Differences Between RS-232, RS-485, and RS-422 Standards

Serial Communication refers to a communication method for data transmission through serial ports. Data is transmitted bit by bit through data signal lines and ground lines. Common serial ports include RS-232, RS-485, and RS-422. It is important to note that serial ports are only interface standards, specifying the electrical standards of the interface, and not … Read more
