FIELD: physics.
SUBSTANCE: socket of connecting cable with the data unit of connection is equipped with radio-frequency score (RFID) in monitoring system which changes reciprocal signal perceived by radio-frequency input reader, unique fashion when socket is connected to the port equipped with the modulator, serving for unique change of reciprocal signal of score; identify socket and port having the socket connected, on the basis of reciprocal radiation radio-frequency score (RFID), changed by unique fashion. The radio-frequency score can contain a reed relay, included in contour of its antenna, and the modulator to be an electromagnet.
EFFECT: possibility to increase monitoring of detachable joints using only one antenna of the radio-frequency input reader on a group of ports.
