Two original, one revision: new American National Standards projects

Three new projects have been filed with ANSI. Two are for new standards, while one is for the revision of an existing standard. The projects are;

BSR E1.37-8, Additional Message Sets for ANSI E1.20 (RDM) – IPv6 & Improved IPv4 Configuration Messages, is a project to do what the title says: define RDM configuration messages for IPv6 and IPv4. This is a Control Protocols Working Group project.

BSR E1.73, Next Generation Entertainment Control Model: Uniform Device Representation (UDR), is a project to provide a framework by which manufacturers of entertainment equipment can describe controllable and visualisable devices in a digital format. A standard method will be provided to map controllable parameters to existing control endpoints, specifically endpoints associated with the control protocols defined in ANSI E1.11 (DMX512), ANSI E1.20 (RDM), and ANSI E1.31 (sACN). Future control protocols may use this format natively for real-time control. This is a Control Protocols Working Group project.

BSR E1.41, Recommendations for Measuring and Reporting Photometric Performance Data for Entertainment Luminaires Utilizing Solid State Light Sources, is a project to revise the existing standard from 2016. That one was written to give people in the entertainment industry detailed information about the lumen and colour output of units using LED sources. Recent lighting regulations have complicated the market by requiring minimum efficacies and color rendering. The revisions would give guidance on how to measure and report this newly required lighting data. This is a Photometrics Working Group Project.

People with a material interest in these projects are invited to become involved, either by commenting on the draft standards in future public reviews or by joining the appropriate working group. Documents in public review will be posted at Information about joining a working group and links to application forms are available at
