Three PLASA standards are now in public review. The public review materials for the standards are available at the URL below. The last day to comment for each of them is April 1. The reviews have ended when April 2 starts.
BSR E1.44 – 201x, Common Show File Exchange Format for Entertainment Industry Automation Control Systems – Stage Machinery, defines a common show file format for the exchange of automation control data between control systems by different manufacturers of stage machinery.
BSR E1.45 – 201x, Unidirectional Transport of IEEE 802 Data Frames Over ANSI E1.11 (DMX512-A), 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.
BSR E1.48 – 201x, A Recommended Luminous Efficiency Function for Stage and Studio Luminaire Photometry, specifies an energy-based luminous efficiency function V(lambda) based on recent research for use when measuring the lumen output for any stage or studio luminaire in which it is known or believed that 20% or more of the output power is at wavelengths shorter than 500nm. Most light meters in use today use the 89-year-old CIE 1924 V(lambda) function. It’s wrong, so the meters are wrong. This standard is intended to encourage the use of a far more accurate V(lambda) function in the entertainment industry.
