Warranty Repair All parts and labor charges are covered, including return shipping
charges for UPS Ground delivery to United States addresses.
Non-warranty Repair All non-warranty repairs are subject to diagnosis and labor charges,
parts charges and return shipping fees. Specify the shipping method
you prefer and provide a purchase order number for invoicing the
repair.
Note: Mark the RMA number clearly on the outside of the box before returning. Failure to do so can delay
the processing of your return.
RoHS Compliance
The EBX-38 is 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 poly-brominated biphenyls (PBB) and poly-
brominated 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
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 EBX-38.
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.

EBX-38 Hardware Reference Manual v
MOUNTING SUPPORT
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 5 for more details.
EARTH GROUND REQUIREMENT
All mounting standoffs should be connected to earth ground (chassis ground). This provides
proper grounding for EMI purposes. The figure below shows the locations of the board’s
mounting holes. All mounting holes identified in below must be connected to earth ground.

Thermal Considerations
The operating temperature for the EBX-38 is -40 °C to +85 °C, de-rated -1.1 °C per 305m (1,000
ft.) above 2,300m (7,500 ft.). All Viper models include a rigid-mount heat plate thermal solution.
Refer to the Chapter 13, beginning on page 61 for information on additional thermal solutions.

Dimensions and Mounting
The EBX-38 complies with the PC/104 standard which provides for specific mounting holes and
PC/104-Plus stack locations as shown below.
Figure 4. EBX-38 Dimensions and Mounting Holes
(Not to scale. All dimensions in inches.)
CAUTION:
The EBX-38 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.

Introduction
EBX-38 Hardware Reference Manual 6
HARDWARE ASSEMBLY
The EBX-38 mounts on four hardware standoffs using the corner mounting holes, and four more
surrounding the PC/104-Plus area. These standoffs are secured to the underside of the circuit
board using pan head screws for the corner mounts, and four more standoffs for the topside in
PC/104-Plus area.
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 standoffs to the mounting surface to prevent circuit board flexing.
An extractor tool is available (part number VL-HDW-203) to separate the PC/104 modules from
the stack.

Configuration and Setup
Initial Configuration
The following components are recommended for a typical development system.
VL-EBX-38 single board computer
VL-MM9-xxEBN DDR3L SO-DIMM module (see System RAM)
ATX power supply with motherboard and disk drive connectors
VGA video monitor
USB Keyboard
USB Mouse
SATA hard drive
The following VersaLogic cables and accessories are recommended.
EBX-38 cable kit (CKR-VIPER)
12” VGA Video adapter cable (CBR-1204) – 18” cable is CBR-1206
User I/O cable (CBR-4005) and accompanying paddleboard (CBR-4005B)
VL-CBR-0702 – SATA data cable
VL-CBR-2022 – ATX to 5V power adapter (or VL-CBR-2034 6” 20-pin (F) ATX to 24-pin
(M) ATX adapter cable (use with PS-ATX12-300A))
(Cat5e cables)
Note: Only one of the listed power adapters can be used.
You will also need a Windows* (or other OS) installation CD/DVD and corresponding drive.
Basic Setup
The following steps outline the procedure for setting up a typical development system. The EBX-38
should be handled at an ESD workstation or while wearing a grounded antistatic wrist strap.
Before you begin, unpack the EBX-38 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 Viper as well as their interface and
power cables.
It is recommended that you attach standoffs to the board (see Hardware Assembly)to stabilize the
board and make it easier to work with.

Configuration and Setup
EBX-38 Hardware Reference Manual 8
1. Install Memory
Insert the DDR3L DRAM module into the SO-DIMM socket on the top side of the board
and latch it into place. If you have an EBP or ECP SKU of the EBX-38, you may install a
matching DDR3L DRAM module into the SO-DIMM socket on the bottom side of the
board as well.
2. Attach Cables and Peripherals
Plug the VGA cable VL-CBR-1204 into socket J5. Attach the cable to a VGA display.
(Alternatively, you can attach a DisplayPort-enabled display to the Mini DisplayPort
connectors at J3 or J30, or remove jumper V9 and connect J33 for LVDS panel (see
jumper settings for LVDS resolutions).)
Plug the VL-CBR-4005B paddleboard into socket J4.
Plug a USB CD-ROM drive, USB keyboard, and USB mouse into any of the USB
connectors of the CBR-4005B paddleboard.
Plug the SATA data cable VL-CBR-0702 into socket J2 or J36. Attach a hard drive to the
connector on the cable.
Attach the SATA power adapter cable VL-CBR-0401 to the ATX power supply and
SATA drive.
Optionally, attach a LAN cable to either of the Ethernet connectors at J1 or J7 on the
EBX-38.
3. Attach Power
Plug the power adapter cable CBR-2022 into connector J20. Attach the motherboard
connector of the ATX power supply to the adapter.
Verify that the V10 jumper is selecting 5V (installed on pins 1 and 2).
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 VL-EBX-38 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. Select a Boot Drive
During startup, press <CTRL> <B> to display the boot menu. Insert the OS installation
CD in the CD-ROM drive and select to boot from the CD-ROM drive.
7. Install Operating System
Install the operating system according to the instructions provided by the operating
system manufacturer. (See Operating System Installation on page 14.)
