cable assembly to access fieldbus data on rolling stock

摘要

a cable assembly (1) to provide a data acquisition system (2) with data messages (300) passing on a field bus (3) of the rolling stock (10), said cable assembly (1) comprising: - a data interceptor (101) adapted to intercept said data messages (300) passing on said field bus (3); - a data transmitter (102) adapted to transmit said data messages (300) to said data acquisition system (2); and - an isolation module (103) adapted to electrically isolate said data transmitter (102) from said data interceptor (101) and said fieldbus (3), thereby electrically isolating said data acquisition system (2) of said fieldbus (3) so that said data acquisition system (2) is limited by said isolation module (103) to only intercept said data messages (300) passing on said bus field (3).
