ACN Interoperability profiles now in public review

Posted on Monday, July 14th, 2008

This document is part of BSR E1.30-200x, Application level equipment interoperability for control of commonly encountered entertainment technology devices using ANSI E1.17. It specifies how draft DDL modules that may be changed frequently during development shall be marked as experimental.

Review Begins: June 27, 2008, Review Ends: August 26, 2008

All documents, instructions and comments forms are available from the Public Review Documents page:


Draft revision to DMX512-A standard available for comment

Posted on Monday, June 2nd, 2008

BSR E1.11 – 200x, Entertainment Technology–USITT DMX512-A, Asynchronous Serial Digital Data Transmission Standard for Controlling Lighting Equipment and Accessories.

This revision of ANSI E1.11 – 2004, describes a protocol for transmitting digital data used to control entertainment lighting equipment and accessories. Entertainment lighting equipment and accessories includes, but is not limited to, dimmers, robotic luminaires, colour changers, robotic mirrors, dousers, colour wheels, motion effects wheels, and pattern rotators. The revision is being done to correct errors and to clarify text, and to add an Alternate START Code for UTF-8 transmission so that languages other English can be used for sending diagnostic text messages.

Comments close on 8 July, 2008.

(Unofficial note for anyone who wants to read a copy of the DMX512-A standard. The ongoing drafts of this standard, freely available for download and comment, will be almost identical to the one that you will later be able to buy from ESTA or USITT.)


ESTA draft standards available for Rigging, Floors & Power

Posted on Wednesday, April 2nd, 2008

The draft standard describes a means of measuring and specifying the slipperiness of floor surfaces used by performers in live entertainment venues. The standard is not intended to be applied to normal walking and working surfaces, but only to those floor surfaces used by actors, dancers, and other similar artists, when performing before an audience. (How to measure if it’s slippery enough to mop the Tarkett with coke).


Two Fog and Smoke Documents Available From ESTA

Posted on Monday, January 21st, 2008

Two Fog and Smoke documents are available for public review for free on the ESTA website. The public reviews run through March 17.

The first is a reaffirmation of the existing ANSI E1.5 – 2003, Entertainment Technology – Theatrical Fog Made With Aqueous Solutions Of Di- And Trihydric Alcohols. The standard describes the composition of theatrical fogs or artificial mists that are not likely to be harmful to healthy performers, technicians, or audience members of normal working age, which is 18 to 64 years of age, inclusive. It is limited to those fogs and mists made from a solution of water and one or more dihydric or trihydric alcohols, and is intended to be applicable in theatres, arenas, and other places of entertainment or public assembly.

The second is a new draft standard, BSR E1.29 – 20XX, Product Safety Standard for Theatrical Fog Generators That Create Aerosols of Water, Aqueous Solutions of Glycol or Glycerin, or Highly Refined Alkane Mineral Oil. The draft standard is intended to help guide product safety testing laboratories in evaluating fog-making equipment for design or construction defects that might create unacceptable hazards. It is based on ANSI/UL 998 – 2006, Humidifiers, and offers some additions and modifications to the requirements in that UL standard. Products covered are theatrical fog generators rated 600 V or less, and intended for use in professional theatrical entertainment, film and video production, theme parks, and fire safety training.

In addition to being asked to review the documents to see if they offer adequate advice, reviewers are asked to notify ESTA of any protected intellectual property in the draft standards. ESTA does not warrant that its standards contain no protected intellectual property, but it also does not intend to adopt any standard that requires the use of protected intellectual property, unless that property is necessary for technical reasons and can be licensed and used by anyone without prejudice or preference for a reasonable fee.


Phasing Out of Incandescent Lamps – Technical Report Released for Comment

Posted on Monday, January 7th, 2008

The Depart of Climate Change’s Equipment Energy Efficiency (E3) Committee has released the technical report – “Phase-Out of Inefficient Incandescent Lamps and Standards for Compact Fluorescent Lamps” for comment by 1st February. This is the report on which the forthcoming elimination of General Lighting Service incandescent lamps will be based.

There is a recognition in the report that there are many incandescent lamps that are not GLS and that these are not directly targeted for elimination. However we already know from the horrendous problems caused by the implementation of the removal of piggy-back plugs from retail sale, that unintended consequences are no less severe than intended ones.

It would seem that the key number in the report is the minimum required energy efficiency requirement of 20 lumens per Watt. From a greenhouse emissions perspective this number is surprisingly low, but it will mean that many of our current tungsten halogen incandescent lamps will probably make through the process unscathed, even without direct exemptions.

You can download a copy of the report from

and pass your views on to ALIA for inclusion in our submission.
