Chapter 1 Introduction
The ThinkCore W315/W325/W345 series of wireless RISC-based embedded computers feature a
GSM/GPRS module, RS-232/422/485 serial ports, and an Ethernet port in a small, rugged chassis.
In addition, the W325 and W345 models come with an SD slot, and the W345 also has two USB
2.0 hosts and one relay output channel.
The W300 series embedded computers are ideal for diverse, machine-to-machine embedded
applications. The computers enable the wireless operation of traditionally wired network and serial
devices, and can handle transparent data transfer, numeric computing, protocol conversion, data
processing, and even data encryption. You will find it easier to build embedded systems for
distributed peer-to-peer communication, turn wired devices into wireless devices, and introduce
higher mobility and more intelligence to your system. In this chapter, we cover the various
capabilities of the W300 series embedded computers.
In this chapter, we cover the following topics:

ThinkCore W315/325/W345 Hardware User’s Manual Introduction
Overview
The ThinkCore W315/W325/W345 wireless embedded computers are designed around the MOXA
ART ARM9 32-bit RISC processor. Unlike the X86 CPU, which uses a CISC design, the MOXA
ART 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 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 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-based 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
W300 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 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.

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.

Chapter 3 Hardware Connection Description
The ThinkCore W300 series wireless embedded computers support multiple types of connections.
GSM/GPRS, Ethernet, and one or more serial ports are built into every model. In addition, the
computers come with a serial console port for monitoring bootup messages. All models include an
SD storage expansion, USB ports for additional device and storage options, and relay output
connections. With the open-source Linux kernel, you are free to develop custom applications for
remote, wireless operation of your device. In this chapter, learn how to connect the embedded
computer to the network and to various devices.
In this chapter, we cover the following topics:

Wall or Cabinet Mounting
The ThinkCore W315/325/345 embedded computers have built-in “ears” for
attaching the embedded computers to a wall or the inside of a cabinet. We suggest
using two screws per ear to attach the W315/325/345 to a wall or cabinet. The
heads of the screws should be less than 6.0 mm in diameter, and the shafts should
be less than 3.5 mm in diameter, as shown by the figure at the right.

ThinkCore W315/325/W345 Hardware User’s Manual Hardware Connection Description
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:
y Use 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.
y Use 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.
y Keep input wiring and output wiring separate.
y It 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 W315/325.
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, minimum 1.2A. 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 left most contact

Connecting Data Transmission Cables
This section describes how to connect the W315/325/345 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 in the lower right 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.
