Overview

The W315A/325A are embedded Linux computers that feature 1 or 2 software selectable RS-232/422/485 ports, 1 Ethernet port, and quad-band GSM/GPRS 850/900/1800/1900 MHz for cellular communication. Both the W315A and W325A come with an SD socket for external storage expansion. The W315A/325A computers’ Linux OS runs on the MOXA ART 32-bit ARM9 processor, which provides a powerful and reliable platform for harsh, industrial environments. You will find these computers ideal for a variety of machine-to-machine applications, including data acquisition, protocol conversion, and remote device control and monitoring.

 

The W315A and W325A, which are upgrades of the W315 and W325, provide the following benefits not provided by the W315 and W325:


1. Users can execute commands while GPRS is connected
2. Application program development is much easier using the Rcore package

White Paper

Building the Industrial Cloud:The Immediate Future of M2M Technology

 

Building the Industrial Cloud:The Immediate Future of M2M TechnologyIn 2013, substantial steps towards building the Internet of Things at last began to materialize. In this white paper, Moxa examines the sorts of technology industrial networks will be relying on as they begin to build and deploy machine-to-machine networks. Software automations, hardware optimizations, and integrated platforms that fully exploit the convergence of these two main branches of system design are examined closely, to give IA and IT engineers a better idea of what challenges and obstacles they should be preparing for at the dawn of this new technological epoch........more
