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.
The UC-8481 also comes in a wide-temperature model designed to operate reliably in extreme temperatures ranging from -25 to 70°C.

Building a Future-Proof Data Processing Solution with Intelligent IoT Gateways
To date, most discussions about the
Industrial Internet of Things (IoT) have been about connecting new devices and rapidly bringing them online. In this white paper we look at the implications of bringing such a large number of devices online, namely, the need for efficient methods to collect information from these devices, and discuss how to handle the large amount of data collected from these devices.
Industrial IoT solutions are judged on their ability to adapt to various data acquisition needs and how they can transform the data collected from devices into useful business insights that can help decision makers. What makes an Industrial IoT solution truly stand out is the flexible data handling possibilities that it can provide………..more

Developing a Data Acquisition Platform for Industrial IoT Applications
The impact the Internet has had on the way humans live their .jpg)
lives has been unprecedented. It has allowed us to communicate and interact with each other in ways previously unimaginable. Recently, it has opened the door for what many are describing as something that will become more important to our everyday lives than the Internet, the Internet of Things (IoT). One of the most exciting possibilities is in industrial applications, more commonly referred to as the Industrial Internet of Things (Industrial IoT), where communication and interaction capabilities can be extended to devices or things used for factory automation, renewable energy applications, smart grids, intelligent transportation systems, and even oil and gas applications……….more
