ThinkCore W341/321/311 Hardware User’s Manual Hardware Introduction 1-3Overview 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.

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
ThinkCore W341/321/311 Hardware User’s Manual Hardware Introduction 2-13recommend 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.

33 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 Requirement  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.
UC-7112/7110 User’s Manual UC Finder 3-2 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. V+V-SG12-48V SG: The Shielded Ground (sometimes called Protected Ground) contact is the left most contact of the 3-pin power terminal block connector when 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 ThinkCore W341/321/311 to the network, serial devices,
UC-7112/7110 User’s Manual UC Finder 3-3and 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. 18 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.
