Overview:
Art-Net is an Ethernet protocol based on the TCP/IP protocol suite. Its purpose is to allow transfer of
large amounts of DMX512 data over a wide area using standard networking technology.
The latest revision of the protocol implements a number of new features and also simplifies the data
transfer mechanism. The changes are all based on feed back from manufacturers who are using the
protocol.
Universe Addressing:
A theoretical limit of 32,768 universes exists in the Art-Net 3 specification. The actual number of
universes that can be transmitted is dependent upon both the network physical layer and whether
unicast or broadcast is used. The following table provides a rule of thumb.

The Port-Address of each DMX512 Universe is encoded as an 15-bit number as shown in the following
table.

The high byte is called the 'Net'. This was introduced at Art-Net 3 and was previously zero. The Net
has a single value for each node. The high nibble of the low byte is referred to as the Sub-Net address
and is set to a single value for each Node.The low nibble of the low byte is used to define the
individual DMX512 Universe within the Node.
This means that any Node will have:
1.One “Net” switch.
2.One “Sub-Net” switch.
3.One “Universe” switch for each implemented DMX512 input or output.
A product designer may opt to implement these as hard or soft switches.

Terminology:
 Node: A device that translates DMX512 to or from Art-Net is referred to as a Node.
 Port-Address: one of the 32,768 possible addresses to which a DMX frame can be directed.
The Port-Address is a 15 bit number composed of Net+Sub-Net+Universe.
 Net: A group of 16 consecutive Sub-Nets or 256 consecutive Universes is referred to as a
net. There are 128 Nets in total.
 Sub-Net: A group of 16 consecutive universes is referred to as a sub-net. (Not to be
confused with the subnet mask).
 Universe: A single DMX512 frame of 512 channels is referred to as a Universe.
 Kiloverse: A group of 1024 Universes.

 A central controller or monitoring device (lighting console) is referred to as a Controller.
 IP: The IP is the Internet protocol address. It is expressed in either a long word format
(0x12345678) or dot format (2.255.255.255). Convention is that the former is hexadecimal
and the latter is decimal. The IP uniquely identifies any Nodes or Controllers on a network.
 Subnet Mask: Defines which part of the IP represents the Network address and which part
represents the Node address. All Art-Net implementations require a Sub-Net mask of
255.0.0.0. This means that the first byte of the IP is the network address and the remaining
three bytes are the Node address.
 Port: Actual data transmission on Art-Net uses the UDP protocol that operates ‘on top of’
the TCP/IP protocol. UDP data transfer operates by transferring data from a specific IP:Port
address on a Node or Controller to a second specific IP:Port address on a second Node or
Controller. Art-Net uses only one port address of 0x1936.
 Directed Broadcast: When a network first connects, the Controller does not know the
number of Nodes on the network, nor does it know their IP addresses. The Directed
broadcast address allows the Controller to send an ArtPoll to all Nodes on the network.
 Limited Broadcast: Art-Net packets should not be broadcast to the Limited Broadcast
address off 255.255.255.255.
 Controller: A generic term describing an Art-Net device with the primary task of generating
control data. For example, a lighting console.
 Node: A generic term describing an Art-Net device with the primary task of receiving
control data. For example, a dimmer or an Ethernet to DMX gateway.
 Media Server: A generic term describing an Art-Net device capable of generating control
data based on the ‘mx’ Media Extensions to Art-Net.

