I/O can be configured to issue hardware interrupts on the transition (high to
low or low to high) of any digital I/O pin. Note that this interrupt is shared among all SPI
devices on-board and externally connected to the EBX-18. Digital I/O port interrupt
configuration is achieved through I/O port register settings. Refer to the Microchip MCP23S17

datasheet for more information.

The on-board digital I/O chips must be configured for open-drain and mirrored interrupts in order
for any SPI device to use hardware interrupts.

VERSALOGIC SPX EXPANSION MODULES

VersaLogic offers several SPX modules that provide a variety of standard functions, such as
analog input, digital I/O, CANbus controller, and others. These are small boards (1.2” x 3.775”)
that can mount on the PC/104 and PC/104-Plus stack, using standard PC/104 stand-offs, or up to
two feet away from the base board. For more information, contact VersaLogic at

[e-mail].

The Vortex86DX2 ISA bus interface is an 8/16-bit ISA device with zero-wait-state and is
available through the Vortex86DX2 SoC’s internal ISA-to-PCI bridge. The maximum ISA clock
frequency is 33 MHz. The AT clock is programmable. The SoC generates refresh signals to the
ISA interface during the DRAM refresh cycle. (This means the ISA Refresh signal would be
modified with the DRAM refresh rate change from ~15 μs to ~3.9 μs).

different IRQ for COM1 to avoid resource conflicts.

Seven IRQs have been shown to work with the ISA bus expansion cards. As listed in Table 32,
they are IRQ3, IRQ4, IRQ5, IRQ6, IRQ7, IRQ10, and IRQ11. There are conflicts with all other
IRQ assignments per the Vortex86DX2 resources, and by default IRQ3, IRQ4, IRQ10 and IRQ11
are assigned to the four COM Ports. If the ISA expansion card requires more than three IRQs,
you may have to disable the COM Port using the desired IRQ, taking care to ensure each of the
required IRQs are reserved from PCI use in the BIOS Setup program (PCIPnP settings). IRQ
selection often requires checking to make sure the system does not have resource conflicts.

The EBX-18 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 resources listed in Table 32.

Notes:

1. The I/O ranges allocated to COM ports 1-4 are available to ISA only when the on-board COM ports are
disabled in the BIOS Set up program.

2. Each of these IRQs must be reserved from the PCI PnP use in the BIOS S et up program before they can
potentially be used on the ISA bus. Because ISA IRQ sharing is not supported, m ake sure that any IRQ
channel used for an ISA device i s not used elsewhere. For example, if IS A IRQ4 is enabled, you must us e a

LUS PCI EXPANSION INTERFACE

The EBX-18 supports a full PCI interface for all four slots. The Vortex86DX2 SoC does not
support a PCI interface directly so an XIO2001 PCIe-to-PCI bridge device is used.

The only features not supported are:

 66 MHz mode (the EBX-18 board only supports 33 MHz)
 PSON# power control
 +5V_SB standby power

Note that the PCI connector VI/O power pins are connected to the V3P3 power supply on-board
which turns on with the PCI Bridge device, whereas the PCI connector +3.3V pins are tied to the
V3P3_ATX rail direct from the input power connector.
