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. This chapter covers the following topics:

ThinkCore W341 ThinkCore W311/321/341 Hardware Users 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.

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 users 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. 2-7 ThinkCore W311/321/341 Hardware Users Manual Hardware Introduction Real Time Clock The embedded computers 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. 2-8 33 Chapter 3 Hardware Connection Description ThinkCore W300 Series wireless embedded computers are equipped for multiple types of connections. WLAN, Ethernet, and multiple serial interfaces are built into every model, including a serial console port for monitoring of bootup messages. Select models also include an SD slot for 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. This chapter covers the following topics:

Relay Output (W341 only) ThinkCore W311/321/341 Hardware Users Manual Hardware Connection Description 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:
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.
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.
Keep input wiring and output wiring separate.
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 computers 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. 3-2 ThinkCore W311/321/341 Hardware Users Manual Hardware Connection Description ATTENTION SG V+

12-48V This product should be mounted to a well-grounded mounting surface such as a metal panel. SG: The Shielded Ground (sometimes called Protected Ground) contact is the left most contact of the 3-pin power terminal block connector, as viewed from the angle shown here. Connect the SG wire to an appropriate grounded metal surface. Connecting Data Transmission Cables This section describes how to connect cables for the network, serial devices, and serial COM terminal. Connecting to the Network Plug your network cable into the embedded computers 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 computers 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. 8 8 1 1 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. 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. Pin 1 2 3 4 5 6 7 8 Signal ETx+

Connecting to the WLAN The wireless embedded computer is WLAN ready and includes an 802.11 a/b/g WLAN module. It supports WEP, WPA and WPA2 data encryption. To verify WLAN operation, first configure your WLAN settings on the embedded computer using the serial console or a wired network connection. Please refer to the operating system users manual for further detail. 3-3 ThinkCore W311/321/341 Hardware Users Manual Hardware Connection Description Connecting to a Serial Device Your serial device can plug into the embedded computers serial port using a serial cable. Serial ports P1 to P4 have male DB9 connectors and can be configured for RS-232, RS-422, or RS-485 communication through software. The pin assignments are shown in the following table:
