Product Warranty (2 years)
Advantech warrants to you, the original purchaser, that each of its prod-
ucts will be free from defects in materials and workmanship for two years
from the date of purchase.
This warranty does not apply to any products which have been repaired or
altered by persons other than repair personnel authorized by Advantech,
or which have been subject to misuse, abuse, accident or improper instal-
lation. Advantech assumes no liability under the terms of this warranty as
a consequence of such events.
Because of Advantech’s high quality-control standards and rigorous test-
ing, most of our customers never need to use our repair service. If an
Advantech product is defective, it will be repaired or replaced at no
charge during the warranty period. For out-of-warranty repairs, you will
be billed according to the cost of replacement materials, service time and
freight. Please consult your dealer for more details.
If you think you have a defective product, follow these steps:
1. Collect all the information about the problem encountered. (For
example, CPU speed, Advantech products used, other hardware
and software used, etc.) Note anything abnormal and list any
onscreen messages you get when the problem occurs.
2. Call your dealer and describe the problem. Please have your man-
ual, product, and any helpful information readily available.
3. If your product is diagnosed as defective, obtain an RMA (return
merchandize authorization) number from your dealer. This allows
us to process your return more quickly.
4. Carefully pack the defective product, a fully-completed Repair and
Replacement Order Card and a photocopy proof of purchase date
(such as your sales receipt) in a shippable container. A product
returned without proof of the purchase date is not eligible for war-
ranty service.
5. Write the RMA number visibly on the outside of the package and
ship it prepaid to your dealer.

1.1 Introduction
The TPC-1250H touch panel computer is a state-of-the-art HMI (Human
Machine Interface). This operator interface with a 12.1” display is an
x86-based platform with these key features:
• Fanless
By using a low-power processor, the system does not have to rely on
fans, which often are unreliable and causes dust to circulate inside the
equipment.
• Bright Display
The TFT LCD display suits industrial demands for clear interfaces.
• Web-based Terminal Solution
TPC-1250H is design for Web-base terminal solution, so JavaScript is
include in Windows operating system.

Figure 2.4: Power Receptor & Button Pin Assignment
Warning It is suggested to turn OFF system power as you
plug in or pull out the memory card, even though
the CompactFlash memory is hot swappable.

Installing the Drivers
After installing your system software, you will be able to set up the Ether-
net, SVGA, and touchscreen functions. All drivers are stored in a CD-
ROM disc entitled “TPC-1250H” which can be found in your accessory
box.
The various drivers in the CD-ROM disc have their own text files which
help users install the drivers and understand their functions. These files
are a very useful supplement to the information in this manual.
Note: If you want to install the touchscreen driver & use
the touchscreen utility, please refer the user
manual which is "PenMount 6000 Installation
Guide" in the CD-ROM.
Note The drivers and utilities used for the TPC-1250H panel PCs
are subject to change without notice. If in doubt, check
Advantech's website or contact our application engineers

Chapter 3 Features in Windows XP
Embedded
TPC-1250H supports the embedded Windows platform. This section out-
lines the important features (EWF and HORM), that are provided in Win-
dows XP embedded.
3.1 EWF
EWF stands for Enhanced Write Filter. It provides an upper filter in the
storage device driver stack that redirects disk write operations to volatile
(RAM) or non-volatile (disk) storage. EWF protects a volume from write
access. The benefits are as the following.
Write-protect one or more partitions on your system.
Enable read-only media, such as CD-ROM or flash, to boot and run.
Prolong the lifespan of write-sensitive storage, such as CompactFlash.
TPC-1250H XPE provides EWF RAM RDG mode on system partition.
All wirte to system partition will be redirected to RMA once this mode is
enabled. This mode is manually enabled by customers after they finish
all their changes on system such as installing their applications or adjust-
ing system setting.
Advantech provides a pair of utilities to operate EWF, OSLock and
OSUnLock. The setting is stated in the section later.
