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.

ThinkCore W311/321/341 Hardware User’s 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: 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. 3-2

ThinkCore W311/321/341 Hardware User’s Manual Hardware Connection Description ATTENTION This product should be mounted to a well-grounded mounting surface such as a metal panel. SG 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. V- V+ 12-48V 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 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. 8 1 The LED indicator in the lower right corner glows a solid green color when the cable is properly Pin Signal connected to a 100 Mbps Ethernet network.
