Overview

The UC-8481 embedded computer comes with 2 RS-232/422/485 serial ports, 2 Ethernet ports, 4 digital input channels, 4 digital output channels, a CompactFlash socket, and 2 USB 2.0 ports.

 

The computer uses the Intel XScale IXP435 533 MHz RISC CPU. This powerful computing engine supports several useful communication functions, but will not generate too much heat. The built-in 32 MB NOR Flash ROM and 512 MB SDRAM give you enough memory to run your application software directly on the UC-8481, and the 512 MB NAND Flash can be used to provide additional data storage.

 

Mostly importantly, the UC-8481 series comes with seven connectors that allow users to connect various wireless and GPS modules, making it particularly well-suited for rolling stock and moving vehicles. The UC-8481 is a convenient cornerstone for customizing intelligent, cost-effective wireless communication platforms.

 

With an embedded Linux operating system pre-installed, the UC-8481 series provides an open software platform perfect for custom-authored software. Software written on desktop PCs can be easily ported to the UC-8481 via a common compiler, without any modification of code. This makes the UC-8481 an optimal solution for industrial applications, allowing ample customization with minimal cost and effort.

 

In addition, the UC-8481 comes in a wide-temperature model designed to operate reliably in extremes from -25° to 70° C.

Securing Edge Devices and Data in Distributed Industrial Applications

 

Securing Edge Devices and Data in Distributed Computing Application White PaperIn this white paper, Moxa examines the unique security challenges posed by widely distributed computing solutions that put edge devices into residential homes and public spaces. When considering computers for smart grid, surveillance, and ITS solutions, system integrators must also consider how to lock down the hardware and software to protect the devices from being subverted by hostile exploits. End users and system integrators alike will find that the Trusted Computing Platforms figures strongly in the solution, and when combined with secure kernel authentication and a variety of other software and hardware features produces a powerful, versatile computing solution with a wide range of applications.........more

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
