YOUR PARTNER FOR LIGHT
Conventional DMX Networks
• More Complex
– Moving lights
– Large shows
• Inefficient
– Cost
– Requirements of today
Lighting Technologies
YOUR PARTNER FOR LIGHT
Ethernet DMX Networks
• Ethernet distributing DMX
– Flexible
– Cost efficient
Lighting Technologies
YOUR PARTNER FOR LIGHT
Modern DMX Requirements
• Large amount of universes
• Console merging
• Cost and time for cabling

Protocols
•
•
•
•
•
ACN
ARTNET
DMX 512-A
RDM
ADN (ADB protocol)
Lighting Technologies
YOUR PARTNER FOR LIGHT
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
Lighting Technologies
YOUR PARTNER FOR LIGHT
ACN
• standard of controlling light, sound, AV,
mechanics
• future standard to send DMX
• protocol on top of Ethernet
Lighting Technologies
YOUR PARTNER FOR LIGHT
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
Lighting Technologies

DMX512-A
•
•
•
•
•
•
fully backwards compatible
higher levels of electrical protection
pins 4 & 5 are defined
galvanic isolation
Text & Test packet
RDM
Lighting Technologies
YOUR PARTNER FOR LIGHT
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
Lighting Technologies
YOUR PARTNER FOR LIGHT
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...

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
Lighting Technologies

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

ADB / ACN
•
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
