Three draft standards are available now for their first public reviews until 17:00 US Eastern Time, on December 9, 2003.

BSR E1.17, Entertainment Technology - Multipurpose Network Control Protocol Suite, is the draft standard that developed out of the Advanced Control Network study project, and is often referred to by the acronym "ACN," although those initials do not appear in the title of the draft standard. The draft standard defines a suite of protocols offering needed services in network management, device management, device description, and device control with reliable multi-cast transport on data networks that use the common Internet Protocols. The protocol suite's purpose is to allow diverse systems of entertainment equipment and network devices from different manufacturers to fully interoperate.

BSR E1.20, Entertainment Technology - Remote Device Management over USITT DMX512, describes a method of bi-directional communications over a USITT DMX512/1990 data link between an entertainment lighting controller and one or more remotely controlled lighting devices. The protocol is also intended to work with the E1.11 control protocol (a revised version of DMX512) being developed concurrently by the Control Protocols Working Groups.

BSR E1.25, Recommended Basic Conditions for Measuring the Photometric Output of Stage and Studio Luminaires by Measuring Illumination Levels Produced on a Planar Surface, describes the basic testing conditions (e.g. the condition of the luminaire, the power supply, et cetera) for any a of a number of methods of measuring a luminaire's output that involve shining the light from the luminaire on a flat wall and then measuring the levels of illumination produced. The draft standard does not describe the equipment or measurement method used to measure the illumination.
