Difference between RS232,RS422,RS485-RS232 vs RS422 vs RS485.

Introduction to RS-422: serial data standard. RS232 RS422 RS449 RS485 20 mA current loop RS422 was introduced to enable higher data rates to be transferred over serial data lines than was possible with RS232. RS422 is able to provide data rates of up to 10 Mbps at distances up to 50 feet (15.24 metres). However using reduced data rates, RS422 is able to transmit data over distances of 4000.

I found just one significant advantage of CAN over RS485 (regarding the physical layer) in which CAN has a fault tolerant mode which enables it to maintain the connection between CANbus nodes through just 1 data wire even though there is one data wire shorted or opened or both data wires are shorted together.

RS232 vs RS485 RS232 and RS485 are standards for data cables. To exchange data between nodes on a network, the most commonly used tools are line drivers and receivers.

When installing an RS422 device in a RS485 bus network should also be noted that a RS422 device RS485 bus network so heavily loaded as 3 RS485 devices, ie the maximum number of devices per station decreases. The following table shows again the main differences between RS422 and RS485 is.

The maximum allowed cable length with RS423 is 1200 meter, just as with RS422 and RS485. The maximum data rate is 100 kbps which is only five times faster than default RS232 and much slower than possible with RS422 and RS485. Detailed information of the interface characteristics of RS423 can be found in the serial interface comparison table.

The RS232 and RS485 1 data transmission interface standards are in widespread use today despite their relatively advanced age—RS232 was introduced almost 50 years ago; RS485, 30 years ago.

The RS-485 Design Guide Figure 4. Example of RS-485 Communication Cable Beyond the network cabling, it is mandatory that the layout of printed-circuit boards and the connector pin assignments of RS-485 equipment maintain the electrical characteristics of the network by keeping both signal lines close and equidistant to another.

RS232 is a standard protocol used for serial communication, it is used for connecting computer and its peripheral devices to allow serial data exchange between them. As it obtains the voltage for the path used for the data exchange between the devices. It is used in serial communication up to 50 feet with the rate of 1.492kbps. As EIA defines.

It is the reason here I am writing an article UART vs USART. But before examining the major differences between UART and USART (UART vs USART), I want to explain what is the asynchronous and synchronous communication. Asynchronous Serial Transmission: In asynchronous communication, there is no common clock between the sender and receiver. It is.
