A high speed fibre communication link for measurement & I/O (M&IO-Net)

A new concept of analogic and digital signal transportation, 'M&IO-Net', mainly dedicated to the acquisition system has been developed at Tore Supra to simplify infrastructures of wiring and to guarantee the measurements and the transportation of signals in the best possible conditions. The structure of the system M&IO-Net leans on high speed optical fiber link. Protocols of communication are very simple and allow the easy development of a large range of acquisition cards. Two generations of this system coexist. The first is specifically dedicated for acquisition of data. The second, more rapid and structured in a network ring, possesses read and write capacities, interesting for the acquisition of data but also for the control of the local acquisition unit and the copy of signals between distant sites.
