Two draft standards have been posted for public review on the ESTA website through 7 February 2011 here
- BSR E1.6-2–201x, Entertainment Technology -- Design, Inspection, and Maintenance of Electric Chain Hoists for the Entertainment Industry; and
- BSR E1.37-1–201x, Additional Message Sets for ANSI E1.20 (RDM) - Part 1, Dimmer Message Sets
BSR E1.6-2–201x deals with chain hoists as used in the entertainment industry as part of a performance or in preparation for a performance—not as the warehouse or factory material handling devices.
BSR E1.37-1–201x is part of the BSR E1.37 project to add additional features to RDM. This part is a first installment that provides additional get/set parameter messages (PIDs) that are intended for, but are not limited to, use with entertainment lighting dimming systems. These additional messages allow access to configuration parameters commonly found in many theatrical dimming systems.
