ETX-CN700 Product Summary
Page | 6
Introduction
The Blue Chip Technology ETX CN700 complies with the embedded ETX standard Version 3.02 set of Bus
interface signals and peripheral IO devices interfaces on a single card. The concept of ETX is to provide the user
with a standard connector interface with fixed connector locations and predefined IO functions. This allows the
user to concentrate their design efforts on the supporting base board for the target application. This modular
approach provides a cost effective means of system upgrade and allows the user to easily validate a number of
CPU board price/power/performance options.
Following on from the highly successful BCT-ETX-C3, the Blue Chip Technology ETX CN700 Single Board
computer integrates the latest advances in processor, graphics, memory, and I/O technologies to provide not
only an ideal platform for new embedded designs, but also a means of upgrading existing ETX based
applications to take advantage of the latest technologies.
The board is available with CPU build options of Ultra Low Voltage VIA Eden 500Mhz, VIA C7 nanobga2
1GHz and the VIA C7 nanobga2 1.5GHz processors. On-board voltage regulator circuits provide the required
voltages for the processor from the incoming 5 volt power supply. The 500MHz version is targeted at lower
cost, power conscious, performance driven applications. Where reduced power is less of a requirement then the
1GHz and 1.5GHz versions offer a higher performance solution.
Further additions to the range are the VIA Nano-E series processors which both support 64bit OS’s: the Low
Power 800MHz U3400, and the 1.3GHz U3100
The processor maintains full backward compatibility with the 8086, 80286, i386 and Intel486 processors. It
supports both read and write burst mode bus cycles, and includes separate on-chip code and data caches which
employ a write-back policy. Cache is integrated within the CPU and operates at the full CPU frequency giving
excellent performance. On the Eden/C7 CPU’s, cache size is 128K L1 and 128K L2, while on the Nano, cache
size is 64KB (data) +64KB (instruction) L1 and 1024KB L2. Also integrated into the processor is an advanced
numeric co-processor which significantly increases the speed of floating point operations, whilst maintaining
backward compatibility with Intel486 math co-processor and complying with ANSI/IEEE standard 754-1985.
The memory interface supports up to 1GB of DDR2 SDRAM, in a standard 200 pin SODIMM socket.
The ETX CN700 utilises the VIA CN700 Northbridge and VT8237R Pus Southbridge to integrate many
peripherals. These include: VGA controller with CRT, LVDS and LCD interfaces, ATA-100 IDE interface,
10/100 Fast Ethernet controller, floppy disk interface, quad USB ports, dual serial ports, parallel port, real-time
clock, keyboard and mouse (PS/2) controller, AC’97 audio interface. Connection to these functions is made
through a standard set of ETX connectors onto a base board. The base board can then bring these signals to
either Industry standard or customer specified connectors. The base board may be a custom design, developed
for a specific application or a standard solution offered by Blue Chip Technology. The VT8237R also provides
SATA interface which is accessed via two SATA connectors positioned on the ETX CN700 SBC in accordance
with the ETX V3.02 specification.
The ETX CN700 also has an on board USB connector which is only available to allow access to custom form
factor Flash drives. Note. This is not a standard USB port and will not work with non flash devices
The ETX-CN700 will drive up to four external PCI cards, all of which can perform Bus Mastering. Further IO
expansion is available through the 16-bit ISA bus.

