... connectors (EIA-574) are sometimes used. The EIA has also defined faster standards for serial communications, including EIA-422 (balanced signals), EIA-423 (unbalanced), EIA-485 (multi- point), and EIA-530 (EIA-422 with 25-pin D con- nector). EIA standards additionally encompass wiring connec- tors and topology, including building wiring and net- work backbones. EIAITIA ... CRC Press LLC Fib...
