Chapter 1 Introduction
The W406 is an embedded Linux or WinCE computer that features 2 software selectable
RS-232/422/485 ports, 1 Ethernet port, and quad-band GSM/GPRS/EDGE 900/1800/850/1900
MHz for cellular communication. It also comes with an SD socket, USB host, and 4 digital input
and 4 digital output channels, making it the ideal computer for a variety of industrial applications
such as data acquisition, data processing, protocol conversion, and remote device control and
monitoring via wireless communication.
The W406 comes pre-installed with either Linux or WinCE 6.0, and offers a reliable and powerful
computing platform for industrial environments. Programmers will find the W406 to be an easy
platform to develop programming environments for producing bug-free industrial applications at a
lower cost.

W406 Hardware User’s Manual Introduction
Overview
The W406 wireless embedded computers are designed around the Cirrus Logic EP9302 ARM9
32-bit RISC processor. Unlike the X86 CPU, which uses a CISC design, the Cirrus Logic EP9302
ARM9 uses RISC architecture and modern semiconductor technology to provide a powerful
computing engine without generating a significant amount of heat. The processor also integrates
UART and LAN functions to provide exceptional communication performance, but without the
bus bandwidth limitations associated with general ARM-based communication products.
An onboard NOR Flash ROM and SDRAM provide ample storage capacity, and the SD slot gives
applications extra room to expand. The built-in GSM/GPRS/EDGE function supports the
850/900/1800/1900 MHz frequency bands, providing coding scheme from CS-1 to CS-4. The
backup LAN port not only provides an alternative solution for networking, but also supports
Ethernet clients, allowing any network device to plug in and connect to the GPRS/EDGE network.
The built-in RS-232/422/485 serial ports support a wide range of serial devices, making this
platform suitable for data acquisition and protocol conversion applications.
The Linux or WinCE 6.0 operating system comes pre-installed and ready to run, providing an
open platform for software development. Software written for desktop PCs can be ported easily to
W406 series embedded computers by using a common complier, so you do not need to spend a lot
of time modifying existing software code. In addition, the operating system, device drivers, and
user-developed software can all be stored in the built-in flash memory.

Reset Button
Hold in the Reset to Default button for 5 seconds to load the factory default configuration. After
loading the factory defaults, the system will reboot automatically. We recommend that you use this
function only if the software is not working properly. To reset the Linux system software, always
use the software reboot command (“reboot”) to protect the integrity of your data.
The reset button is NOT designed as a hard reboot for the embedded computer.
ATTENTION
Restoring default settings preserves your data
Resetting the embedded computer to factory defaults will NOT format the user directory and will
NOT erase the user’s data. The reset button only loads a configuration file. All files in the /etc
directory will revert to their factory defaults, but all other user data will remain intact in the Flash
ROM.
Please note that if there is a problem with the /etc directory, the embedded computer may be
unable to restore the factory default settings.

W406 Hardware User’s Manual Hardware Introduction
Real Time Clock
The embedded computer’s real-time clock is powered by a lithium battery. We strongly
recommend that you NOT replace the lithium battery on your own. If the battery needs to be
changed, please contact the Moxa RMA service team.
ATTENTION
There is a risk of explosion if the wrong type of battery is used. To avoid this potential danger,
always be sure to use the correct type of battery. Contact the Moxa RMA service team if you
need to replace your battery.
Caution
There is a risk of explosion if the battery is replaced by an incorrect type. Dispose of used
batteries according to the instructions on the battery.

Wiring Requirements
This section describes how to connect serial devices to the embedded computer.
You should read and follow these common safety precautions before proceeding with the
installation of any electronic device:
yUse separate paths to route wiring for power and devices. If power wiring and device wiring
paths must cross, make sure the wires are perpendicular at the intersection point.
NOTE: Do not run signal or communication wiring together with power wiring in the same
wire conduit. To avoid interference, wires with different signal characteristics should be routed
separately.
yUse the type of signal transmitted through a wire to determine which wires should be kept
separate. The rule of thumb is that wiring that shares similar electrical characteristics can be
bundled together.
yKeep input wiring and output wiring separate.
yIt is advisable to label the wiring to all devices in the system.
ATTENTION
Safety First!
Be sure to disconnect the power cord before installing and/or wiring your W406.
Wiring Caution!
Calculate the maximum possible current in each power wire and common wire. Observe all
electrical codes dictating the maximum current allowable for each wire size.
If the current goes above the maximum ratings, the wiring could overheat, causing serious
damage to your equipment.
Temperature Caution!
Be careful when handling the unit. When the unit is plugged in, the internal components generate
heat, and consequently the outer casing may feel hot to the touch.
Connecting the Power
The PC’s power source should be provided by a UL listed class 2 or “Limited Power Source”
(LPS), with external adaptor output rated 12 to 48 VDC, 1200 mA @ 12 VDC, 580 mA @ 48
VDC. If the power is supplied properly, the “Ready” LED will glow a solid green after a 25 to 30
second delay.
Grounding the Unit
Grounding and wire routing help limit the effects of noise due to electromagnetic interference
(EMI). Before connecting any devices, run a ground wire from the ground screw to the grounding
surface.

SG: The Shielded Ground (sometimes called
Protected Ground) contact is the bottom contact of

Connecting Data Transmission Cables
This section describes how to connect the W406 embedded computers to the network, serial
devices, and a serial COM terminal.
Connecting to the Network
Plug your network cable into the embedded computer’s Ethernet port. The other end of the cable
should be plugged into your Ethernet network. When the cable is properly connected, the LEDs on
the embedded computer’s Ethernet port will glow to indicate a valid connection.
The 10/100 Mbps Ethernet LAN port uses 8-pin RJ45 connectors. The following diagram shows
the pinouts for these ports.
The LED indicator on the left bottom corner glows a solid
green color when the cable is properly connected to a 100
Mbps Ethernet network. The LED will flash on and off
when Ethernet packets are being transmitted or received.
