What DMX-Over-Ethernet protocols does CueServer support?

These days you don't have to hang around the lighting world for long to hear terms like sACN, Art-Net, or Ki-Net. These are DMX-Over-Ethernet protocols. These protocols allow the transportation of a DMX lighting signal over a standard Ethernet network. CueServer 2 comes packed with support for the transmission and reception of DMX lighting control data over the three major Ethernet Protocols.

sACN (or Streaming ACN)

sACN is a preferred method of sending and receiving DMX-over-Ethernet to and/or from a CueServer.

The following table lists the general specifications for the CueServer implementation of sACN:
  • Compliant with ANSI Standard E1.31-2009 (sACN)
  • May send and/or receive up to 128 universes of sACN simultaneously
  • May send and/or receive sACN packets with an arbitrary universe number between 1 and 63999
  • sACN is sent at a maximum rate of 40Hz for each universe when channel values are changing
  • sACN is sent at a minimum rate of 1Hz for each universe when channel values are static
  • Supports the sending of user-defined priority levels for each universe
  • Received sACN is merged with hardwired DMX designated for the same universe
  • Ignores incoming data marked as Preview Data
  • Performs immediate stream termination when a Stream Terminated packet is received
  • Maintains proper sequence number transmission separately for each output universe
  • Sends the universe’s name as the sACN source name for each universe
  • Ignores packets with start code 0xDD (used for slot-by-slot priority)
  • Each universe times out after 2.5 seconds when no packets for that universe are not received
CueServer does not receive its own sACN output For more information about sACN, please visit the ESTA Technical Standards Program at tsp.esta.org.

Art-Net

Art-Net is a method of sending and receiving DMX-over-Ethernet to and/or from a CueServer.

Art-Net is owned and copyright by Artistic Licence Holdings Ltd. Artistic Licence has published the specification and made it available for anyone to use on a royalty-free basis.

The following table lists the general specifications for the CueServer implementation of Art-Net:

  • Compliant with the Art-Net 3 Specification by Artistic License
  • May send and/or receive up to 128 universes of Art-Net simultaneously
  • May send and/or receive Art-Net packets with an arbitrary port address (network/sub-net/universe) from 0:0:0 thru 127:F:F
  • Art-Net is sent at a maximum rate of 40Hz for each universe when channel values are changing
  • Art-Net is sent at a minimum rate of 1Hz for each universe when channel values are static
  • Art-Net may be sent to the limited broadcast address, directed broadcast address or unicast to a specific IP address
  • Received Art-Net is merged with hardwired DMX designated for the same universe
  • Maintains proper sequence number transmission separately for each output universe
  • Each universe times out after 6 seconds when no packets for that universe are not received
  • CueServer’s implementation of Art-Net does not yet support “automatic” IP configuration via the ArtPoll method
  • CueServer does not receive its own Art-Net output

Ki-Net (v1 & v2)

KiNET is an alternate method of sending DMX lighting control values to from a CueServer to lighting fixtures and/or power supplies that support the proprietary Philips/Color Kinetics KiNET protocol.

The following table lists the general specifications for the CueServer implementation of KiNET:

  • Compliant with the v1 and v2 versions of the KiNET protocol
  • May send and/or receive up to 128 universes of KiNET simultaneously
  • A universe outputting KiNET v1 may be sent to any arbitrary IP address
  • A universe outputting KiNET v2 may specify a port number and DMX range
  • KiNET is sent at a maximum rate of 40Hz for each universe when channel values are changing
  • KiNET is sent at a minimum rate of 1Hz for each universe when channel values are static
