Abstract: A device configured to process data comprised in data messages passing on message buses of a rolling stock comprises: a universal input interface receiving data messages complying with the three following physical layers: RS232; RS485; CAN. From the message buses, the data messages comprise data; a processing engine receiving a remote requested configuration comprising one or more processing rules; a standardizing unit decoding the data messages into standardized data streams in function of the remote requested configuration; and wherein the processing engine further applies one or more of the one or more processing rules of the standardized data streams in function of the remote requested configuration.

Abstract: A cable assembly for providing a data acquisition system with data messages passing on a fieldbus of rolling stock, said cable assembly comprising a data listener adapted to listen in on said data messages passing on said fieldbus; a data transmitter adapted to transmit said data messages to said data acquisition system; and an isolation module adapted to electrically isolate said data transmitter from said data listener and from said fieldbus, thereby electrically isolating said data acquisition system from said fieldbus such that said data acquisition system is limited by said isolation module to only listening in on said data messages passing on said fieldbus.
