The principle of serial communication of DC regulated power supply
Release time:
2023-09-06
With the development of science and technology, we have a higher demand for electronic products, so we need a convenient, flexible and reasonably priced power supply for electronic products. Dc power supply manufacturer DC power supply is controlled by microcomputer, advanced technology, simple operation, small size, light weight. Because of these characteristics, it is loved by many consumers, but what you may not know is the communication principle of DC regulated power serial port.
With the development of science and technology, we have a higher demand for electronic products, so we need a convenient, flexible and reasonably priced power supply for electronic products. Dc power supply manufacturer DC power supply is controlled by microcomputer, advanced technology, simple operation, small size, light weight. Because of these characteristics, it is loved by many consumers, but what you may not know is the communication principle of DC regulated power serial port.
At present, the DC regulated power supply produced by the DC regulated power supply manufacturer has two communication interfaces, one is used to communicate with the upper computer and the touch screen, and the other is used to download the program. The other is responsible for building the network and controlling the communication. In the communication of programmable DC power supply, data will be transmitted between the two stations, and then the data shows that the communication line is divided into simplex transmission, half-duplex transmission, full-duplex transmission three ways. Simplex communication generally uses a line, the signal has a clear direction, and the communication only goes in one direction.
One wire is used for sending and receiving at the same time, and data can be transmitted in both directions, but not simultaneously, so this is called half duplex. When working, the transmitter and receiver at both ends are connected to the communication line through the transceiver switch, and the direction is switched. Full duplex is when two wires can transmit different data simultaneously. This mode is full-duplex and can be transmitted in both directions at the same time without switching directions. The serial communication of DC regulated power supply can also be divided into two kinds, one is synchronous communication and the other is asynchronous communication.
