2.3 ANSI
The American National Standards Institute (ANSI) is an organization composed of representatives from industry
and government that collectively determine standards for the electronics industry as well as many other fields,
such as chemical and nuclear engineering, health and safety, and construction. ANSI also represents the United
States in setting international standards. New electronic equipment and methods must undergo extensive testing
to obtain ANSI approval.
In 2004, ANSI approved the DMX 512 standard, and has since approved several other related standards
including Remote Device Management (RDM) and Architecture for Control Networks (ACN). The actual
standards are listed below:
•
ANSI E1.11-2004 - Entertainment Technology USITT DMX512-A - Asynchronous Serial Digital Data
Transmission Standard for Controlling Lighting Equipment and Accessories
•
ANSI E1.20 - Entertainment Technology RDM - Remote Device Management over USITT DMX512
•
ANSI E1.17 - Entertainment Technology ACN – Architecture for Control Networks (Multipurpose
Network Control Protocol Suite)
2.4 EIA/TIA
The Electronics Industry Alliance (EIA) is a trade organization composed of representatives from electronics
manufacturing firms across the United States. EIA began in 1924 as the Radio Manufacturers Association
(RMA), and has grown to include manufacturers of televisions, semiconductors, computers, and networking
devices. The group sets standards for its members, helps write ANSI standards, and lobbies for legislation
favorable to growth of the computer and electronics industry.
The EIA is composed of several subgroups including the Telecommunications Industry Association (TIA). The
EIA/TIA-485 standard is the communication basis for DMX 512.
