Lighting TechnologiesYOUR PARTNER FOR LIGHT

Networks & Protocols


Conventional DMX Networks

• More Complex– Moving lights– Large shows

• Inefficient– Cost – Requirements of today


Ethernet DMX Networks

• Ethernet distributing DMX– Flexible – Cost efficient


Modern DMX Requirements

• Large amount of universes

• Console merging

• Cost and time for cabling


Protocols

• ACN

• ARTNET

• DMX 512-A

• RDM

• ADN (ADB protocol)


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


ACN

• standard of controlling light, sound, AV, mechanics

• future standard to send DMX

• protocol on top of Ethernet


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


DMX512-A

• fully backwards compatible

• higher levels of electrical protection

• pins 4 & 5 are defined

• galvanic isolation

• Text & Test packet

• RDM


RDM

• bi-directional communication

• messages are inserted between DMX packets

• pins 2 and 3

• address

• firmware upgraded

• status and fault information


RDM in practice

Plugfest PLASA March 2007:

– only works well when no DMX is transmitted– tests say: max. 2 splitters / boosters in

cascade


ADN

TOC

• 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...


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


ADB / RDM

TOC

• RDM

– RDM over Ethernet– RDM in ArtNet– RDM pin 2/3


ADB / ACN

TOC

• ACN

– Hardware – Software – DMX/RDM over ACN


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