ETX-CN700 Precautions
Page | 9
General Precautions
Your Single Board Computer is susceptible to damage by electrostatic discharges. In order to avoid damage,
you should work at an anti-static bench and observe normal anti-static precautions. Wear an anti-static wrist
strap connected to an earth point before opening any packaging.
Where a wrist strap is not available, discharge any static charge you may have built-up by touching an earth
point. Avoid any further movement that could build up another static charge. Touch an earth point from time to
time to avoid further build-up, and remove the items from their anti-static bags only when required
PS/2 Devices
It is important that PS/2 devices (mouse and keyboard) are not connected or disconnected with the unit powered
on. Damage or data corruption may occur if this precaution is not observed.
Electro-Static Discharges
If you are going to open up the unit, it is important to realise that the devices on the cards within this unit can be
damaged by static electricity. Bear in mind that the damage caused by static electricity may vary from total
destruction to partial damage, which may not be immediately obvious. This could have an effect on the
product's reliability and warranty. Before opening the chassis, ensure that you take necessary static precautions.
Ideally you should work at an anti-static bench and wear an approved wrist strap or if that is not possible, touch
a suitable ground to discharge any static build up before touching the electronics. This should be repeated if the
handling continues for any length of time.
If it is necessary to remove a board or electronic assembly, place it into an anti-static bag. This will prevent any
static electricity build up damaging the board. Metallised bags are preferred. Do not use black anti-static bags
for any item containing a battery because these tend to be conductive and will discharge the battery.
On-Board Battery
The ETX-CN700 board is does not have an on-board Lithium cell connected, however the base board to which
it connects may be equipped with a cell. Great care should be taken with this type of battery. If the battery is
mistreated in any way there is a very real possibility of fire, explosion, and personal harm. Under NO
circumstances should it be short-circuited, exposed to temperatures in excess of 100°C or burnt, immersed in
water, recharged or disassembled.
Expired batteries remain hazardous and must be disposed of in a safe manner, according to local regulations.
Le panneau de processeur est équipé d’une batterie de lithium. Le grand soin devrait être pris avec ce type de
batterie. Si la batterie est mistreated il y a de dans de toute façon un possibility très vrai du feu, d’expolosion et
de mal personnel. Dans au cunes circonstances il est sous peu circuité, exposé aux températures au dessus de
100 degrés de centrigrade ou brûlé, immergé dans l’eau, rechargée ou dissassambled.
Les batteries expirées restent dazaedous et doivent être reejetées d’une façon sûre, selon des règlements locaux.

ETX-CN700 Precautions
Page | 10
BIOS & CMOS Memory
Please be aware that with personal computer products, it is possible to create configurations within the BIOS
make booting impossible. Unlike most personal computer products, the ETX-CN700 stores the BIOS settings in
Flash memory rather than CMOS which allows these settings to be remembered even if there is no battery
present.
If settings are used which make the ETX-CN700 unstable, then clearing the CMOS as in other personal
computers to return to defaults will not work. The only way to reset default BIOS settings is to enter BIOS at
boot time and Load Default Settings.
WARNING: If you are uncertain as to consequences of making specific changes to BIOS settings, then consult
Blue Chip Technology Technical Support for advice
Electromagnetic Compatibility
This product has been assessed operating in representative, standard configurations. As with any PC product,
however, final installation & configuration can vary significantly, and so the following guidelines are offered to
help ensure that compatibility is maintained.
All components added to a system should either carry appropriate equivalent levels of compliance, or
be tested for compliance as part of the final system, and should be installed in accordance with supplier
recommendations.
The external enclosure should be securely fastened (with standard lids and covers in place) to ensure
good metal-to-metal contact around the internal electronics
Any metal back plate must be securely screwed to the chassis of the computer to ensure good metal-to-
metal (i.e. earth) contact.
Metal, screened, connector bodies should be securely connected to the enclosure.
The external cabling to boards causes most EMC problems. It is recommended that any external
cabling to the board be totally screened, and that the screen of the cable connects to the metal end
bracket of the board or the enclosure and hence to earth. Round, screened cables with a braided wire
screen are used in preference to those with a foil screen and drain wire. Wherever possible, use metal
connector shells that connect around the full circumference of the cable screen: they are far superior to
those that earth the screen by a simple “pig-tail”.
The keyboard and mouse will play an important part in the compatibility of the processor card since
they are ports into the board. Similarly, they will affect the compatibility of the complete system. Fully
compatible peripherals must be used otherwise the complete system could be degraded. They may
radiate or behave as if keys/buttons are pressed when subject to interference. Under these
circumstances it may be beneficial to add a ferrite clamp on the leads as close as possible to the
connector. A suitable type is the Chomerics type H8FE-1004-AS.
USB cables should be high quality screened types.
Ensure that the screens of any external cables are bonded to a good RF earth at the remote end of the
cable.
Failure to observe these recommendations may invalidate the EMC compliance.

