The goal of the Program is to take a leading role regarding technology within the entertainment industry by creating recommended practices and standards, monitoring standards issues around the
10、world on behalf of our members, and improving communications and safety within the industry. ESTA works closely withthe technical standards efforts of other organizations within our industry, including USITT and VPLT, as well as representing the interests of ESTA members to ANSI, UL, and the NFPA. T
11、he Technical Standards Program is accredited by the American National Standards Institute.The Technical Standards Council (TSC) was established to oversee and coordinate the TechnicalStandards Program. Made up of individuals experienced in standards-making work from throughout our industry, the Coun

The Technical Standards Council employs a Technical Standards Manager to coordinate the work of the Council and its working groups as well as maintain a “Standards Watch” on behalf of members. Working groups incl
13、ude: Control Protocols, Electrical Power, Event Safety, Floors, Fog and Smoke, Followspot Position, Photometrics, Rigging, and Stage Lifts.ESTA encourages active participation in the Technical Standards Program. There are several ways to become involved. If you would like to become a member of an ex
14、isting working group, as have over four hundred people, you must complete an application which is available from the ESTA office. Your application is subject to approval by the working group and you will be requiredto actively participate in the work of the group. This includes responding to letter
15、ballots and attending meetings. Membership in ESTA is not a requirement. You can also become involved byrequesting that the TSC develop a standard or a recommended practice in an area of concern to you.The Control Protocols Working Group, which authored this Standard, consists of a cross section of
16、entertainment industry professionals representing a diversity of interests.

47、etworks” standard ACN. It specifies an architecture including a suite of protocols and languages that may be configured and combined with other standard protocols in a number of ways to form flexible networked control systems.E1.17 Profiles for Interoperability (EPIs) are standards documents that sp
48、ecify how conforming implementations are to operate in a particular environment or situation in order to guarantee interoperability. They may specify a single technique, set of parameters or requirement for the various ACN components. They may also specify how other standards (including other EPIs)
49、either defined within ACN or externally are to be used to ensure interoperability.1 Introductory Discussion1.1 DMX512In the years since its introduction in 1986, USITT DMX512 (often referred to as DMX512 or just DMX) has spread from its initial remit of providing simple level control to dimmers, to control of a huge range of devices. The most recent standard specification is DMX512-A DMX512. Because the semantics of controlling anything except dimmers are outside the scope of any of the DMX512 specifications, there is n