Ethernet Implementation:
General Notes:
 All communication is UDP. Each packet format defined in this document form the Data field
of an enclosing UDP packet.
 Packet formats are specified in a manner similar to C-language structures, in which all data
items are considered to be unsigned integers of type INT8, INT16 or INT32 according to the
number of bits. There are no hidden padding bytes, except at the very end of a packet,
which may be rounded up to a multiple of 2 or 4 bytes. Extra bytes at the end of a valid
received packet are ignored.
 The protocols are generalised for handling future versions with increased numbers of ports.
 Many bit data fields contain unused positions. These may be used in future versions of the
protocol. They should be transmitted as zero and not tested by receivers.
 All packet definitions are designed such that their length can be increased in future
revisions, whilst retaining compatibility. For this reason, only minimum packet length is
checked in this protocol.
Protocol Operation:
A Node operates in one mode, each Node having a unique IP address derived from its Ethernet MAC
address. The UDP port used as sources and destinations is 0x1936.
IP address configuration
The Art-Net protocol can operate on either a DHCP managed address scheme or using static
addresses. By default an Art-Net product will factory start using a Class A IP address scheme. This
allows Art-Net products to communicate directly and without the need for a DHCP server to be
connected to the network.
IP address configuration - DHCP
Nodes report whether they are DHCP capable in the ArtPollReply packet. This document details
packets on the assumption that static addressing is used. When DHCP is used, the addressing and
subnet masks will be modified as dictated by the DHCP server.
IP address configuration – Static Addressing
The use of Class A addressing is allowed within a closed network. It is important to ensure that Art-
Net data is not routed onto the Internet.
Products implementing Art-Net should default to the Primary IP address of 2.?.?.?.
The IP address consists of a 32 bit number designated as A.B.C.D.The lower the bytes B.C.D is
calculated from the MAC address. The high byte ‘A’ is set to one of two values as shown in the
following table.
The MAC address is a 48 bit number designated u:v:w:x:y:z. This is a globally unique number. The
upper three bytes ‘u:v:w’ are registered to a specific organisation. The lower three bytes ‘x:y:z’ are
assigned by that organisation. In order to ensure that there is minimal possibility of IP address
conflicts between different manufacturers supporting Art-Net, the product OEM code is added to the
MAC address.
The ‘B’ field of the IP address is calculated by adding the high byte of the OEM code with the low
byte of the OEM code and the ‘x’ field of the MAC address.
On power up, the Node checks its configuration for IP addressing mode. If it has been programmed to
use a custom IP address, the following procedure is not used.
IP Address A.B.C.D

The sub-net mask is always initialised to 255.0.0.0, unless a custom IP address is in use. This means
that the network address is the most significant 8 bits and the Node address is the least significant 24
bits of the IP address. This is a Class A network address and for this reason care must be exercised
when connecting to other networks. If an installation requires connection of an Art-Net network to
another network that has Internet access, then the connection must be implemented via a router
that filters out the Class A addresses.
IP address Example
Given the following settings, the IP address calculation will be as follows:
Network Switch = Off
MAC address = 12:45:78:98:34:76 (hexadecimal number)
OEM code = 0x0010
Calculation:
IP Address A = 2 (Because Network switch is off).
IP Address B = 114 (98 + 0 + 16).
IP Address C = 34 (from MAC address).
IP Address D = 76 (from MAC address).
IP Address = 2.114.34.76.
Controller Default Poll
By default a Controller should poll both the primary and secondary Art-Net addresses:
 2.255.255.255:0x1936 Primary Art-Net Address
 10.255.255.255:0x1936 Secondary Art-Net Address
Network Topology:
Art-Net allows two network topologies to operate simultaneously:
1.Peer to Peer: This is an unmanaged network where multiple Nodes transfer data without
the intervention of a controller. All data transfer uses ArtDmx packets. All data is Directed
Broadcast. This is the power on mode of operation for all Art-Net compliant nodes designed
to receive DMX512. In Peer to Peer mode, all IP packets are sent to the Directed Broadcast
address 2.255.255.255 (or 10.255.255.255 depending upon the Network Switch setting), and
are therefore received by all Nodes on the same local network.
2.Controller to Peer: This is the most sophisticated implementation whereby one or more
Nodes communicate with one or more central controllers (lighting consoles). This mode of
operation data transfer operates by unicast transmission of ArtDmx packets. This topology
allows greater than 40 universes to be transferred over a single network.
Operation
All UDP packets accepted by the Node conform to the Art-Net protocol specification as defined
below. Any other packets are ignored.

The ArtPoll packet is used to discover the presence of other Controllers, Nodes and Media Servers.
The ArtPoll packet is only sent by a Controller. Both Controllers and Nodes respond to the packet.
A Controller broadcasts an ArtPoll packet to IP address 2.255.255.255 (sub-net mask 255.0.0.0) at UDP
port 0x1936, this is the Directed Broadcast address.
The Controller may assume a maximum timeout of 3 seconds between sending ArtPoll and receiving
all ArtPollReply packets.
The Controller that broadcasts an ArtPoll should also reply to its own message (to Directed Broadcast
address) with an ArtPollReply. This ensures that any other Controllers listening to the network will
detect all devices without the need for all Controllers connected to the network to send ArtPoll
packets.

IP Address Override:
All Art-Net compatible devices provide a temporary override facility that defeats any non-standard IP
address programming.
Setting the Sub-Net switch and all available Universe switches to ‘F’ enables IP override. In IP
override mode, the Node ignores all parameters programmed by ArtIpProg commands.

