What is RS232?
RS-232 is a standard for serial communication transmission of data. It is commonly used for connecting computer serial ports to peripherals such as printers, mice, and networking devices. It defines the electrical, mechanical, and functional characteristics of the interface between data terminal equipment (DTE) and data circuit-terminating equipment (DCE).
What other technologies are related to RS232?
RS232 Competitor Technologies
RS485
RS485 is a serial communication standard that is often used as a higher-performance alternative to RS232, particularly for longer distances and multi-drop networks.
RS422
RS422 is another serial communication standard similar to RS485, offering improved performance over RS232 in terms of distance and noise immunity.
I2C
I2C is a short-distance serial communication protocol often used for communication between integrated circuits. It serves a different purpose than RS232 but can be used in systems where RS232 might otherwise be considered.
SPI
SPI is another short-distance serial communication protocol. Like I2C, it can be used as an alternative to RS232 in some embedded systems applications.
USB
USB is a much faster and more versatile serial communication standard that has largely replaced RS232 in many applications, particularly in connecting peripherals to computers.
CAN
CAN bus is a robust serial communication protocol primarily used in automotive and industrial applications. While not directly competing in the same space, it fulfills similar data transfer needs in specific domains.
Ethernet
Ethernet is a network protocol that can transmit data serially, but with much higher bandwidth and over much longer distances than RS232. Ethernet is a competitor in applications requiring networking capability.
GPIB
GPIB (IEEE-488) is a parallel communication interface used primarily for connecting test and measurement equipment. While different, it serves a similar function of data transfer in specific applications where RS232 might be used.
