Abstract
A device is provided for interconnecting a series of data acquisition apparatuses. Each of the apparatuses collect signals and transmit them to a remote central receiving and recording system. In order to sequentially transmit the signals thereto on reception of an order from said central system, the apparatuses are subdivided into a plurality of groups having the same number m of apparatuses. The groups comprise cable sections of substantially equal length interconnecting the acquisition apparatuses in such a manner that the apparatuses of the same rank of each group are connected in parallel by the same transmission cable to the central system.