ETX-CN700 Quick Start
Page | 11
Quick Start
The following sections explain how to install the ETX-CN700 Single Board Computer onto your host board.
As this single board computer can be installed onto a variety of host boards, the BlueChip Technology
MagnumX product has been used as an example host board.
First ensure that you are familiar with the contents of the section "Precautions". It contains important
information to avoid damage to the board.
Next, read the appropriate documentation from your System Unit supplier on how to install or upgrade a
processor board into the intended system unit.
If choosing your own cooling solution for the CPU, then check the application notes for the particular CPU from
the VIA website to ensure that your solution is capable of cooling the processor throughout the desired operating
temperature range. Note that the upper operating limit of 60°C is for the board operation in free air, which
would equate to the air temperature inside an enclosure with the lid closed. It is important to ensure that the
operating temper inside the system unit in the vicinity of the processor board does not exceed the 60°C limit.
Some higher powered CPU options may have a lower operating limit than 60°C, so refer to individual
datasheets for precise operating conditions
If using SATA HDD or DVD, then be aware that the SATA ports on the ETX-CN700 are identified in BIOS as
“IDE 4” and “IDE 5” and that in order to boot from these devices, they need to be among the 8 devices in the
top “Boot Order Priority” field as shown below.
Note that, in order to promote a device from the “Excluded” section, then there must be 7 (or less) devices in the
“Boot Order Priority” field. If there are already 8 devices, then some need to be removed first in order to
promote others. Using the cursor, select the appropriate device and press “X”. This will Remove/Add the device
from the “Boot Order Priority” field as appropriate.

ETX-CN700 Installation

Assembly
Connector locations
Figure 1: Connector Locations
With an ETX Single Board Computer, the main connections for Keyboard, Mouse, Video, IDE, USB etc are
made via the Host Board. On the ETX CN700 there are only two direct connections, both of which are SATA
connectors.
Connection to the host board is with four Hirose plug connectors (part number FX8-100P-SV) which mate with
corresponding Hirose socket connectors (eg part number FX8-100S-SV). There are four mounting holes of
2.5mm diameter are available for securing the ETX CN700 to the host board
Refer to Appendix 1 for details of the connector pin descriptions
When installing or removing the ETX CN700 module onto the host board, ensure that all power has been
removed, including 5V stand- by if present and any external Lithium cell or RTC back-up battery.
Before assembling the ETX CN700 onto the host board, check if any pillars or mounting fittings need to be
fitted to the host board.
The Blue Chip Technology MagnumX product has 4 mounting pillars which must first be attached to the host
board as shown below in Figure 2.

ETX-CN700 Installation
Page | 13
Figure 2: ensure mounting pillars are fitted to host board
The next action is to carefully align the connectors of the ETX CN700 with those on the host board and
carefully press together.
Note: The Hirose connectors are offset from each other, so the ETX CN700 will only fit on one orientation.
Trying to force the ETX CN700 in the wrong orientation may damage the connectors
Figure 3: Align ETX CN700 connectors with the host board
If the memory module is not already fitted, then carefully fit the memory module onto the memory socket. The
socket is notched to indicate the orientation of the module
At this stage, the cooling solution should be applied. There are several different methods of cooling the ETX
CN700

ETX-CN700 Installation
Page | 14
Cooling
Efficient cooling is essential for long and reliable operation of any electronic equipment. The VIA
Eden/C7/Nano CPU, the VIA CN700 Northbridge and VIA VT8237 Southbridge do get hot in normal
operation, and in an elevated ambient temperature will require additional cooling. Cooling requirements will
vary with application, desired operating temperature, CPU load, and memory size and board orientation.
Mounting the PCB vertically will aid natural convection and create a chimney effect. Passive heat sinks can be
used for the CPU, Northbridge and Southbridge. A fan, whilst not always desirable, will provide a high degree
of cooling even for a relatively slow airflow.
Further options that may be considered are sinking heat to the chassis or enclosure and in extreme situations the
use of a heat pipe.
The CPU is equipped with an onboard thermal diode for temperature monitoring. A thermistor is available to
monitor the temperature of critical and potential hot spots on the board. Temperatures can be monitored in the
BIOS Set-up. If you wish to monitor these temperatures from your application please contact the Blue Chip
Technology Technical Support team.
When designing an enclosure, bear in mind that the greater the volume of air that can flow through the
enclosure, the greater the cooling effect and the lower the temperature rise above the ambient air temperature.
However, the volume produced by any fan will vary with the pressure against which it has to work. The
resistance to airflow (the back-pressure on the fan) will depend upon the enclosure, the mounting and
restrictions. Therefore, when mounting and cabling the board, it is essential that the free circulation of the
cooling airflow is not impeded.
The calculation of airflow through an enclosure is not straightforward, and depends on many factors. The
method of meeting the cooling requirements will be specific for each system. Consequently, the system builder
is responsible for ensuring adequate cooling. However, interpreting airflow volumes is not intuitive. As an aid
to selecting suitable cooling, the following example is offered. A 60 mm axial fan (such as a Papst type
612NGH) blowing over the board can supply up to 46 m3/hour when unrestricted. Restrictions to the airflow
will reduce this volume.
Blue Chip Technology offers several cooling solutions to help manage cooling:
Heat plate designed to allow contact with a larger cooling area such as direct contact with a metal
enclosure
A passive finned heatsink
An active solution based on the finned heatsink with a fan (12 m3/hour) attached
Using the example of MagnumX, the following pictures show how the Active solution can easily be applied
Figure 4: Position Heatsink above ETX CN700 module

