Its not, it just happens to be convenient. Other standards for UART communication include RS-422, RS-423, RS-481, and various others.
Different data rate speed (for rs232 is lower), usb is more flexible and takes less energy. Different instructions and commands. If you are a programmer then it's easier for to work with usb then with rs232.
A UART is a device used for serial communication. They are commonly used to drive the RS232 ports on computer equipment, and used to be common in computer terminals, modems, etc. A UART includes a shift register which accepts data as bytes and produces a stream of bits, a data buffer which allows multiple bytes to be stored while awaiting their turn to be shifted out and various control and signaling logic components.
RS232 means "Recommended standard no. 232", EIA standard for serial communication Thirumalesha.....
Yes. Actually we can communicate with ZigBee module through UART. So UART itself is a full Duplex communication. So we can use ZigBee for full Duplex communication.
UART stands for Universal Asynchronous Receiver Transmitter.UART (Universal asynchronous receiver / transmitter) is responsible for performing the main task in serial communications with computers. This device changes incoming parallel information to serial data which can be sent to communication line. UART is capable of encapsulating a byte that might be 5, 6, 7 or 8 bits wide in start and stop bits. Moreover it can attach an extra parity bit with the data for error detection. The width of stop bits may also vary. UART performs all the tasks, timing, parity checking, etc. needed for the communication.
Difference between Rs232 and RS485 is Only Distance RS232 is not for long or far distance .. but RS485 can be use for LONGEST distance ..RS232 is single ended communication where as RS485 is Differential communication.Max.no of receivers in RS232 is only ONE, whereas in RS485 is 32.Max.no of transmitters in RS232 is only ONE whereas in RS485 is 32.IN RS232 there is no pin to change from transmitter mode receiver mode. But, In RS485 have DE pin to set transmitter mode and RI to set receiver mode.
RS422 and RS485 and the now popular USB
rs232
rs232 isfaster than rs449
Information and Communication Tecnology. Phones Internet TV RS232 IDE SATA USB Not included, Not excluded. in general any device used/made for communication. Regards.
Yes, you can get a USB to RS232 converter (aka USB to Serial).
I2C (Inter-Integrated Circuit) is a serial communication protocol that uses two wire lines for communication, allowing multiple devices to be connected in a network. RS232 (Recommended Standard 232) is a serial communication standard that uses a single wire for data transfer and is commonly used for connecting devices like modems, printers, and GPS receivers. Additionally, RS232 uses voltage levels for signaling while I2C uses open-drain signals.
