What is RS-485?
RS-485 is a standard defining the electrical characteristics of drivers and receivers for use in serial communications systems. It is commonly used in industrial automation, building automation, and other applications requiring reliable, long-distance communication between multiple devices. It supports data rates up to 10 Mbps and distances up to 1200 meters.
What other technologies are related to RS-485?
RS-485 Competitor Technologies
RS-232
A serial communication standard that, like RS-485, is used for data transmission, but with shorter distances and different electrical characteristics.
RS-422
Another serial communication standard similar to RS-485, offering better noise immunity and longer distances than RS-232, but with different multi-drop capabilities.
I2C
A serial communication protocol often used for short-distance, on-board communication between integrated circuits. It can be a competitor in some embedded applications but typically slower and shorter range.
SPI
A synchronous serial communication interface used for short-distance communication, typically on a PCB. It can compete with RS-485 in certain applications where speed is prioritized over distance and noise immunity.
ARINC 429
A data bus standard used in avionics. It's a competitor in specific application domains where its architecture and features are preferred.
Ethernet
A network protocol for local area networks (LANs), offering high bandwidth and long-distance communication. It competes with RS-485 in applications requiring network connectivity.
CAN
A robust serial communication protocol commonly used in automotive and industrial applications. It can be a competitor where noise immunity and multi-drop capability are important.
MIL-STD-1553
A military standard for data communication, primarily used in aerospace applications. It can be a competitor in specialized domains.
