1. A method for communicating data between a plurality of communication equipments present on an on-board device, the communication equipments being connected to at least one pair of communication conductors,
wherein
each communication equipment, when activated, is by default in a receiving mode, in which it is able to receive at least one data frame on the pair of communication conductors and is able to be put in an emission mode, in which it emits a data frame on the pair of communication conductors,
each communication equipment has at least one incremental identification, which is a determined real value, the incremental identifications being different from each other,
at least one of the communication equipments, called first communication equipment is activated and put into the emission mode, during which the first communication equipment emits on the pair of communication conductors the data frame containing the incremental identification of the first communication equipment, called first data frame, while each communication equipment, other than the first communication equipment, called second communication equipment, is activated and put into receiving mode, then the first communication equipment is put into receiving mode,
each second communication equipment, prescribes its local emission time window, which is associated with its incremental identification, during which the second communication equipment is put into emission mode for its data frame,
a time of beginning of the local emission time window of each second communication equipment being a determined function, increasing with respect to a difference equal to the incremental identification of the second communication equipment from which is subtracted the incremental identification of the first communication equipment, contained in the first data frame,
the local emission time windows being disjoint,
each second communication equipment is put, for its incremental identification, into emission mode during which the second communication equipment emits on the pair of communication conductors its data frame, containing the incremental identification of the second communication equipment, during its local emission time window starting at the time of beginning of this local emission time window.
