Standard for Gobo Projection in Public Review

Posted on Monday, December 3rd, 2012

ANSI E1.35 – 2007, Standard for Lens Quality Measurements for Pattern Projecting Luminaires Intended for Entertainment Use, is being revised to increase the accuracy of the measurement procedure, while keeping it simple. The draft of the revised standard is available for free download and comment through 21 January 2013 at the URL below.

E1.35 describes a method for measuring and stating the sharpness of the image projected by a stage and studio luminaire. It’s meant to be a simple way to distinguish quantitatively between luminaires as to the crispness of their projected images.

Two Chain Hoist Rigging Standards in Public Review

Posted on Monday, December 3rd, 2012

Two draft Rigging Working Group standards related to the use of chain hoists in the entertainment industry are available for free download and comment at the URL below through January 28, 2013. Materially affected members of the public are invited to review them.

BSR E1.6-2 – 201x, Entertainment Technology — Design, Inspection, and Maintenance of Electric Chain Hoists for the Entertainment Industry, is part of the E1.6 powered entertainment rigging project. This draft standard covers the design, inspection, and maintenance of serially manufactured electric link chain hoists having capacity of two tons or less and used in the entertainment industry. This standard does not cover attachment to the load or to the overhead structure.

BSR E1.6-4 – 201x, Portable Control of Fixed-Speed Electric Chain Hoists in the Entertainment Industry, is a standard for the controls often used to operate the chain hoists that are the subject of E1.6-2.

Four PLASA Standards in Public Review

Posted on Tuesday, November 20th, 2012

Four PLASA standards are now in public review through the end of this year. Two are proposed reaffirmations of existing standards (no changes), one is a revision of a standard, and one is a new standard. The public review materials for the four standards are available at the URL below.

The two reaffirmations are for ANSI E1.11-2008, Entertainment Technology — USITT DMX512-A — Asynchronous Serial Digital Data Transmission Standard for Controlling Lighting Equipment and Accessories, and ANSI E1.14 – 2001 (R201x), Entertainment Technology — Recommendations for Inclusions in Fog Equipment Manuals. E1.11 is the well-know DMX512-A, a lighting control protocol that is now well over twenty years old, counting back to the original USITT version. E1.14 offers advice for what should be in user manuals for fog machines. It’s a short standard, and it’s free at http://plasa.me/67xd0. The reviews for these two standards run through January 7, 2013.

ANSI E1.19 – 2009, Recommended Practice for the Use of Class A Ground-Fault Circuit Interrupters (GFCIs) Intended for Personnel Protection in the Entertainment Industry, is a standard that offers guidance on using GFCIs to protect personnel. However, one of the problems with GFCIs in electrically noisy environments is that they are prone to tripping even when there is no electrical fault from which people need to be protected. PLASA’s Electrical Power Working Group is proposing to change section four in the existing standard so that it offers recommendations on how to reduce this nuisance tripping. The public review for the revision runs through January 14, 2013.

BSR E1.45 – 201x, Unidirectional Transport of IEEE 802 data frames over ANSI E1.11 (DMX512-A), is draft of a new standard that defines a minimal method to transport IEEE 802 data frames unidirectionally over ANSI E1.11 physical links using an Alternate START Code. The primary motivation is to allow communication of 802 data to luminaires over an ANSI E1.11 DMX512-A datalink for data transmission from those luminaires using Visible Light Communication, IEEE 802.15.7. However, this standard may be used to transport any 802 data for any purpose. Its review runs through January 14, 2013.

BSR E1.45 – 201x, Transport of IEEE 802 data frames over ANSI E1.11 (DMX512-A)

This Standard defines a minimal method to transport IEEE 802 data frames over ANSI E1.11 physical links using an Alternate START Code. The primary motivation is to allow communication of 802 data to luminaires over a ANSI E1.11 DMX512-A datalink for data transmission from those luminaires using Visible Light Communication, IEEE 802.15.7. However, this Standard may be used to transport any 802 data for any purpose.

Review period ends – October 2, 2012

BSR E1.37-2 – 201x, Additional Message Sets for ANSI E1.20 (RDM) – Part 2, IPv4 & DNS Configuration Messages

This draft standard is part 2 of the E1.37 project. It provides additional get/set parameter messages (PIDs) for use with the ANSI E1.20 Remote Device Management protocol. Messages in this document are intended for configuring network interfaces and Domain Name System settings on devices with an IPv4 address.

Review period ends – October 2, 2012

BSR E1.33 – 201x, Entertainment Technology — (RDMnet) — Message Transport and Device Management of ANSI E1.20 (RDM) over IP Networks

This draft standard describes a method of implementing ANSI E1.20 Remote Device Management messaging over an IPv4 network. The primary anticipated use of the standard would be to complement ANSI E1.31 on an IPv4 entertainment lighting control network. This project was originally described as offering extensions to E1.31, but its messages work alongside E1.31 in the same network environment.

Review period ends – October 9, 2012

BSR E1.35 – 201x, Standard for Lens Quality Measurements for Pattern Projecting Luminaires Intended for Entertainment Use

E1.35 describes a method for measuring stage and studio luminaire lens quality with particular emphasis on contrast and perceived image quality (sharpness). It also offers a way for presenting these results on a datasheet in a format that is readily understood by a typical end-user. The procedure specified in this draft is slightly different and more accurate than the procedure specified in the published 2007 edition.
