Power Supply Chapter: Connectors

3 Connectors
3.1 Power Supply
The power supply of the hardware module is effected via a 2x8-pin connector (Molex PS 43045-16xx,
mating connector: Molex PS 43025-16xx). The pins for 12 volt have the sole purpose of supplying one or
both fans with the necessary current. Thus, when no fan is installed, these pins have no function. COM3
RXD and TXD can also be used for connecting a second power supply unit, e. g. for UPS. As an ordering
option SMBus signals SCL/SDA can be provided (replacing COM3 TXD/RXD).

Chapter: Connectors CMOS battery

3.2 CMOS battery

The board ships with a CR2032 battery holder (Renata VBH2032-1) and 3V battery. Alternatively, an
external battery can be connected via a 2pin connector (JST B2B-EH-A, mating connector: EHR-2).

Pin Name Description

1 BATT battery 3.3 volt
2 GND ground

page 14 Beckhoff New Automation Technology CB2051

System Chapter: Connectors

3.3 System
Some typical signals for system control are provided through a 2x9 pin connector (JST B18B-PHDSS,
mating connector: PHDR-18VS). This connector combines signals for power button, reset, keyboard,
speaker, and several LEDs such as harddisk LED, touch screen LED, suspend LED, and three additional
LEDs which are driven by GPIOs. Of these three GPIO-LEDs, LED1 and LED2 are already provided with
a series resistor. As can be seen from the pinout table below, corresponding signals are often placed vis-
à-vis or at least near to each other.

Chapter: Connectors PISA Slot

3.4 PISA Slot

The CB2051 module requires a backplane board in which it is inserted using the PISA slot. This slot
combines PCI and ISA signals in one single connector which is useful in situations where limited space is
an issue. The CB2051 currently supports only PCI.

NOTE
Please note the unusual pin numbering scheme of the PISA slot. There is an "up row" (for ISA signals)
and a "low row" (for PCI signals). The former is divided into segments A through D while the latter is
divided into segments E through H (cf. the illustration above).

3.6 Memory
Conventional SO-DIMM200 memory modules, as familiar from notebook computers, are used to equip
the board with memory. For mechanical reasons it is possible that particular memory modules cannot be
employed. Please ask your distributor for recommended memory modules.
With currently available SO-DIMM200 modules a memory extension up to 2 GByte is possible (DDR2-
667).
All timing parameters for different memory modules are automatically set by BIOS.

Chapter: Connectors Touch Screen

3.17 Touch Screen

A key feature of the CB2051 is the possibility to connect a touch screen. Both 4-wire and 5-wire resistive
touch screens are supported. For receiving the relevant signals a 5 pin standard IDC socket connector
with a spacing of 2.54 mm is provided. If the connected touch screen is 4-wire then pin 1 will not be used.
Next to this connector is a jumper which, if shorted at boot time, triggers the NVRST-signal in the
controller, thereby resetting all parameters of NVRAM to default values.
Conversion to the respective connector of the touch screen must be provided externally. Please consult
the manufacturer’s documentation to figure out the relevant technical details.
Note: In the pinout table below H, X, S, Y, and L are the signal names in the case of 5-wire, XL, XR, YT,
and YB are the names in the case of 4-wire.

familiar audio in, audio out, and microphone. OS dependent device drivers can switch these signals to
support an 5.1 output; thus in this mode no audio input signals are available.
Signals "SPDIFI" and "SPDIFO" provide digital input and output. If a transformation to a coaxial or optical
connector is necessary this must be performed externally.

Remarks for Setup Use Chapter: BIOS Settings

4 BIOS Settings
4.1 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 further notice. The settings displayed in
the screenshots on the following pages are meant to be examples only. Neither do they represent the
recommended settings nor the default settings. What the appropriate settings are depends entirely on the
particular application scenario in which the board is used.

Load Fail-Safe Defaults Chapter: BIOS Settings

4.11 Load Fail-Safe Defaults

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.

4.12 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.

4.13 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.

4.14 Save & Exit Setup

Settings are saved and the board is restarted.

4.15 Exit Without Saving

This option leaves the setup without saving any changes.

Beckhoff New Automation Technology CB2051 page 65

Chapter: BIOS update Exit Without Saving

5 BIOS update
If a BIOS update becomes necessary, the program “AWDFLASH.EXE” of the company Phoenix 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 /cd /cp

/sn Do not save the current BIOS

/cc Clear the CMOS
/cd Clear the DMI information
/cp Clear the PnP information

The erasure of CMOS, DMI 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.
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

Thermal Specifications Chapter: Technical Data

7.3 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.
