3 Connectors
This section describes all the connectors found on the CB4052.
CAUTION
For most interfaces, the cables must meet certain requirements. For instance, USB 2.0 requires twisted
and shielded cables to reliably maintain full speed data rates. Restrictions on maximum cable length are
also in place for many high speed interfaces and for power supply. Please refer to the respective
specifications and use suitable cables at all times.

Power Supply Chapter: Connectors
3.2 Power Supply
The power supply of the hardware module is realized via a 2x5-pin connector (Molex PS 43045-10xx,
mating connector: Molex PS 43025-10xx). Both 5V VCC/SVCC and 12V need to be provided. The 12V
input can optionally be tied to 5V if 12V is not required by attached peripherals. It cannot, however, be left
unconnected.
CAUTION
The CB4052 includes circuitry that will notify an intelligent power supply to shut down if the processor
reaches a critical temperature. This is achieved by deasserting the (low-active) PS_ON# signal found on
the SM-Bus connector. When PS_ON# is no longer pulled low, an intelligent power supply would take this
as a signal to shut down power. For this to work, PS_ON# must be connected to the power supply's
PS_ON input. If PS_ON# is not otherwise connected, the CB4052 can be damaged beyond repair if a
thermal shutdown event occurs. In rare instances, if power is not shut down, the board will continue to
heat up until failure occurs.
NOTE
Since this is a 90 degree connector, the symbol in the drawing below represents the connector face as
seen from the side (PCB on bottom) rather than from above.

Memory Chapter: Connectors
3.4 Memory
There is one conventional SO-DIMM204 socket available to equip the board with memory (DDR3-1066).
It is located on the bottom side of the board. For technical and mechanical reasons it is possible that
particular memory modules cannot be employed. Please ask your sales representative for recommended
memory modules.

The LCD is connected via two 15 pin connectors (Hirose DF13-15P-1.25DSA, mating connector:
DF13-15S-xxx). The power supply for the display is also provided through these connectors. The CB4052
board only supports displays with LVDS interface. For displays with digital interface an extra receiver
board is available. There is no support for DSTN displays.
With the LVDS interface it is possible to trigger LVDS displays with a maximum of 24 Bit colour depth
and one or two pixels per clock. For single pixel displays only one connector is necessary. However, if
you want to read the display's EDID data the second connector must be connected.
The display type can be chosen over the BIOS setup. Please contact your sales representative regarding
an appropriate cable to connect your display.

Chapter: BIOS Settings Remarks for Setup Use
5 BIOS Settings
5.1 Remarks for Setup Use
In a setup page, standard values for its setup entries can be loaded. Fail-safe defaults are loaded with F6
and optimized defaults are loaded with F7. These standard values are independent of the fact that a
board has successfully booted with a setup setting before.
This is different if these defaults are called from the Top Menu. Once a setup setting was saved, which
subsequently leads to a successful boot process, those values are loaded as default for all setup items
afterwards.
See also the chapters “Load Fail-Safe Defaults" (5.10) and “Load Optimized Defaults” (5.11).
NOTE
BIOS features and setup options are subject to change without notice. The settings displayed in the
screenshots on the following pages are meant to be examples only. They do not represent the
recommended settings or the default settings. Determination of the appropriate settings is dependent
upon the particular application scenario in which the board is used.
5.2 Top Level Menu

