A conventional wire communication system communicates between powered terminals via a main unit. In this system, the main unit communicates with the powered terminals by changing the voltage signal between positive and negative. The powered terminal communicates with the main unit using the reply current signal. Because this system is used for on-off control, the communication speed is slow. Therefore,...

A conventional wire communication system communicates between powered terminals via the main unit. The DC power of the powered terminal is obtained by rectifying the voltage signal from the main unit. In this system, the main unit communicates with the powered terminal by changing the voltage signal to the positive and the negative. The powered terminal communicates with the main unit using the reply...
In our original wire communication system, an electronic choke is built into each terminal. The electronic choke composed of two small inductors and an amplifier has high input impedance. In the powered terminal, the ac communication signal and the dc power can be separated. To be suitable for the communication frequency use, we should select the inductors of the electronic choke. In the absolute...
