![]() The sender device stores data in its buffer and then sends the data through the cable (or PCB trace), and the receiver then stores this data in its buffer. The communication principle of RS-232 communications is simple. ![]() The RS-232 uses a positive voltage for transmission of a low logic level signal (0) and a negative voltage for transmission of a high logic level signal (1).Įxample RS-232 signals RS-232 Voltage Levels This standard is still often used today in various electronic devices, including computers, automation, and medical devices. At one time, RS-232 was the most commonly used data transmission format and was mainly implemented using a standard 9 pin D-sub (DB-9) connection. RS-232, which stands for Recommended Standard 232, is an electronic device protocol standard used for data transmissions between electronic devices created in 1960. In this article, we will be looking at the legacy RS-232 protocol standard. ![]() We hope this information will prove valuable next time you need to implement a serial communication bus in your design, helping you select the most appropriate option for your circuit. ![]() The articles will cover a few of the more popular protocols and standards in use today, and at the end of this series, we will recap and compare the advantages and disadvantages of each. In this series of articles, we’re looking at some of the different types of Serial Communication Protocols available for transferring data between devices. ![]()
