timesRS-422 and RS-485 Standards Overview and System Configurations
The RS-422 and RS-485 standards, as they are known today, are balanced data-transmission schemes that offer robust solutions for transmitting data over long distances and noisy environments. The official titles for these two standards are ANSI TIA/EIA-422 and TIA/EIA-485, respectively, and are revised periodically by the TR-30.2 DTE-DCE Interfaces and Protocols Subcommittee to the Telecommunications Industry Association (TIA) TR-30 Data Transmission Systems and Equipment Committee. For identification, RS-422 and RS-485 suffice.
