Pharos Configuration

Version 1.15 by Alexander Mott on 2023/05/05 18:54

ShowRunner™ can control DMX fixtures through several different methods, including Pharos DMX controllers. The most common Pharos controllers sold through Crestron are the Pharos LPC-1 (DIN-DMX-1UNIVERSE) and the Pharos LPC-2 (DIN-DMX-2UNIVERSE). These LPC controllers appear physically identical, but the LPC-1 shares a single universe across both DMX outputs while the LPC-2 has a separate universe for each output. ShowRunner™ uses the Pharos Controller API to send commands over Ethernet to the Pharos Controller, which then sends DMX commands to the fixtures.

Pharos Project

Pharos projects are created using the free Pharos Designer 2 software from Pharos Controls. When creating a project for use with ShowRunner™, ensure that API version 5.0 is selected for the project. Individual loads control from ShowRunner™ is achieved with group-level commands using the Pharos Controller API, so each Fixture Group defined in the Pharos Project should correspond to a single load in ShowRunner™. In addition to group-level commands, ShowRunner™ also supports mapping ShowRunner™ Scenes to Pharos Timelines.

When creating a Pharos project for a ShowRunner™ installation, there are several things to consider:

  • Individual loads in ShowRunner™ send group-level commands to Fixture Groups in Pharos
  • Scene recalls in ShowRunner™ can be made to trigger Timelines in Pharos
  • The Pharos API limits group-level commands to intensity, intensity/RGB, and intensity/CCT
    • ShowRunner™ Load TypePharos API Command
      Single-ChannelIntensity
      RGBIntensity/RGB
      Dynamic WhiteIntensity/CCT
  • The Pharos controller does any necessary processing to adapt these commands for the fixtures
    • For example, 
  •  
  • ShowRunner™ uses group-level commands, so each individual load in ShowRunner™ must have a corresponding Fixture Group in Pharos
  • Fixture Groups defined as single-channel loads in ShowRunner™
  • For RGBW fixtures, it may be a good idea to define them as separate RGB and W fixtures so that ShowRunner™ is able to control the white channel separately from the RGB channels
  • Fixtures can belong to multiple Fixture Groups, allowing ShowRunner™ to send different types (e.g. RGB vs CCT) of command to the same fixture 
    • Useful for certain situations, such as HSIC fixtures that need to be controlled as color-changing (RGB) in some situations but dynamic white (intensity/CCT) in others

The basic steps for creating a Pharos Project for use with ShowRunner™ are:

  1. Open the Pharos Designer 2 software
  2. In the top-right, click "New Project" and select the type of Pharos controller that will be the primary controller
    • Crestron SKUs DIN-DMX-1UNIVERSE and DIN-DMX-2UNIVERSE both correspond to "LPC" in Pharos
  3. Navigate to the "Project" page by clicking the Pharos logo on the left
  4. Under the "Controller API" heading, verify that API Version 5.0 is selected
  5. Navigate to the "Network" page by clicking the network icon on the left
  6. Select "Controller 1" and verify that the number of universes in the "Properties" menu matches the controller that was ordered for the job
  7. If required, click the "New Controller..." button to add additional Pharos controllers
  8. Navigate to the "Layout" page by clicking the pencil and ruler icon on the left
  9. At the top left, click "Manage..." to edit the layout name and dimensions, modify grid settings, and upload a background image if desired
  10. Locate the desired fixture in the Fixture Profile List on the right side of the Layout page
    • Most fixtures can be controlled correctly using the generic single-channel, RGB, warm/cool, intensity/CCT, HSIC, etc. profiles
    • Pharos also has a large selection of manufacturer-specific profiles which can be used instead of the generics
    • Additional generic and manufacturer-specific profiles can be downloaded by clicking the cloud icon on the right, above the fixture profile list
  11. Add fixtures to the layout by dragging them from the fixture profile list
    • Every fixture that is added to the layout represents a unique set of DMX addresses 
    • The fixture number is different than the fixture address, and is automatically incremented by Pharos Designer 2
    • Fixture properties such as name, shape, and size can be edited
    • Right-clicking a fixture on the layout will allow you to either "Duplicate" or create a "New Instance" of a fixture
      • Duplicating a fixture creates a new fixture with the same profile and properties but that will occupy different DMX addresses
      • Creating a New Instance will create a new representation of the fixture without actually creating a new fixture; this allows you to have multiple fixtures represented on the layout that share the same DMX address

Note: Due to limitations with the API, only single channel, RGB, or Intensity/CCT load types can be defined in ShowRunner™. Other fixture types are controllable, but the types of command that ShowRunner™