A Controller or monitoring device on the network can reprogram numerous controls of a node
remotely. This, for example, would allow the lighting console to re-route DMX512 data at remote
locations. This is achieved by sending an ArtAddress packet to the Node’s IP address. (The IP address
is returned in the ArtPoll packet). The node replies with an ArtPollReply packet.
Fields 5 to 13 contain the data that will be programmed into the node.

ArtDmx is the data packet used to transfer DMX512 data. The format is identical for Node to
Controller, Node to Node and Controller to Node.
The Node initially transmits ArtDmx on the Directed Broadcast address.
The Data is output through the DMX O/P port corresponding to the Universe setting. In the absence of
received ArtDmx packets, each DMX O/P port re-transmits the same frame continuously.
The first complete DMX frame received at each input port is placed in an ArtDmx packet as above and
transmitted as an ArtDmx packet containing the relevant Universe parameter. Each subsequent DMX
frame containing new data (different length or different contents) is also transmitted as an ArtDmx
packet.
Nodes do not transmit ArtDmx for DMX512 inputs that have not received data since power on.
However, an input that is active but not changing, will re-transmit the last valid ArtDmx packet at
approximately 4-second intervals.
A DMX input that fails, will not continue to transmit ArtDmx data.
Note 1 Broadcast vs Unicast:
ArtDmx packets can be broadcast, but it is not recommended. Significant network efficiency gains can
be achieved by unicasting ArtDmx. When ArtDmx is Unicast, the following rules must be used:
The transmitting device must regularly ArtPoll the network to detect any change in universe switch
settings.If the transmitting device opts to Unicast, then it must Unicast ArtDmx to all nodes that are
subscribed (In the ArtPollReply) to that universe.Subscribed means any universes listed in both
the Swin and Swout array.
If there are no subscribers to a universe that the transmitter wishes to send, then the ArtDmx may be
broadcast.Implementers should provide for dynamic change between Unicast and broadcast. If the
number of universe subscribers exceeds a given number, it may become more efficient to broadcast.
Use of unicast only is mandatory for systems using greater that 30 universes.

Data [Length]

-
An array of DMX512 lighting data.
Refresh Rate:
The ArtDmx packet is intended to transfer DMX512 data. For this reason, the ArtDmx packet for a
specific IP Address should not be transmitted at a repeat rate faster than the maximum repeat rate of
a DMX packet containing 512 data slots.
Data Merging:
The Art-Net protocol allows multiple nodes or controllers to transmit ArtDmx data to the same
universe.
A node can detect this situation by comparing the IP addresses of received ArtDmx packets. If ArtDmx
packets addressed to the same Universe are received from different IP addresses, a potential conflict
exists.
The Node can legitimately handle this situation using one of two methods:
 Consider this to be an error condition and await user intervention.
 Automatically merge the data.
Nodes should document the approach that is implemented in the product user guide. The Merge
option is preferred as it provides a higher level of functionality.
Merge is implemented in either LTP or HTP mode as specified by the ArtAddress packet.
Merge mode is implemented as follows:
1.If ArtDmx is received from differing IP addresses, the data is HTP merged to the DMX
output. In this situation, ArtPollReply-GoodOutput-Bit3 is set. If Art-Poll-TalkToMe Bit 1 is
set, an ArtPollReply should be transmitted when merging commences.
2.Exit from Merge mode is handled as follows:
 If ArtAddress AcCancelMerge is received, the Next ArtDmx message received ends
Merge mode. The Node then discards any ArtDmx packets received from an IP
address that does not match the IP address of the ArtDmx packet that terminated
Merge mode.
 If either (but not both) sources of ArtDmx stop, the failed source is held in the
merge buffer for 10 seconds. If, during the 10 second timeout, the failed source
Art-Net 3 Protocol Release V1.4 Document Revision 1.4bd 31/8/2011

- 22 -
returns, Merge mode continues. If the failed source does not recover, at the end
of the timeout period, the Node exits Merge mode.
 If both sources of ArtDmx fail, the output holds the last merge result.
Merging is limited to two sources, any additional sources will be ignored by the Node.
The Merge implementation allows for the following two key modes of operation.
 Combined Control:
Two Controllers (Consoles) can operate on a network and merge data to
multiple Nodes.
 Backup:
One Controller (Console) can monitor the network for a failure of the primary
Controller. If a failure occurs, it can use the ArtAddress AcCancelMerge command to take
instant control of the network.
When a node provides multiple DMX512 inputs, it is the responsibility of the Node to handle merging
of data. This is because the Node will have only one IP address. If this were not handled at the Node,
ArtDmx packets with identical IP addresses and identical universe numbers, but conflicting level data
would be transmitted to the network.

