Network connectivity controllers
Factory Automation
The hostile environment of many factories can have a significant impact on the life expectancy of PCs, and industrially hardened PCs can be a very costly alternative. Distributed control systems demand that they not only interconnect a wide variety of equipment – programmable logic controllers, variable speed drives and man machine interfaces for example - but they also communicate with centralized management computers for the purposes of overall supervision, control and data acquisition. Dedicated device networking products meet the challenge.

Added value device networking
Device networking or machine-to-machine messaging has become an essential ingredient in the quest for increased efficiency, optimization and profitability. The maxim is: if there’s a piece of electronic equipment that’s gathering data, then it needs to be networked if it’s to deliver its true worth.
The role of device networking products has as a result become critical to the operation of systems in a wide variety of different sectors.
Factory automation, point-of-sale, building management and very many other systems have all grown to benefit from the adoption of device networking architectures.
The number of device networking products is growing exponentially, bringing with it a positive explosion in the number of connected devices.
The design of device networking products has therefore become a vital concern in the drive for reduced overall system cost, enhanced connectivity and increased performance.

product Retail floor space is a valuable
commodity. Maximizing its revenue generating potential is a key objective.
Reducing the size and cost of PoS stations and connecting them with a back office server are therefore prime concerns, as is the interconnection of a host of RS232 centric peripherals – barcode scanners, displays, cash drawers, printers. PCs are simply too bulky and too expensive for PoS applications, dedicated device networking products provide the best solution.
The ultimate connectivity platform
The breadth and the performance of the connectivity options provided by the OXETHU954 network connectivity controller is simply astounding. And in a world where the microcontroller has become a commodity, it’s the connectivity that makes the difference!
Not only does the chip integrate a 10/100 Ethernet Mac for wired network connections, it also offers a 32-bit / 33MHz PCI interface, enabling wireless network connection via a miniPCI WiFi chip.
What’s more, four of Oxford Semiconductor’s high speed UARTs are also included, providing full modem control and baud rates up to 1Mbaud over RS232, RS422 and RS485 as well as two USB2.0 full-speed host controllers*
capable of operating at up to 12Mbps.
Just consider this amount of high performance connectivity coupled with the incredible resources of the OXETHU954’s embedded ARM9 processor, memory management unit and Linux OS and it’s plain to see just how powerful a connectivity platform this really is.

Device networking
product For the centralization of building
security and environmental control, automated card access has become commonplace. Since buildings are becoming Ethernet cabled, building management systems have tended to rely on Ethernet networking to distribute data and control signals. Key pads, card scanners, CCTV cameras, HVAC plant and lighting circuits - a building’s control devices are however highly diverse in nature and generally offer a simple RS232 communications interface. Interconnecting all such devices at a local level presents a significant challenge. A device networking product provides the answer.
The complete development environment
In getting cutting edge device networking products to market in the shortest possible time, there’s no point wasting time writing communication stacks, developing device drivers or figuring out how to integrate software into a new platform. Design effort is best spent when it’s focused on value added applications rather than ‘me too’ functionality.
That’s why Oxford Semiconductor supports its network connectivity controllers with the most comprehensive and integrated Linux software development kit.
Preconfigured with the Linux operating system, the chip assures users of transparent access to communication stacks, Oxford Semiconductor’s Board Support Package and Root File System and the chip is backed by Eclipse-based IDE tools from Wind River and CodeSourcery.
Selected for its inherent stability and reliability, the Wind River Linux platform is an integral part of the OXETHU954 network connectivity controller. The industry’s premiere commercial- grade develop and run solution, the platform is based on a stable, tested and validated Linux kernel and includes integrated patches and packages for advanced networking, security, and Carrier Grade functionality.
