The ThinkCore W300 Series is a line of wireless RISC-based embedded computers that feature
802.11a/b/g WLAN, RS-232/422/485 serial ports, and an Ethernet port in a small, rugged chassis.
In addition, the W321 and W341 models feature an SD slot, and the W341 features two USB 2.0
hosts and one relay output channel.
As part of the W300 Series, your embedded computer is ideal for diverse, machine-to-machine
embedded applications. It enables wireless operation of traditionally wired network and serial
devices and not only provides transparent data transfer, but also 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, learn about the
capabilities of the embedded computer.

ThinkCore W311/321/341 Hardware User’s Manual                                              Introduction


Overview
         The ThinkCore W300 Series wireless embedded computer is 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 significant 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.
         On-board NOR Flash ROM and SDRAM provides ample storage capacity, and for select models,
         the SD slot gives applications extra room to expand. The built-in WLAN function supports the
         802.11a/b/g standard, providing transmission security with WEP, WPA and WPA2. 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 WLAN. 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 easily be ported to
         W300 Series embedded computers by using a common complier, so little time is spent 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 the reset button down 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 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.

         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 for battery
         replacement.

Wiring Requirements
         This section describes how to connect serial devices to the embedded computer.
         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 installation and/or wiring.
         Watch Electrical Current!
         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.
         Watch Temperature!
         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
         Connect the “live-wire” end of the 12-48 VDC power adapter to the embedded computer’s
         terminal block. When power is properly supplied, 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.
