See A list of productions supporting E1.31
From ESTA.org and supported by http://www.esta.org/tsp/working_groups/CP/projs.html and http://www.sandsys.com/acn/sandnet_acn.htm :
BSR E1.31, Lightweight streaming protocol for transport of DMX512 using ACN.
But on http://en.wikipedia.org/wiki/DMX512-A there are an other description under the heading "Development":
ESTA has initiated a project numbered E1.31 to define an interoperable CAT5 transport for DMX512.
This probably should not refer to transferring the data bytes of DMX over IP networks, not EIA485 electrical signals over twisted pair of CAT 5 quality.
ANSI numbers
Many DMX related standards have been numbered/revised by the American National Standards Institute.
Entertainment Technology -- USITT DMX512-A -- Asynchronous Serial Digital Data Transmission Standard for Controlling Lighting Equipment and Accessories . See DMX
ANSI E1.17 2006 - Entertainment Technology - Architecture for Control Networks . DMX over ACN
Entertainment Technology--Remote Device Management over USITT DMX512 . RDM over DMX
The above is found via http://webstore.ansi.org/
Note that DMX512-A was updated in 2004 and again in 2008: http://www.esta.org/tsp/news/newsdetails.php?newsID=291 (regarding text mesasges in UTF-8, update rate almost up to 20*44 Hz, corrections of errors and clarifications)
Current drafts
The drafts for new standards seems to be made by ESTA who has this list currently:
http://www.esta.org/tsp/working_groups/CP/projs.html
E1.31 covers basic DMX through ACN, and E1.33 will extend E1.31 to include RDM data transmissions. Ref: News from USITT http://www.usitt.org/sightlines/v46/n10/stories/EstaNewStandards.html#dmx which is also cited here [1]
The RDM protocol is to be extended with BSR E1.37 e.g. for bulk data transfer.
