Follow our official account to receive timely updates on new articles. Introduction: RS-232, RS-485 and RS-422 are standards defined and published by the Electronic Industries Alliance (EIA). EIA is an American industry association focused on developing and promoting standards in the electronics and electrical industries. Among these, RS-485 is highly praised and widely used in … Read more
1. RS-232 RS-232-C is a serial physical interface standard established by the Electronic Industry Association (EIA) in the United States. RS stands for “Recommended Standard,” 232 is the identification number, and C indicates the revision number. Its full name is “Serial binary data exchange interface technology standard between Data Terminal Equipment (DTE) and Data Communication … Read more
These communication standards play different roles in industrial automation. Let me use a traffic system analogy to help you understand: Basic Positioning of the Four Standards 1. RS-232: A One-to-One Small Road Features: The earliest serial communication standard (1969) Point-to-point full-duplex communication (simultaneous two-way) Single-ended signal transmission (susceptible to interference) Typical transmission distance ≤ 15 … Read more
The RS-485 interface forms a half-duplex network, typically using a two-wire system with shielded twisted pair transmission. This wiring method allows for a bus topology structure, enabling up to 32 nodes to be connected on the same bus. Initially, data was output as analog signals for simple process quantities, and later, the RS-232 interface was … Read more

1. Different Paths, Same Goal RS-232, RS-422, and RS-485 all belong to UART, which stands for Universal Asynchronous Receiver/Transmitter. They can complete communication using just two signal lines (Rx and Tx); However, due to the different voltage levels used by each, converting from UART to RS-232, RS-422, or RS-485 requires a conversion chip like the … Read more
