source of problems due to resource conflicts. If a board is defective, it can be sent to your supplier for repair.
Please take care of the following steps:
1. The board returned should have the factory default settings since a test is only possible with these set-
tings.
2. In order to repair your board as fast as possible we require some additional information from you
(detailed description of how and when did the problem occur, what is exactly the problem and so on).
3. Upon receipt of returned boards please be aware that your user specific settings could have been
changed during repair.
Within the warranty period the repair is free of charge as long as the warranty conditions are observed.
Because of the high test expenditure you will be charged with the test cost if no fault is found. Repair after the
warranty period will be charged.

2. INTRODUCTION
2.1. Kontron ePanel-Concept
Time is something no one has enough. „Short time-to-market“ is a nightmare everybody suffers from. A new
concept promises a lot of advantages, but how to use them in a non existent time span? Especially embedded
boards are not always easy connectable, think of tangling cables or missing adapters. Kontron recognized this
problem and developed the ePanel, a platform for OEM and ODM. Its main benefit is the high integration of
mobile accessories and components in conjunction with mechanical fit and function. To build a mobile
computer, just use a battery, TFT display, inverter and housing and you‘re set. Now system design and appli-
cation development gets a great boost forward. Others still look for adapters while your project already started.
In order to stay close to state-of-the-art computer technologies of the desktop PC market, the ECT business
(Embedded Computer Technology) demands adequate processor performance for many applications. There
are many standards for CPU boards with a lot of advantages or restrictions. Unfortunately none of these
products care about the increasing customer specialization. A board, which fits exactly into a system, is nearly
impossible to find but ePanel fits nearly for all mobile and space critical applications. Only a customized module
will fulfill all requirements. But away from standard products, a customer has to tolerate long development
cycles and costly problems with quick replacements or easy upgrades. The way out of this situation has to join
two apparent opposites. The task is to create a customized PC board out of standard parts. Obviously the
solution has to be modular. The answer of Kontron for the mobile business: ePanel.
Quick integration and nevertheless standard PC technology.
The ePanel-mgx is a complete Pentium®class PC with standard interfaces including USB and additional
options such as sound capabilities, PC-Card, Touch & Matrix controller, TV-In and -Output, Flatpanel interface,
and 100 MBit Ethernet, etc.
Smallest Dimensions to meet smallest space requirements.
With 252 cm2the ePanel-mgx uses only a little more space compared to a current slot CPU, which needs 219
cm2. But the most surprising fact is the module height. The ePanel-mgx measures only 10 mm!
How about the ISA bus?
The only way to extend the capabilities of the board is to plug in PC-Cards. No other bus systems are
supported.
There must be replacements or upgrades for future requirements.
Kontron will expand and improve this innovative and handy ePanel concept. New PC technologies will be
obtainable the same way as in other Kontron product families.
An ePanel board does not force you in excessive and expensive cabling. Only the really demanded interfaces
are linked to the corresponding connectors. The decision is up to you, which one you call for or which one to
skip. Evaluation adapters and kits are available.
The application requests low power Pentium®performance.
Don‘t worry about that. Depending on OS and used options, the ePanel-mgx consumes between 5.8 Watts
depending on input voltage
Finally the system passed all the tests and now?
Nothing special, just start mass production. Kontron knows about the short life cycles of PC products.
Therefore we secured by suitable methods, that longevity is one of the most excellent characteristics of the
ePanel family.

Technical Manual ePanel-mgx Introduction
Page 6 of 45 Pages
2.2. ePanel-mgx
The ePanel-mgx is an extreme compact National Semiconductor® Geode™ SC1200 based PC module with
consistent low power design. The National Semiconductor® Geode™ SC1200 processor allows the usage of
the board without active or passive cooling in applications, where space limitations (the maximum height is only
10 mm!) are major requirements. It is now possible to create modular systems, combining exchangeable CPU
performance with systems, carrying only the connectors and additional functions needed. This reduces
development costs and speeds up application design. Despite the very little board dimensions, the ePanel-mgx
offers all standard interfaces such as Sound, Ethernet, USB and Graphic. The fully compliant AC97 soundchip
is supported by most operating systems. For networking purposes the ePanel-mgx comes with a 10/100 MBit
Ethernet controller which allows an easy Intranet/Internet access. Total communication interfaces like 2 serial
TTL ports, an EPP parallel port, Floppy-interface, Touch & Matrix controller, TV-In and -Output, 3 USB ports,
PC-Card controller, 10/100 Mbit Ethernet, battery charger for smart batteries and a wide range DC power
supply. A full function graphics accelerator contains a VGA (video graphics array) controller, bitBLT engine,
and a ROP (raster operations) unit for complete GUI (graphical user interface) acceleration under most
operating systems. You‘re looking for a secure and EMI tolerant boot medium? A Compact Flash socket for
commercial CF-cards is already integrated on the module. For further expansions one additional IDE port is
available.
