FIELD: information technology.
SUBSTANCE: method for contactless data reading is based on recording voltage generated by electromagnetic fields of pair of communication bus (CB) wires (1), over which the read-out differential information signal (DIS) is transmitted, when the mentioned recording is performed by contactless capacitive sensor (CS) (4) with two armatures located near CB wires (1), with amplifying analog signal obtained at the output of CS (4) and consequent conversion of amplified signal into information signal characterising the read-out DIS. In this process of data reading from CB (1), separate impact of electromagnetic fields of CB (1) wires pair on CS (4) armatures is provided, wherefore each wire of wires pair of CB (1) and located near it CS (4) armature is isolated from other wire and located near its second CS (4) armature by grounded electroconductive shield.
EFFECT: higher reliability of data reading, functionality enhancement and simplification of adapter design while lowering its materials consumption, dimensions and cost.
