Notice:
1. The changes or modifications n ot expressly approved by th e party responsible for compliance could void the user’s authority
to operate the eq uipment.
2. Shielded interface cables must be used in or der to comply with the emission limits.
Static Electricity Precautions
It is quite easy to inadvertently dam age the system board, components or devices even before installing
them in your system unit. Static electrical discharge can damage computer components wi thout causing
any signs of physical damage. You must take extra care in handling them to ensure against electrostatic
build up.
1. To prevent electrostatic build up, le ave the system board in its anti-static bag until you are ready to install
it.
2. Wear an antistatic wrist st rap.
3. Do all preparation work on a static-free surface.
4. Hold the device only by its edges. Be careful not to touch any of the components, contacts or
connections.
5. Avoid touching the pins or contacting all modules and connectors. Hold modules or connectors by their
ends.
Important:
Electrostatic discharge (ESD) can damage your p rocessor, disk drive and other components. Perform the upgrade instruction
procedures described at an ESD wor kstation only. If such a station is not available, you can provide some ESD protection by
wearing an antistatic wrist strap and attaching it to a metal part of the system chassis. If a wrist strap is unavailable, es tablish
and maintain contact with the system chassis throughout any procedures requiring ESD protection.

Safety Measures
To avoid damage to the system:
• Use the correct AC input voltage range to reduce the risk of electric shock.
• Unplug the power cord before removing the system chassis cover for installation or servicing. After
installation or servicing, cover the system chassis before plugging the power cord.
Battery:
• Danger of explosion if battery incorrectly replaced.
• Replace only w ith the same or equivalent type recommend by the manufacturer.
• Dispose o f used batteries according to local ordinance.
Warranty
1. Warranty does not cover damages or failures caused b y misuse of th e p roduct, inability to use the
product, unauthorized replacem ent or any kind of alterations of components an d product
specifications.
2. The warranty is voided if the product has been exposed to physical abuse, improper installation, a ny
kind of modification, acc idents or unauthorized repair of the p roduct.
3. Unless otherwise instructed in this user manual, the user m ay not, under any circumstances, attempt to

The new FES2215 provides customer a choice of Atom D2550 / N2800 / N2600 Processor, depends on
the model being selected. FES2215 has applied by the r ecent launched Atom™Pr ocessor D2550 Dualcor e 1.86 GHz Pr ocessor, w hich deliveries enhanced performancein mult i -media capabil i ty on the
market at the pr esent moment and it offers to reach the maximum m emory size up to 4 GB DDR3800/ 1066 while ast he graphic clock speed of 640 MHz. FES2215 supportsfor dual display of VGA and
HDMI. Furthermore, while as t he new FES2215 is equipped of NM10 South BridgeChipset , w hich
deli ver ies high speed st orage int erface that suppor ts for fast er data tr an sferr ing r ate as to increase
efficiency
In order to meet the networ k stability, the FES2215 ser ies use two Realtek 81xx 100/ 1000 Mbps LAN
with Wake-On LAN & DMI to support and maintain Ethernet function. The system designed wi th two
DB-9; one supports for RS-232/ 422/ 485 and one supports for RS-232 interface, an d one RJ-45
supports for RS-232. There are threeof DB-9 for RS-232 reser ved for optional expansion avai lability.
A software pr ogramming Watchdog (WDT) wi t h timer r ange from 1 to 255 seconds is enabled in Pipal
2215. For t he audio output , there has occupied wit h an ALC662 for speaker.
The power supply is capable for DC power i nput of 12V or 24V. The power consumption is able to
reach up to 22W in maximum. The system is valuable for all the embedded appl ications, and also
well support wit h t he Window 7, Window s XP and Linux Operation system.
The new FES2215 is not only capable and r eliable to offer you an unprecedented experi ence with
extr emely high graphic perfor mance along wit h remainin g low on power consumpt ion but also

Chapter 3: UEFI Setup Utility
3-1 Introduction
This section explains how to use the U EFI SETUP UTILITY to configure yours system. The UEFI chip on the
motherboard stores the U EFI SETUP UTILITY. You may run the UEFI SETUP UTILITY when you start up the
computer. Please press <F2> or <Delete> during the Power-On-Self-Test (POST) to enter the U EFI SETUP
UTILITY, otherwise, POST will continue with its test routines.
If you wish to enter the UEFI SETUP U TILITY after POST, restart the system by pressing <Ctl> + < Alt> +
<Del ete>, or by pressing the reset button on the system chassis. You may also restart by turning the syste m off
And then back on.
3-1.1 UEFI Menu Bar
The top of the screen has a menu bar with the following selections:
Main: For setting system time/date inform ation
OC Tweaker: For over-clocking configurations

Chapter 4: Installation Guide
4-1. Memory Modules (SO-DIMM)
Pipal 2215 provides two 240-pin DDR3 SO-DIMM slots.
- It is NOT allow ed to install a DDR or DDR2 memory module into a DDR 3 slot; otherwise, the
motherboard and SO-DIMM may be d amaged.
- Ple ase install the mem ory module from DDR3_A 2 slot as the 1stpriority.
4-1.1 Installing a SO-DIMM
Please make sure to disconnect the power supply before adding or removing SO-DIMMs or the
system components.
STEP 1: Unlock a SO-DIMM slot by pressing the retaining clips outward.
STEP 2: Align a SO-DIMM on the slot such that the notch on the SO-DIMM matches the break on the slot.
The SO-DIMM only fits in one correct orientation. It will cause p ermanent damage to the
motherboard and the SO-DIMM if you force the SO-DIMM into the slot in the incorrect orientation.
STEP 3: Firm ly insert the SO-DIMM into the slot until the retaining clips at both ends fully snap back in
place
and the SO-DIMM is properly seated.

4-2. Expansion Slot (PCI Slot)
There is 1 Mini-PCI-E expansion slot for FES 22 15.
PCI Slot: The PCI slot is used to install an expansion card that has 32-bit PCI interface.
4-2.1 Installing an expansion card
STEP 1: Before installing the expansion card, please make sure that the power supply is switche d off or
the power cord is unplugged. Please read the documentation of the expans ion card and make necessary
hardware setting for the card before you start the installation.
STEP 2: Rem ove th e system unit cover.
STEP 3: Rem ove the bracket facing the slot that you intend to use. Keep the screws for later use.
STEP 4: Align the card connector with the slot and press firmly until the card is completely seated on the
slot.
STEP 5: Fasten the card to the chassis with screws.
STEP 6: Replace the system cover.
