Villepreux, France The RD320-OF serial RS232/422/485 to single mode fiber optic media converter from Acksys allows to easily and quickly connect industrial serial links to the long distance optic fiber network. Using optic fiber enables to use an higher bandwidth while keeping safe from EMI/RFI interferences for increased security. The optical fiber still offers other advantages : use without risk in an explosive environment, no EMC emission, no ground loops, and immunity against lightning and high voltage environments. They are finally lighter, less cumbersome, inert and corrosion resistant. The RD320-OF is Plug & Play, and features an original mechanism of self configuration (CPLD) which frees users from tiresome serial parameters setup. Moreover, the equipment features a security system which controls the fiber and signals any breakdown via a LED while activating a relay contact in order to connect any external safety system. The RD320-OF is designed to match point to point and ring topologies. It is MODBUS, UNITELWAY, PROFIBUS, DH+ compatible, as well as with any other ASCII or binary serial protocols. It supports a speed of 500 Kbps. Acksys Communication Systems , Villepreux, France. www.acksys.fr.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
