BSR E1.27-2, Entertainment Technology - Standard for Permanently Installed Control Cables for Use with ANSI E1.11 (DMX512-A) and USITT DMX512/1990 Products, is available for public review through November 19, 2007. The draft standard describes the types of cable to be used in permanent installations to interconnect lighting equipment that comply with ANSI E1.11-2004 (DMX512-A) or with USITT DMX512/1990. The description includes definitions of acceptable cable and connector types and the ways in which they may be used.

August 16, 2007 - New Powered Rigging Standard Project: Electric Chain Hoist Control
The BSR E1.6 project to develop an American National Standard for powered theatrical rigging systems has a new project and part to the standard: E1.6-4, Control of Serially Manufactured Electric Chain Hoists Used in the Entertainment Industry. The E1.6 document has been broken into parts to facilitate its development and to better match the expertise of the people writing it. This newest part is an offshoot of the BSR E1.6-3 project, Selection and Use of Serially Manufactured Electric Chain Hoists in the Entertainment Industry. That project is to specify how chain hoists can be used safely in entertainment applications, which are very different from the applications for chain hoists in factories and materials handling situations. It has became clear that chain hoist control system safety is a complex topic, so the Rigging Working Group, at its meeting on 13 July 2007, voted to give control systems their own E1.6 part and development project.

August 16, 2007 - ANSI E1.11-2004 Revision Project Started
The Controls Protocols Working Group has started work to revise ANSI E1.11-2004, Entertainment Technology--USITT DMX512-A, Asynchronous Serial Digital Data Transmission Standard for Controlling Lighting Equipment and Accessories. The work at this time is focused on correcting errors in the published standard and rewriting difficult sections of text that have been shown to be confusing to readers who do not have American English as their native language. Most of the errors are clearly typographical or cut and paste errors, but correcting them may be considered making substantive changes to the document.
