The DMX In CHOP receives channels from DMX, Art-Net or sACN devices. Channel values for DMX are 0-255.

A Filter Table can be provided in a DAT where addresses can be specified by adding rows for each channel and specifying net, subnet and universe.

ENTTEC NOTE: - Use ENTTEC's NMU (Node Management Utility) to configure and inspect the ENTTEC devices found on your network.

Parameters - Port Page

Active active - Connects to the device while On.

Interface interface - - Select the type of interface to connect to the device with.

  • Enttec Generic Serial serial - Uses the operating system's serial calls to read data.
  • Enttec USB Pro enttecusbpro -
  • Enttec USB Pro Mk2 enttecusbpromk2 -
  • Art-Net artnet - Sets the interface to Art-Net protocol.
  • sACN sacn - Sets the interface to sACN protocol.

Device device - Select a DMX device from the menu.

Serial Port serialport - When the Interface parameter is set Generic Serial this parameter lets you select which Serial (COM) port to use.

Format format - - Select between receiving Packet Per Sample (Timesliced), Packet Per Channel (Latest) or Packet Per Channel (All). When selecting Packet Per Channel (Latest), any messages outside the last cook are being discarded while the option Packet Per Channel (All) will append channels that would get otherwise skipped by dropped frames.

  • Packet Per Sample (Timesliced) packetpersample -
  • Packet Per Channel (Latest) packetperchan -
  • Packet Per Channel (All) packetperchanall -

Art-Net Net (0-127) net - When the Interface parameter is set to Art-Net, this sets the net address. A net is a groups of 16 consecutive subnets or 256 consecutive universes. The range for this parameter is 0-127. This is not a network IP address.

Art-Net Subnet (0-15) subnet - When the Interface parameter is set to Art-Net, this sets the subnet address. A subnet is a group of 16 consecutive universes. The range for this parameter is 0-15. This is not a network subnet mask.

Art-Net Universe (0-15) universe - When the Interface parameter is set to Art-Net, this sets the universe address. A single DMX512 frame of 512 channels is referred to as a universe. The range for this parameter is 0-15.

Filter Table filterdat - Available when using Packet Per Channel Format for Art-Net or sACN. Use the docked Table DAT to specify which net, subnet, universe channels are being received from.

Note: For sACN the first available universe has the index 1 as universe 0 is reserved by the system for future use.

Net Name netname - Specify the channel prefix for the net part of the address.

Subnet Name subnetname - Specify the channel prefix for the subnet part of the address.

Universe Name universename - Specify the channel prefix for the universe part of the address.

Start Codes startcodes - A list of accepted start codes when using sACN. If the DMX In CHOP receives an sACN packet with a start code not in the list then it will discard it.

Multicast multicast - Enable multicast for sACN. Multicast automatically builds the IP based on Net, Subnet, and Universe of the device. This allows for the DMX In CHOP to automatically receive from a sender without knowledge of it's address.

Queue Size queuesize - When using interface Art-Net or sACN, this will set the size of the incoming packets queue. This can be used to smooth data, though latency will be higher. In the case of Packet Per Channel (All), this parameter controls the maximum number of packets created per cook.

Rate rate - Resample the incoming data to this rate.

Parameters - Common Page

Time Slice timeslice - Turning this on forces the channels to be "Time Sliced". A Time Slice is the time between the last cook frame and the current cook frame.

Scope scope - To determine which channels get affected, some CHOPs use a Scope string on the Common page.

Sample Rate Match srselect - - Handle cases where multiple input CHOPs' sample rates are different. When Resampling occurs, the curves are interpolated according to the Interpolation Method Option, or "Linear" if the Interpolate Options are not available.

  • Resample At First Input's Rate first - Use rate of first input to resample others.
  • Resample At Maximum Rate max - Resample to the highest sample rate.
  • Resample At Minimum Rate min - Resample to the lowest sample rate.
  • Error If Rates Differ err - Doesn't accept conflicting sample rates.

Export Method exportmethod - - This will determine how to connect the CHOP channel to the parameter. Refer to the Export article for more information.

  • DAT Table by Index datindex - Uses the docked DAT table and references the channel via the index of the channel in the CHOP.
  • DAT Table by Name datname - Uses the docked DAT table and references the channel via the name of the channel in the CHOP.
  • Channel Name is Path:Parameter autoname - The channel is the full destination of where to export to, such has geo1/transform1:tx.

Export Root autoexportroot - This path points to the root node where all of the paths that exporting by Channel Name is Path:Parameter are relative to.

Export Table exporttable - The DAT used to hold the export information when using the DAT Table Export Methods (See above).

An Operator Family which operate on Channels (a series of numbers) which are used for animation, audio, mathematics, simulation, logic, UI construction, and many other applications.

Operators that have 1 or more input, like a Math CHOP, are called filters. See Generator.

An Operator Family that manipulates text strings: multi-line text or tables. Multi-line text is often a command Script, but can be any multi-line text. Tables are rows and columns of cells, each containing a text string.

A form of DATs (Data Operators) that is structured as rows and columns of text strings.

A Time Slice is the time from the last cook frame to the current cook frame. In CHOPs it is the set of short channels that only contain the CHOP channels' samples between the last and the current cook frame.

A parameter in most CHOPs that restricts which channels of that CHOP will be affected. Normally all channels of a CHOP are affected by the operator.

samples-per-second of a CHOP. Each CHOP in your network has a sample rate, whether it is used or not. The overall timeline has a "frame rate", which is the number of animation frames per second, generally your monitor display frequency.

Exporting is the connection of CHOP channels to parameters of operators. The output of each exporting CHOP is one or more channels, active only while the CHOP Viewer is on. The current value of a channel can be exported to a parameter of any operator, overriding that parameter's value. See Parameter.

The location of an operator within the TouchDesigner environment, for example, /geo1/torus1, a node called torus1 in a component called geo1. The path / is called Root. To refer instead to a filesystem folder, directory, disk file or http: address, see Folder.

Parameters in TouchDesigner are an operator's settings (numbers, menus, flags, strings, paths) which the user can alter. Parameters for any operator can be opened by right-clicking on the operator and selecting "Parameters..." A currently selected operator's parameters can be viewed in a Network Editor by pressing the keyboard shortcut 'p'.

TouchDesigner is a hierarchy of components. "root" is the top-most network in the hierarchy. The Path is simply /. A typical path is /project1/moviein1.
