ThinkCore W341/321/311 Hardware User’s Manual Hardware Introduction

Overview

ThinkCore W300 Series use the MOXA ART ARM9 32-bit RISC processor. Unlike the X86 CPU,
which uses a CISC design, the ARM9’s RISC design architecture and modern semiconductor
technology provide ThinkCore W341/321/311 with a powerful computing engine, but without
generating too much heat. In addition to the ARM9 core, the MOXA ART ARM9 processor
integrates UART and LAN functions, provide the extreme communication performance without
the bus bandwidth limitation as general ARM-based communication products.

Moreover, the on-board NOR Flash ROM and SDRAM give you enough storage capacity and the
additional SD socket provide the flexible storage expansion to run applications. The built-in
WLAN function supports the popular 802.11a/b/g standard, provide the transmission security
including WEP, WPA and WPA2. The backup LAN port not only provides the alternative solution
on networking but also supports the Ethernet Client capability, to make the network device to be
hooked on WLAN by easily plug-in step. Besides, the RS-232/422/485 serial ports allow you to
connect a variety of different types of serial device, make this communication platform suitable for
some of the more simple data acquisition and protocol conversion applications.

The pre-installed ready-to-run Linux-based operating system provides an open software operating
system for software program development. This means that software written for desktop PCs is
easily ported to ThinkCore W341/321/311 by using a common complier, so that you will not need
to spend time modifying existing software code. The Operating System, device drivers, and your
own software can all be stored in ThinkCore W300’s Flash memory.

Reset Button

Press the “RESET” button continuously for more than 5 seconds to load the factory default
configuration. After loading the factory defaults, the system will reboot automatically. The System
Ready LED will blink for the first 5 seconds. We recommend that you only use this function 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 data that is in the process of being transmitted.
The reset button is NOT designed to Hard Reboot ThinkCore W300 Series products.

ATTENTION

Reset to Default preserves user’s data

Resetting to factory defaults will NOT format the user directory and erase the user’s data. Pressing
this Reset button will only load the configuration file. All files in the /etc directory will revert to
their factory defaults, but other User Data will still exist in the Flash ROM.

This function only takes effect when the user directory is working correctly. If the user directory
has crashed, the kernel will automatically load the factory defaults.

Real Time Clock

ThinkCore W341/321/311’s real time clock is powered by a lithium battery. We strongly

2-12

ThinkCore W341/321/311 Hardware User’s Manual Hardware Introduction

recommend that you do not replace the lithium battery without the help of MOXA’s support team.
If the battery needs to be changed, contact the MOXA RMA service team for RMA service.

ATTENTION

The battery may explode if replaced by an incorrect type. To avoid this potential danger, always be
sure to use the correct type of battery.

Chapter 3 Hardware Connection Description

This chapter describes how to connect ThinkCore W341/321/311 hardware, includes information
about the power connecting, wiring and function introduction.

This chapter covers the following topics:

 Wiring Req u irement
 Connecting the Power
 Grounding ThinkCore W341/321/311
 Connecting to the Network
 Connecting to a Serial Device
 Connecting to the Console Port
 Internal SD Socket
 USB Hosts
 Relay Output

Wiring Requirements

This section describes how to connect ThinkCore W341/321/311 to serial devices.

You should heed the following 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 and 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 ThinkCore

W341/321/311.
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 ThinkCore W341/321/311. When plugged in, ThinkCore

W341/321/311’s internal components generate heat, and consequently the outer casing may feel
hot to the touch.

Connecting the Power

Connect the “live-wire” end of the 12-48 VDC power adapter to ThinkCore W341/321/311’s
terminal block. If the power is properly supplied, the “Ready” LED will glow a solid green after a
25 to 30 second delay.

Grounding W341/321/311

Grounding and wire routing help limit the effects of noise due to electromagnetic interference
(EMI). Run the ground wire from the ground screw to the grounding surface prior to connecting
devices.

ATTENTION

This product should be mounted to a well-grounded mounting surface such as a metal panel.

Connecting Data Transmission Cables

This section describes how to connect ThinkCore W341/321/311 to the network, serial devices,

3-2

UC-7112/7110 User’s Manual UC Finder

and serial COM terminal.

Connecting to the Network

Connect one end of the Ethernet cable to ThinkCore W341/321/311’s 10/100M Ethernet port and
the other end of the cable to the Ethernet network. If the cable is properly connected, ThinkCore
W341/321/311 will indicate a valid connection to the Ethernet in the following ways:

y The top-right LED on the connector glows a solid green when connected to a 100 Mbps

Ethernet network.

y The top-left LED on the connector glows a solid orange when connected to a 10 Mbps

Ethernet network.

y The LEDs will flash when Ethernet packets are being transmitted or received.

The 10/100 Mbps Ethernet LAN port use 8-pin RJ45 connectors. Pinouts for these ports are given
in the following diagram.

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.

18

The LED indicator in the lower left corner glows a
solid orange color when the cable is properly
connected to a 10 Mbps Ethernet network. The
LED will flash on and off when Ethernet packets
are being transmitted or received.

Connecting to the WLAN

ThinkCore W341/321/311 is the WLAN ready wireless embedded computer, embeds an 802.11
a/b/g WLAN module inside and support the WEP, WPA and WPA2 data encryption. To make sure
the WLAN function works normally, please enter the system first to do the associated WLAN
configuration via fixed network or serial console, you may refer to the OS operating user’s manual
for the further detail.

Connecting to a Serial Device

Connect the serial cable between ThinkCore W341/321/311 and the serial device(s).

Serial ports P1 to P4 use male DB9 connectors, and can be configured for RS-232/422/485 by
software. The pin assignments are shown in the following table:
