How To Create Your Own Switching System
Dow-Key Microwave is pleased to release three new application notes describing how one can build one's own switching system by using Dow-Key CANBus switches together with an ENET or a GPIB kit. The difference between the ENET kit and the GPIB kit lies in that the translator board uses either the TCP/IP protocol or the GPIB protocol respectively to transmit data.

| Featured Article | | Proprietary Wireless – For Those Times When Standards Aren't Best
By Nick Hunn, Laird Technologies
Today when most designers decide they need to cut the cable and add wireless links to their products the first thing they think of is the well-known wireless standards – typically Bluetooth, Wi-Fi or ZigBee. In many cases that may be the valid choice, but it means that the advantages of proprietary wireless can be overlooked. This article explains the differences and highlights the times when designers should consider proprietary RF as a valid option for their products...
