DiSEqC is Digital Satellite Equipment Control in English, which is literally translated as “Digital Satellite Equipment Control”. It is controlled by a digital satellite TV receiver and issues an instruction set (control instruction) to the corresponding equipment, such as switches, antenna drive equipment, LNB, etc. . DiSEqC only is a control protocol, not hardware and there are different versions.
The working process is that under the coordination of synchronous clock pulses inside the digital satellite TV receiver, through the coaxial cable connected to the LNB, the digital signal modulated at the frequency of 22KHz alternately transmits the relevant control commands serially.
