1. Introduction
The W315A/325A 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 W315A and W325A come with an
SD socket, making them the ideal solution when the applications require external storage expansion.
The W315A/325A 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, numerical 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 W315A/325A series embedded computers.

W315A/325A Introduction
1-2
Overview
The W315A/325A 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 a 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 W315A/325A series embedded
computers by using a common compiler, 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.
