BSR E1.4-2, Entertainment Technology – Statically Suspended Rigging Systems, is a new draft standard for statically suspended rigging systems (dead-hung battens and grids) permanently installed in performances spaces, places of assembly, and other areas used for entertainment purposes. It establishes minimum performance criteria, recommendations and guidelines that can be used for installation, use, maintenance and inspection purposes. Comments are due before the end of the day 17 June 2019.

ANSI E1.27-2 — 2009 (R2014), Entertainment Technology — Recommended Practice for Permanently Installed Control Cables for Use with DMX512-A Products, is an existing standard being considered for reaffirmation. It’s the second part of a two-part standard for DMX512 cabling, and is for permanently installed cables. The first part, ANSI E1.27-1, is for portable control cables. Comments are due no later than 1 July 2019. 

ANSI E1.30-3 — 2009 (R2014), EPI 25 Time Reference in ACN Systems Using SNTP and NTP, is another existing standard being considered for reaffirmation. It’s another recipe in the E1.30 cookbook for ACN. It offers ways of providing a time reference so that events can be synchronized. Comments are due no later than 1 July 2019.

ANSI E1.30-10 — 2009 (R2014), EPI 32, Identification of Draft Device Description Language Modules, is another existing standard being considered for reaffirmation. It recommends way of identifying a Device Description Language Module for ACN as a trial version, one under development, not for release yet. ANSI E1.30-10 is part of an open series of E1.30 documents that suggests ways of doing common tasks with ANSI E1.17, Architecture for Control Networks. Comments are due no later than 1 July 2019.

BSR E1.59, Entertainment Technology–Object Transform Protocol (OTP), is a new draft standard describing a mechanism to transfer object transform information such as position, orientation and velocity over an IP network using a subset of the [ACN] protocol suite. It covers data format, data protocol, data addressing, and network management. Data transmitted is intended to coordinate visual and audio elements of a production and should not be used for safety critical applications. The document’s authors are anxious to get some public review response on the document. Please respond with “Yes” if the draft is acceptable; responses need not be limited to objections. Comments are due no later than 1 July 2019.
