Definition

A standard defining serial communication between computers and modems e. g. was originally drafted by the radio sector as RS-232. Later it was taken over by the EIA as EIA-232. Later this standard was managed by the TIA and the name was changed to the current TIA-232. Because the EIA was accredited by ANSI to help develop standards in its areas, the standards are often described as e. g. ANSI TIA-232 (or formerly as ANSI EIA/TIA-232')

Electronic Industries Alliance

The Electronic Industries Alliance (EIA, until 1997 Electronic Industries Association) was a standards and trade organization composed as an alliance of trade associations for electronics manufacturers in the United States. They developed standards to ensure the equipment of different manufacturers was compatible and interchangeable. The EIA ceased operations at the end of 2010, but the former sectors continue to serve the constituencies of EIA.[1]

Well known EIA standards include:

  • RS-170 (the black & white video signal standard before NTSC)
  • RS-232, EIA-422, RS-449, EIA-485 for serial data communications
  • EIA-274, also known as G-code in the machine tool industry and Gerber File in the PCB manufacturing industry, is the most common NC code format
  • RS-279 electronic color code originally known as the RETMA color code
  • EIA-708 (a closed captioning standard for ATSC)
  • EIA-568/TIA-568 Commercial Building Telecommunications Cabling Standard
