  1. Networks & Protocols

  2. Conventional DMX Networks More Complex Moving lights Large shows Inefficient Cost Requirements of today

  3. Ethernet DMX Networks Ethernet distributing DMX Flexible Cost efficient

  4. Modern DMX Requirements Large amount of universes Console merging Cost and time for cabling

  5. Protocols ACN ARTNET DMX 512-A RDM ADN (ADB protocol)

  6. ACN ESTA Still under development started 1997 published Dec 2006: architecture work in progress in ESTA Protocols Working Group: DMX-in-ACN, RDM-in-ACN first free software code being circulated March 2007

  7. ACN standard of controlling light, sound, AV, mechanics future standard to send DMX protocol on top of Ethernet

  8. ARTNET Artistic License (Not ESTA) Version 1 in close cooperation with ADB R&D DMX 512 (and RDM) over Ethernet And macros, remote monitors, remote keys Several manufacturers ACN vs ARTNET Protocol on top of Ethernet

  9. DMX512-A fully backwards compatible higher levels of electrical protection pins 4 & 5 are defined galvanic isolation Text & Test packet RDM

  10. RDM bi-directional communication messages are inserted between DMX packets pins 2 and 3 address firmware upgraded status and fault information

  11. RDM in practice Plugfest PLASA March 2007: only works well when no DMX is transmitted tests say: max. 2 splitters / boosters in cascade

  12. ADN ADN Advanced Dimmer Network bi-directional communication on the second data pair in the DMX cable independent of the DMX signal it exists and it works... TOC

  13. Ethernet / DMX 512 Will Ethernet replace DMX512? NO: Small installations NO: Ethernet is the carrier to send DMX 512 by standard Ethernet protocol. NO: Daisy-chained such as DMX, ADN, RDM

  14. ADB / RDM RDM RDM over Ethernet RDM in ArtNet RDM pin 2/3 TOC

  15. ADB / ACN ACN Hardware Software DMX/RDM over ACN TOC

  16. Wireless Networks WLAN => Carrier for Ethernet Don’t use WLAN for DMX =>Use wired ACN or ART-NET Ok for Software upgrade – status – remote programming Some solutions exist => dedicated products

  17. Questions? Thanks for your time!