A Controller or monitoring device on the network can enable or disable individual DMX512 inputs on
any of the network nodes. This allows the Controller to directly control network traffic and ensures
that unused inputs are disabled and therefore not wasting bandwidth.
All nodes power on with all inputs enabled.
Caution should be exercised when implementing this function in the controller. Keep in mind that
some network traffic may be operating on a node to node basis.

Firmware and UBEA upgrades:
This section defines the packets used to send firmware revisions to a node. In all instances,
communication is private. Under no circumstances should the broadcast address be used.
The transaction involves the controller sending multiple ArtFirmwareMaster packets to a Node’s IP
address. Each packet is acknowledged by the Node with an ArtFirmwareReply.
The controller allows a 20 second maximum delay for reception of the ArtFirmwareReply.
If the reply is not received in this time, the controller aborts the transaction. The large time period is
to allow for Nodes that are writing directly to slow non-volatile memory.
The Node allows a 20 second delay between sending an ArtFirmwareReply and receipt of the next
consecutive ArtFirmwareMaster. If the next consecutive block is not received within this time, the
Node aborts the transaction. In this instance the Node returns to it’s previous operating system and
sets ArtPollReply->Status and ArtPollReply ->NodeReport accordingly.
The firmware update file contains a header that defines the Node OEM values that are valid for this
update. The Controller must check this value before sending to a Node. The Node also checks this
data on receipt of the first packet. If the Node receives a packet with an invalid code, it sends an
error response.
The UBEA is the User Bios Expansion Area. This is a limited firmware upload mechanism that allows
third party firmware extensions to be added to a Node.
Manufacturers who implement this feature must document the software interface requirements.

RDM Support:
This section defines the packet structure used to gate the Remote Device Management (RDM) protocol
across Art-Net. It is assumed that the reader is familiar with the RDM document.
Art-Net devices support RDM as follows:
 All RDM discovery commands are proxied; Art-Net devices hold local RDM device lists and
conduct their own discovery.
 All RDM Get / Set commands are non-proxied; they are passed to end devices for response.
This document defines the following terms:
 Input Gateway: A device that inputs DMX512 onto the Art-Net network (e.g. Up-Lynx).
 Output Gateway: A device that outputs DMX512 from the Art-Net network (e.g. Down-
Lynx)
 Table of Devices (TOD): The list of RDM devices maintained by both Input and Output
Gateways.
RDM Discovery
Output Gateway Operation
Output Gateways perform RDM discovery independent of network operation. This includes full
discovery upon power-on and incremental discovery as a background task. The Output Gateway
informs the network about its TOD as follows:
 Upon receipt of an ArtTodRequest packet, the Output Gateway Directed Broadcasts an
ArtTodData packet containing the entire TOD. All Input Gateways parse the ArtTodData
packets. If the Sub-Net and Universe fields match, the Input Gateway adds the TOD
contents to their own internal TOD. This allows Input Gateways to respond to any RDM
discovery commands they receive.
 Upon completion of initial RDM discovery, Output Gateways Directed Broadcast their TOD in
an ArtTodData packet.
 When an RDM device is added to or removed from the Output Gateway’s TOD (during
incremental discovery), an ArtTodData packet is broadcast automatically.
Art-Net 3 Protocol Release V1.4 Document Revision 1.4bd 31/8/2011

- 27 -
Input Gateway Operation
Input Gateways generate a TOD by monitoring Art-Net traffic. The TOD is then used to reply to RDM
discovery commands by proxy. Operation is as follows:
 Upon power-on, Input Gateways Directed Broadcast an ArtTodRequest packet.
 The network is monitored for ArtTodData packets. If the Sub-Net and Universe fields
match, the Input Gateway adds the TOD contents to its own internal TOD. This allows Input
Gateways to respond to any RDM discovery commands they receive.
 Input Gateways do not transmit any RDM discovery messages to the network.
Controller Operation:
Controllers emulate the operation of Input Gateways.
ArtTodRequest
:
This packet is used to request the Table of RDM Devices (TOD). A Node receiving this packet must not
interpret it as forcing full discovery. Full discovery is only initiated at power on or when an
ArtTodControl.AtcFlush is received.
