Product Introduction: RS232 is a commonly used serial device, which is generally used for data transmission in the field of communication and human-computer interaction. Although the serial port system is more complex than the parallel port system, it requires less data line than the parallel port system in data transmission, so it is more efficient.RS232 only needs 3 data transmission lines to complete the data transmission.These three wires are used for “sending data”, “receiving data” and signal grounding wire respectively. In this connection, the send and receive lines are used to send and receive data between computers.As its name suggests, […]