Board Revision 1
If this option is chosen, the last working setup is loaded from flash. Working means that the setup setting
has already led to a successful boot process.
At the first setting of the BIOS setup, safe values are loaded which lets the board boot. This status is
reached again, if the board is reprogrammed with the corresponding flash-program and the required
parameters.
5.12 Load Optimized Defaults
This option applies like described under “Remarks for Setup Use” (5.1).
At first start of the BIOS, optimized values are loaded from the setup, which are supposed to make the
board boot. This status is achieved again, if the board is reprogrammed using the flash program with the
required parameters.
5.13 Set Password
Here you can enter a password to protect the BIOS settings against unauthorized changes. Use this
option with care! Forgotten or lost passwords are a frequent problem.
5.14 Save & Exit Setup
Settings are saved and the board is restarted.
5.15 Exit Without Saving
This option leaves the setup without saving any changes.
Beckhoff New Automation Technology CB4052 page 61
Chapter: BIOS update Exit Without Saving
6 BIOS update
If a BIOS update becomes necessary, the program “AWDFLASH.EXE” from Phoenix Technologies is
used for this. It is important, that the program is started from a DOS environment without a virtual memory
manager such as for example “EMM386.EXE”. In case such a memory manager is loaded, the program
will stop with an error message.
The system must not be interrupted during the flash process, otherwise the update is stopped and the
BIOS is destroyed afterwards.
The program should be started as follows:
awdflash [biosfilename] /sn /cc /cp
/sn Do not save the current BIOS
/cc Clear the CMOS
/cp Clear the PnP information
The erasure of CMOS and PnP is strongly recommended. This ensures, that the new BIOS works
correctly and that all chipset registers, which were saved in the setup, are reinitialized through the BIOS.
DMI should only be erased (option /cd) if the BIOS supplier advises to do so.
A complete description of all valid parameters is shown with the parameter “/?”.
In order to make the updating process run automatically, the parameter “/py” must be added. This
parameter bypasses all security checks during programming.
CAUTION
Updating the BIOS in an improper way can render the board unusable. Therefore, you should only update
the BIOS if you really need the changes/corrections which come with the new BIOS version.
CAUTION
Before you proceed to update the BIOS you need to make absolutely sure that you have the right BIOS
file which was issued for the exact board and exact board revision that you wish to update. If you try to
update the BIOS using the wrong file the board will not start up again.

Thermal Specifications Chapter: Technical Data
8.3 Thermal Specifications
The board is specified to operate in an environmental temperature range from 0°C to +60°C (extended
temperature on request). Maximum die temperature is 100°C. To keep the processor under this threshold
an appropriate cooling solution needs to be applied. This solution has to take typical and maximum power
consumption into account. The maximum power consumption may be twice as high and should be used
as a basis for the cooling concept. Additional controllers may also affect the cooling concept. The power
consumption of such components may be comparable to the consumption of the processor.
The board design includes thermal solution mounting points that will provide the best possible thermal
interface between die and solution. Since we take thermal solutions seriously we have several advanced,
aggressive cooling solutions in our product portfolio. Please contact your sales representative to order or
discuss your thermal solution needs.
CAUTION
The end customer has the responsibility to ensure that the die temperature of the processor does not
exceed 100°C. Permanent overheating may destroy the board!
In case the temperature exceeds 100°C the environmental temperature must be reduced. Under certain
circumstances sufficient air circulation must be provided.
CAUTION
The CB4052 includes circuitry that will notify an intelligent power supply to shut down if the processor
reaches a critical temperature. This is achieved by deasserting the (low-active) PS_ON# signal found on
the SM-Bus connector. When PS_ON# is no longer pulled low, an intelligent power supply would take this
as a signal to shut down power. For this to work, PS_ON# must be connected to the power supply's
PS_ON input. If PS_ON# is not otherwise connected, the CB4052 can be damaged beyond repair if a
thermal shutdown event occurs. In rare instances, if power is not shut down, the board will continue to
heat up until failure occurs.

C Interrupt
The used resources depend on setup settings.
The listed interrupts and their use are given through AT compatibility.
If interrupts must exclusively be available on the ISA side, they have to be reserved through the BIOS
setup. The exclusivity is not given and not possible on the PCI side.
All listed PCI devices exist on the board. Some PCI devices or functions of devices may be disabled in
the BIOS setup. Once a device is disabled other devices may get PCI bus numbers different from the
ones listed in the table.
