How does a computer monitor be connected to a satellite antenna? What adapter is needed? Still need more high-end things to connect? And shows how much money you need to buy something Please! Question added: Is the monitor connected to the day pot set-top box? Not a closed route! More
Buy a set-top box on the line if you are now buy a monitor to buy a TV on the line
Communication cable not only voltage, current, resistance, a parameter requirements, but also the characteristics of impedance, attenuation and other secondary parameters, therefore, the cable is more sophisticated Most of the control cable transmission switch, low-speed analog signal to meet the Ohm's law is the main premise, and no secondary parameters, relative to the communication cable, the conductor is relatively thick, the structure is simple
I have to help you answer: Automatic control cable: refers to the automation control signal class cable, generally multi-strand copper core cord, mainly for the transmission signal, the cross-section is small, mostly 0.25 to 1 square millimeters of small lines, 10 Ranging from hundreds of cores; control cable: refers to the transmission control signal class cable, generally multi-core hard wire, transmission control signal is generally 1.5 to 2.5 square millimeters, the transmission voltage signal is generally 2.5 ~ 4 square mm cable, Current signal is generally more 4 to 6 square millimeters cable, 4 to 36 core, and then the number of cores is relatively rare Power cable: that is, we often say that the power cable, transmission of hard copper or aluminum cable, 1 to 5 Core cross-section 16 to 600 square millimeters have.

Factory communication line dedicated cable is used to transmit two-way signal, the control cable is used to transmit one-way signal (with feedback circuit is still regarded as the control circuit)