ETX-CN700 Installation
Page | 15
The Active solution has thermal pads attached to the bosses on the base of the finned heatsink which make
direct contact with the surface of Northbridge, Southbridge and two voltage regulators to help dissipate heat into
the heatsink.
Figure 5: Heatsink bosses and thermal pads
Before fitting the active solution, it is necessary to spread some thermal grease to the surface of the boss which
will contact the CPU. Thermal grease is required as thermal pads provide less thermal conductivity than
required for the CPU. Note: the minimum amount of thermal grease should be used
Figure 6: secure the assembly using screws
To finish of the assembly, it is necessary to use screws to secure the active solution in place. This also protects
against the ETX coming unseated from the host board during operation

ETX-CN700 Installation
Page | 16
Stack Heights and Clearances
The MagnumX stack heights for the above example are shown below.
Figure 7: MagnumX with Active Cooling Stack dimensions
Stack heights will depend on the length of the Hirose connectors on the host board. For example, the MagnumX
uses longer connectors on the base board to allow for high components on the host board, so there is a board to
board gap of 10mm.
On another Blue Chip Technology host board, the BCT-Eval board, there are no components on the host board
in the ETX area, so lower height connectors are used. Consequently the board to board gap is only 3mm.
Using the above example, the overall height from the inside base of an enclosure to the top edge of the screw
would be 54mm. As the fan draws air down from the top and pushes out through the sides, in this instance, there
is a requirement for at least 25mm clear space above the fan to ensure the fan operates efficiently. This could be
achieved two ways: firstly, a gap of 25mm between the top of the fan and the inside of the top cover, or
secondly, the cover could be just above the fan, with ventilation holes in the cover to allow air to flow freely
into the fan as shown in Figure 8 below.
Figure 8: Example of Cover close to top of fan

ETX-CN700 Software Configuration
Page | 17
System Software
Operating System Install
A DVD-ROM is supplied with each board, containing most common operating system drivers. Bear in mind
that suppliers continually update their drivers, so it is always a good idea to check on the Internet for later ones.
The following websites are good starting points:
www.viaarena.com
www.viatech.com
www.intel.com
For example for a fresh install of Windows XP operating system, drivers can be installed as follows
First install the CN700 Chipset #1 drivers. This driver includes the graphics driver, and there are several choices
as to which particular driver to choose depending on your requirements. Refer to the readme file in the
Drivers\SBPC\ETXCN700\Chipset 1 sub directory for more information on the choices
Next install the Chipset 2 driver by executing the setup.exe file in the Drivers\SBPC\ETXCN700\Chipset 2
folder. This installs the necessary IDE/SATA/Raid driver for the VT8237 Southbridge device
For Audio driver, run the setup.exe file from the Drivers\SBPC\ETXCN700\Audio folder.
Lastly, for the LAN driver, use Device Manager and when prompted, point the install to the
Drivers\SBPC\ETXCN700\LAN\MS\X86 folder

Navigation through the various pages is fairly straightforward and hints are given at the bottom of each page.
In general, when on a page, use the Up (↑), Down (↓), Left (←) and right (→) arrows to move around the page,
use the Page Up <PgUp> or plus <+> key to increase the numeric value, the Page Down <PgDn> or minus <->
key to decrease the numeric value, and use the Enter <Enter> key to go to the sub menu for that particular
option.
When in a Sub Menu, pressing the escape <ESC> key will return to the parent menu
Caution: Changing settings to the wrong values can result in an unreliable or
non working unit.
