FIELD: communication equipment. SUBSTANCE: systems for measurement and test of technological equipment in which each signal generator is connected to proper signal receiver through separate cable. Given device is provided with single cable with four electric conductors. Two conductors form line of bus for transmission of signals, two other conductors present power supply line. In proposed device signal generator and each signal receiver have unit controlling bus, preferably, CAN-bus. All signals are transmitted over two-conductor line of bus. Great signal-to-noise ratio exists between transmission of signals and state of rest. Sensitivity to electromagnetic external radiation is also extremely insignificant. EFFECT: reduced number of connecting cables. 4 cl, 1 dwg
