FIELD: electrical engineering.
SUBSTANCE: invention relates to combined power supply and data transfer between data server 4 and at least one of several terminals 5, 6 via feed cable. In particular this invention may be used at aircraft. Data server 4 and each of several terminals 5, 6 are connected via I/O device 7, 8, 9 with feed cable 3 while the latter comprises at least four conductors 3a-3d. note here that at least two conductors corresponds to data transfer in upward direction while two other conductors corresponds to channel of downward data transfer.
EFFECT: optimum power supply of aircraft loads and data transfer, reduced costs.
