What is RS232 protocol and how it works?

RS232 is one of the standard protocol in telecommunication which is used for serial communication of data. It is basically the process of connecting signals between data terminal equipment (DTE) for example, file server, routers and application servers, such as a modem.

What are the differences between RS232 and USB?

An USB port is much more sophisticated than an RS-232 serial port. Basically, an RS-232 has a TX pin and an RX pin in which a given side transmits and receives data (respectively), and the other side has the same two crossed over, so one TX connects to the other RX and vice-versa (obviously).

Are rs485/rs232 interfaces or protocol?

The most common serial communication protocols are RS232, RS485, RS422, USB, and Ethernet. But because USB and Ethernet require powerful interfaces with complex protocols, many efficient devices utilized RS232, RS485, and RS422 which is what this note is all about.

How does RS232 communication work?

As RS-232 is a point-to-point asynchronous communication protocol, it sends data in a single direction . Here, no clock is required for synchronizing the transmitter and receiver. The data format is initiated with a start bit followed by 7-bit binary data, parity bit and stop bit which are sent one after another.

What is serial communication and how it works?

In telecommunication and data transmission, serial communication is the process of sending data one bit at a time, sequentially, over a communication channel or computer bus. This is in contrast to parallel communication, where several bits are sent as a whole, on a link with several parallel channels.
