Electronic Industries Alliance

The EIA ( Electronic Industries Alliance) was an American business association that has developed a number of important standards to ensure the cooperation of devices from different manufacturers. The Association as such has dissolved the end of 2010, but the tasks are carried on by the individual organizations.


In 1924 the U.S. radio manufacturers banded together under the name Associated Radio Manufacturers to rename itself in the same year in Radio Manufacturers Association (RMA). The upturn in the electronics brought new tasks, new members and corresponding name change: 1950 in Radio Television Manufacturers Association ( RTMA ), 1953 in Radio Electronics Television Manufacturers ( RETMA ) and 1957 in Electronics Industries Association ( EIA). 1997 was the last place in renaming Electronics Industries Alliance (EIA ); which reflected the development away from the pure resist Manufacturers Association.

The seat of the EIA was in Arlington, Virginia. Last belonged to the Association the following organizations:

At the beginning of 2011, the business association is dissolved. The individual organizations perform the appropriate tasks on. The EIA standards will in future be managed by the ECA, whose name will also disappear because the ECA has united at the same time with the National Electronic Distributors Association ( NEDA) to the new Electronic Components Industry Association ( ECIA ).


The EIA has produced a number of important standards and norms, such as RS- 232 as the standard for modem connections worldwide and EIA -422 (formerly RS -422 ), RS -423 and EIA- 485 (formerly RS -485).

The function and change of name of the association have also been reflected in the names of these standards and provide up today for confusion.

Originally, the standards with the prefix RS and a number have been identified, RS meant Radio Sector. With the expansion to other disciplines (except radio) while the prefix was retained, but was officially no longer abbreviation. Today RS is usually read as a Recommended Standard ( backronym ).

In later years, the EIA has identified new standards and new versions of existing standards with the prefix EIA. With the establishment of the TIA TIA prefix was used by the subordination of the TIA under the EIA finally EIA / TIA for communication standards. The American National Standards Institute (ANSI), the U.S. Office for Standardization, has accredited the EIA and later the TIA and therefore the standards officially received the prefix ANSI EIA or ANSI EIA / TIA.

As a result, a single standard, such as the known standard 232 for the serial port, or optional RS -232, EIA -232, TIA -232, EIA/TIA-232, EIA ANSI -232, ANSI EIA/TIA-232, and be called on. Formally correct of course is what is on the Standard: The standard 232 the current version ANSI EIA/TIA-232-F-1997, that is, from 1969, however, RS- 232 -C. The suffix -F or -C identifies the version of the standard that have to be followed in more recent versions of the year.

The EIA was also the initiator and co-founder of the Internet Security Alliance.
