2Introduction
2.1 JRex Embedded Line Family
JRex embedded line modules are characterized by the same surface pin-outs and interfaces for Reset logic
and ATX power supply feature, 2 x USB, Fast LAN, PS/2 Keyboard and Mouse connector, Compact-Flash
socket, VGA interface as well as one Serial Port. These embedded line family features allow the use of the
same chassis over the whole product line and maximize design reuse.
JRex embedded line modules allow the use of standard laptop memories and full ATX power supplies.
These homogeneous features facilitate easy upgrades within the JRex embedded line product family. Con-
nection of LCD panels is simplified when using the onboard standard JILI30 interface (Jumptec®In-
telligent LVDS Interface).
As part of the standard features package, all JRex embedded line modules come with a JIDA interface
(Jumptec®Intelligent Device Architecture), which is integrated into the BIOS of the SBC modules. This
interface enables hardware independent access to the JRex features that can't be accessed via standard
APIs. Functions such as watchdog timer, brightness of panel backlight and user bytes in EEPROM can be
configured with ease by taking advantage of this standard JRex module feature.

Temperature
Operating: (with Kontron Cooling Solution):
®Ambient temperature: 0 to +60°C 1)
®Non-operating: -10 to +85°C
Note: 1) The maximum operating temperature is the maximum measurable temperature on any spot on a module’s surface. You
must maintain the temperature according to the above specification.
Humidity
®Operating: 10% to 90% (non condensing)
®Non operating: 5% to 95% (non condensing)

MTBF
14
4MTBF
The following MTBF (Mean Time Between Failure) values were calculated using a combination of manufac-
turer’s test data, if the data was available, and a Bellcore calculation for the remaining parts. The Bellcore
calculation used is “Method 1 Case 1”. In that particular method the components are assumed to be
operating at a 50% stress level in a 40°C ambient environment and the system is assumed to have not been
burned in. Manufacturer’s data has been used wherever possible. The manufacturer’s data, when used, is
specified at 50°C, so in that sense the following results are slightly conservative. The MTBF values shown
below are for a 40°C in an office or telecommunications environment. Higher temperatures and other envi-
ronmental stresses (extreme altitude, vibration, salt water exposure, etc.) lower MTBF values.
®System MTBF (hours): tbd
Note: Fans usually shipped with Kontron Embedded Modules GmbH products have 50,000-hour typical operating life. The above
estimation assumes no fan, but a passive heat sinking arrangement. Estimated RTC battery life (as opposed to battery
failures) is not included in the MTBF calculation. The RTC battery lifetime has to be considered separately. Battery life
depends on both temperature and operating conditions. When the Kontron unit has external power; the only battery drain
is from leakage paths.drain is from leakage paths.

Getting Started
15
5Getting Started
Getting started with the JRexplus-DC is very easy. Take the following steps:
Connect the ATX-adapter (KAB-ATX-10) to the JRexplus-DC ATX power connector J35. The
location of connector J35 can be found in the Appendix A: "Connector Layout".
Plug a suitable DDR2-SDRAM memory module into the RAM socket.
Connect a DVI monitor to the DVI connector (the use of a VGA monitor with a DVItoVGA
adapter is also possible).
Plug a keyboard and/or mouse to the PS2 or USB connector(s).
Plug a Compact-Flash card into the Compact flash socket on the bottom of the board.
Connect an ATX power Supply
Make sure all your connections have been made correctly. Turn on the power by shortening
the power button pins on Front Panel Pin Header 1 (J36).
Enter the BIOS by pressing the Del key during boot-up. Make all changes in the BIOS Setup.
See the BIOS Setup chapter of this manual for details.
6System Memory
The JRexplus-DC uses only 200 pin Small Outline Dual Inline Memory Modules (SODIMMs). One socket is
available for 1.8V unbuffered DDR2-533 SDRAM of up to 2 GB.
Memory Modules with 667Mhz clock frequency can also be used. In this case the memory module is driven
with 533Mhz. It is recommended to use RAM-modules which have been approved by Kontron.
Please contact the board vendor to receive a list of approved memory modules.
The total amount of memory available on the SDRAM module is used for main memory and graphic memory
on the JRexplus-DC. Shared Memory Architecture (SMA) manages the sharing of the system memory
between graphic controller and processor. Therefore, the full memory size is not available for software
applications. Up to 128 MB of system memory are used as graphic memory. Depending on system memory
the graphic driver may allocate more.
Attention: Kontron Embedded Modules GmbH can't guarantee the correct functionality of theJRexplus-DC when a DDR2-module
with another frequency than 533Mhz is used.

Graphics Interface
16
7Graphics Interface
The graphics accelerator supports an Analogue Video Graphics Array Output (VGA) a SDVO interface
combined with a SDVO/DVI converter up to 160 MHz and a variety of LVDS LCD panels with dual channel and
color depths of 18bit. Each LVDS channel supports transmit clock frequency ranges from 25 to 112 Mhz.
7.1 DDC Interpretation
Depending on the jumper settings of J10 and J12 the DDC data deliverd by the display is either interpreted
for the VGA channel or for the DVI channel.
Important: Both Jumpers (J10 and J12) must be set to the same position.

7.3 Flat Panel Connector - JILI30
The LVDS interface for the flat panel is available through the JILI30 connector (30 pins) J4 on the bottom
side of the board. This connector represents the JILI interface (JUMPtec Intelligent LVDS Interface). The
implementation of this subsystem complies with the JILI specification of Kontron Embedded Modules
GmbH. A variety of cables for different display types are available from Kontron.

7.4 Panel Power Jumper
The Panel Power Jumper J2 sets the Panel supply voltage.
For the panel supply voltage a solder jumper is important. The board is delivered with the solder jumper
equipped as shown on the following picture:
3.3V/5V
Jumper J2
In this case the board is configured so that 3.3V or 5V Panel VCC can be selected with Jumper J2.
1
When a panel supply voltage of 12V is needed the solder jumper has to be set to the red marked position of
the following picture. It is important that the only one of those two solder jumpers is equipped. When the
12V solder jumper is set the 3.3V solder jumper has to be removed.
In this case the jumper setting (1-2) for 3.3V leads to a panel supply voltage of 12V.
Note: 1) All soldering works must be done in a professional production environment. To avoid loosing the qurantee for your
