Recommended Standard

EIA standards

With the changing names of the EIA, the naming convention of the standards was also adapted. For example, a standard defining serial communication between computers and modems e.g. was originally drafted as a Recommended Standard, thus the "RS" 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. Some EIA standards also were branded as ECA standards. Because the EIA is accredited by ANSI as a Standards Developing Organization (SDO) to develop standards in certain areas, these standards are designated as (e.g. ANSI TIA-232, or formerly as ANSI EIA/TIA-232). As currently authorized, any ANSI standard designated at ANSI EIA-xxx is developed or managed by ECA (and, in the future, ECIA).
