Multiplexed communication network e.g. vehicle area network, for use in e.g. airplane, has secondary connector that is coupled to external equipment for analyzing and/or non-intrusively testing operation of bus and/or communicating body

摘要

The network (RB) has a bus (BU1) that is connected to a primary branch input/output (BP12). A primary connector (CP) is utilized for connecting to a communicating electronic body (O12). A secondary branch input/output (BS) is provided with an end that is connected to the bus. Another end of the secondary branch input/output is connected with a secondary connector (CS). The secondary connector is coupled to an external equipment (EA) e.g. dedicated portable computer, for analyzing and/or non-intrusively testing an operation of the bus and/or the communicating electronic body.
