With the ATX mode selected, the ACT-457A panel PC goes in a standby mode when it is
turned off. The panel PC can be easily turned on via network or a power switch in standby
mode. Remote power control is perfect for advertising applications since the
broadcasting time for each panel PC can be set individually and cont rolled remotely . Other
possible application includes
With the AT mode selected, the power is controlled by a central power unit rather than a
power switch. The ACT-457A panel PC turns on automatically when the power is
connected. The AT mode benefits a production line to control multiple panel PCs from a
central management center and other applications including:

Page 41
4.1 System Maintenance Introduction
If the components of the ACT-457A fail they must be replaced. Components that can be
replaced include:
SD card
Wireless LAN module
SO-DIMM module
Please contact the system reseller or vendor to purchase the replacement parts. Back
cover removal instructions and component replacement for the ACT-457A are described
below.
4.2 Anti-static Precautions
ACT-457A Panel PC
WARNING:
Failure to take ESD precautions during the maintenance of the
ACT-457A may result in permanent damage to the ACT-457A and
severe injury to the user.
Electrostatic discharge (ESD) can cause serious damage to electronic components,
including the ACT-457A. Dry climates are especially susceptible to ESD. It is therefore
critical that whenever the ACT-457A is accessed internally, or any other electrical
component is handled, the following anti-static precautions are strictly adhered to.
Wear an anti-static wristband: Wearing a simple an ti-static wristband can
help to prevent ESD from damaging the board.
Self-grounding: Before handling the board, touch any grounded conducting
material. During the time the board is handled, frequently touch any
conducting materials that are connected to the ground.
Use an anti-static pad: When configuring the ACT-457A, place it on an
Page 42
antic-static pad. This reduces the possibility of ESD damaging the ACT-457A.
Only handle the edges of the PCB: When handling the PCB, hold the PCB
by the edges.
ACT-457A Panel PC
4.3 Turn off the Power
WARNING:
Failing to turn off the system before opening it can cause permanent
damage to the system and serious or fatal injury to the user.
Before any maintenance procedures are carried out on the system, make sure the system
is turned off.
4.4 Rear Panel Removal
To access the jumpers and connectors, the rear panel must be removed.
Step 1: Turn off and disconnect the power from the ACT-457A.
Step 2: Place the ACT-457A monit or sid e down on a flat surface.
Step 3: Remove the rear panel screws and lift the back cover off. Step 0:

4.5.2 Motherboard Replacement
A user cannot replace a motherboard. If the motherboard fails it must be shipped back to
IEI to be replaced. If the system motherboard has failed, please contact the system
vendor, reseller or an IEI sales person directly.

Audio Codec 97 (AC’97) refers to a codec standard developed by Intel®
in 1997.
Advanced Configuration and Power Interface (ACPI) is an OS-directed
configuration, power management, and thermal management interface.
Advanced Host Controller Interface (AHCI) is a SATA Host controller
register-level interface.
The Advanced Technology Attachment (ATA) interface connects storage
devices including hard disks and CD-ROM drives to a computer.
An ATAPI Removable Media Device (ARMD) is any ATAPI device that
supports removable media, besides CD and DVD drives.
Amplitude Shift Keyed Infrared (ASKIR) is a form of modulation that
represents a digital signal by varying the amplitude (“volume”) of the
signal. A low amplitude signal represents a binary 0, while a high
amplitude signal represents a binary 1.
The Basic Input/Output System (BIOS) is firmware that is first run when

The Compressor-Decompressor (CODEC) encodes and decodes digital
audio data on the system.
CompactFlash® is a solid-state storage device. CompactFlash® d evices
use flash memory in a standard size enclosure. Type II is thicker than
Type I, but a Type II slot can support both types.
Complimentary metal-oxide-conductor is an integrated circuit used in
chips like static RAM and microprocessors.
COM refers to serial ports. Serial ports offer serial communication to
expansion devices. The serial port on a person al computer is usually a
male DB-9 connector.
The Digital-to-Analog Converter (DAC) converts digital signals to analog
signals.
Double Data Rate refers to a data bus transferri ng data on both the rising
and falling edges of the clock signal.

Direct Memory Access (DMA) enables some peripheral devices to
bypass the system processor and communicate directly with the system
memory.
Dual Inline Memory Modules are a type of RAM that offer a 64-bit data
bus and have separate electrical contacts on each side of the module.
The digital inputs and digital outputs are general control signals that
control the on/off circuit of external devices or TTL devices. Data can be
read or written to the selected address to enable the DIO functions.
The Enhanced Host Controller Interface (EHCI) specification is a
register-level interface description for USB 2.0 Host Controllers.
Enhanced IDE (EIDE) is a newer IDE interface standard that has dat a
transfer rates between 4.0 MBps and 16.6 MBps.
Enhanced Intel® SpeedStep Technology (EIST) allows users to modify
the power consumption levels and processor performance through
application software. The application software changes the bus-to-core

The Front Side Bus (FSB) is the bi-directional communication channel
between the processor and the Northbridge chipset.
Gigabit Ethernet (GbE) is an Ethernet version that transfers data at 1.0
Gbps and complies with the IEEE 802.3-2005 standard.

Hard disk drive (HDD) is a type of magnetic, non-volatile computer
storage device that stores digitally encoded data.
The Input/Ouput Controll Hub (ICH) is an Intel® Southbridge chipset.
Infrared Data Association (IrDA) specify infrared data transmission
protocols used to enable electronic devices to wirelessly communicate
with each other.
The Level 1 Cache (L1 Cache) is a small memory cache built into the
system processor.
The Level 2 Cache (L2 Cache) is an external processor memory cache.
