Modular DIN Rail Box PC Targets Transportation Systems

MEN Micro has announced the MC50M, a modular DIN rail box PC for embedded applications in transportation. The computer platform is based on Intel’s Atom E3900 CPU series. This makes the MC50M the ideal basis for functions such as security gateway, predictive maintenance, CCTV, ticketing systems or as a diagnostic server.

The MC50M can be used as a stand-alone product or in combination with a range of pre-fabricated extension modules, providing additional features and short delivery times. Extension modules can provide application-specific functions such as wireless communication (LTE advanced, WLAN, GNSS), MVB, CAN bus or other I/Os. A removable storage shuttle supports the integration of one to two 2.5″ SATA hard disks/SSDs. The wide range PSU allows isolated power supply from 24 V DC to 110 V DC nominal and extends the entire system to EN 50155 compliance.

The board management controller provides increased reliability and reduces downtime. The Trusted Platform Module supports security and encryption features. With the ignition switch for remote startup and shutdown control, the platform provides additional energy saving features. The aluminum housing with cooling fins ensures conductive cooling and fanless operation. The MC50M has no moving parts, so it can be operated maintenance-free.

The long-term availability of 15 years from product launch minimizes life cycle management by making the MC50M available for at least this period. MEN’s DIN rail concept is designed for flexible configuration of module combinations and is suitable for embedded IoT applications in various markets. The CPU modules can be flexibly combined with various expansion modules and power supplies.

In the modular system, the data transfer between the individual modules as well as the power supply of the components is implemented via the expansion connectors standardized by MEN.The concept specifications include housing dimensions, mounting, cooling and IP protection. In addition, the expansion connectors and their pin assignment are defined. DIN rail mounting (35 mm) is standard. Wall and 19” rack mounting is possible using adaption brackets.

WLAN Measurement Suite Solution for 802.11ax High-Efficiency Wireless

National Instruments (NI) recently announced an early access version of the WLAN Measurement Suite with support for the IEEE 802.11ax (draft 0.1) high-efficiency wireless draft standard. Combined with NI’s RF vector signal transceiver (VST), the WLAN Measurement Suite enables you to measure the performance of their 802.11ax designs confidently in the presence of significant new changes to the 802.11 physical layer specification.National Inst WLAN MeasSuite

Aso called High-Efficiency Wireless (HEW), the 802.11ax is intended to improve the average throughput per user by a factor of at least 4× in dense user environments. This new standard focuses on implementing mechanisms to serve more users a consistent and reliable stream of data (average throughput) in the presence of many other users.

The WLAN Measurement Suite offers the power and flexibility to generate and analyze a wide range of 802.11 waveforms, such as 802.11a/b/g/n/j/p/ac/ah/af. Now, with the measurement suite’s latest update targeting 802.11ax, you can speed up development work on 802.11ax devices. The software supports key features of 802.11ax, including narrower subcarrier spacing, 1024-QAM, and multi-user orthogonal frequency division multiple access (OFDMA). The updated measurement suite also includes LabVIEW system design software example code to help engineers automate WLAN measurements quickly and easily.

NI’s platform-based approach helps ensure you can update their existing PXI RF test systems to support 802.11ax device testing with a simple software update and continue to do so as the 802.11ax standardization process evolves. You can take advantage of this smarter approach to RF test to help lower the cost of testing and better prepare for future connectivity and cellular standardization initiatives, such as 5G.

New Home Control & IoT Wi-Fi Module

MSC Technologies, a business group of Avnet Electronics, recently introduced the new WLAN-Module HDG820 for 802.11.b/g/n networks, designed by H&D Wireless AB (Sweden). The solution incorporates a complete IP protocol set running on an internal ARM Cortex core and is an ideal platform for advanced smart-home, IoT and M2M applications over Wi-Fi.MSC-H-and-D-WirelessWeb

H&D Wireless AB specializes in world class Wi-Fi solutions, combining a deep knowledge of embedded wireless systems, silicon design and system software for cloud services and mobile phone apps. The company’s range of WLAN is deemed best in class in terms of size, power consumption in all modes, transmit/receive range, data transfer speed and cost. Wi-Fi solutions from H&D Wireless are supported on leading MCU platforms allowing easy access to the Internet as well as data and audio for consumer electronics.

The new HDG820 SiP-Module from H&D Wireless includes the Controller, WLAN transceiver and Memory and is delivered in an extremely small SMD package of 8 × 8 × 1.2 mm3. It can be controlled via UART / SPI which is also the interface for data transfer. With a power consumption of max. 220 mA and 250 µA in Sleep mode and an RF performance of +17 dBm in Tx and –96 dBm in Rx, it fulfills all requirements for typical building and home applications. An extended temperature of –40 to +85°C also makes it an ideal platform for Wi-Fi enabled sensors in industrial applications.

The HDG820 module is pre-certified for CE and FCC and of course Wi-Fi certified. In addition to its compact size only very few components need to be added to the BOM list (e.g., antenna and capacitors), allowing for extremely competitive new designs with all the benefits of WLAN solutions.

Even more interesting is the list of supported software features. Protocols like TCP/IP, HTTP and more as well as features like Soft-Access Point, Wi-Fi Direct and also security features like WPA are available and fully integrated. The Pico oWL API is designed to be compiled and executed on multiple processor platforms from 8 bit to 32bit and makes configuration really easy, also enabling full control of the module. H&D Wireless even supplies a Linux design environment.

Furthermore the Griffin Software, also delivered by H&D Wireless, supports full cloud computing capabilities and easy app integration with several reference designs available. All software is available for free. Development kits, demo applications and of course the modules itself are available at MSC Technologies in Europe and Avnet Electronics worldwide.
