RS232 Serial Port: 7 Facts You Need to Know before Using

RS232, or Recommended Standard 232, was first introduced in 1960 by the Electronic Industries Association (EIA) and has since become a widely used protocol in computer communication. In our new blog, we will explore what RS232 is, how it works, what it is used for, its advantages and disadvantages, and the different types of RS232 cables available.

What Is RS232?

RS232 is a standard communication protocol that defines the electrical and physical characteristics of a serial communication system.

It is used for data transfer between two devices and is typically used for short-distance communications. RS232 uses a single-ended signal, which means that it sends data over a single wire.

How Does RS232 Work?

RS232 works by sending a signal over a wire from one device to another. The signal is sent as a series of voltage levels that represent the data being transmitted. These voltage levels can be either positive or negative, with zero volts being used as a reference point. RS232 also includes a clock signal that is used to synchronize the data transmission between the two devices.
