Introduction

The W315/W325/W345 series of wireless RISC-based embedded computers feature a GSM/GPRS module, RS-232/422/485 serial ports, and an Ethernet port in a small, rugged chassis. In addition, the W325 and W345 models come with an SD slot, and the W345 also has two USB 2.0 hosts and one relay output channel.

The W300 series embedded computers are ideal for diverse, machine-to-machine embedded applications. The computers enable the wireless operation of traditionally wired network and serial devices, and can handle transparent data transfer, 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, we cover the various capabilities of the W300 series embedded computers.

In this chapter, we cover the following topics:

W315/325/W345 Hardware User’s Manual Introduction

Overview

The W315/W325/W345 wireless embedded computers are 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 a significant amount of 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.

An onboard NOR Flash ROM and SDRAM provide ample storage capacity, and the SD slot gives applications extra room to expand. The built-in GSM/GPRS function supports the

850/900/1800/1900 MHz frequency bands, providing coding scheme from CS-1 to CS-4. 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 GPRS network. 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 be ported easily to

W300 series embedded computers by using a common complier, so you do not need to spend a lot of time 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 in the reset button 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 your 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.

Real Time Clock

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 if you need to replace your battery.

Caution

There is a risk of explosion if the battery is replaced by an incorrect type. Dispose of used batteries according to the instructions on the battery.

Wall or Cabinet Mounting

The W315/325/345 embedded computers have built-in “ears” for attaching the embedded computers to a wall or the inside of a cabinet. We suggest using two screws per ear to attach the W315/325/345 to a wall or cabinet. The heads of the screws should be less than 6.0 mm in diameter, and the shafts should be less than

3.5 mm in diameter, as shown by the figure at the right.

W315/325/W345 Hardware User’s Manual Hardware Connection Description

Wiring Requirements

This section describes how to connect serial devices to the embedded computer.

You should read and follow these 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 together with 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 W315/325.

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 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

The PC’s power source should be provided by a UL listed class 2 or “Limited Power Source”

(LPS), with external adaptor output rated 12 to 48 VDC, minimum 1.2A. If the power is supplied properly, 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.

3-3

W315/325/W345 Hardware User’s Manual Hardware Connection Description

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 the W315/325/345 embedded computers to the network, serial devices, and a 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.

Installing a SIM Card and SD Card

Installing a SIM Card

The W315/325/345 embedded computers have a built-in GSM/GPRS cellular module to provide long-range communication. SIM (Subscriber Identity Module) cards are used to authenticate and identify subscribers when connecting to a network.

The SIM card and SD card slot are located on the right side of the W315/325’s casing, and on the front panel of the W345.

Follow these steps to install a SIM card:

Step1: Before you install a SIM card, make sure the embedded computer is powered off.

Step2: Use a screwdriver to remove the protective cover to access the slot. Note that the SD slot and SIM card slot for the W315/W325 share the same protective cover.
