    Connecting Fixtures Cabling The Brompton Tessera M2 processor can drive any Tessera compatible LED panel, mesh or batten system. Most panel products will have a panel controller card fitted inside each cabinet or tile. In the case of ray or batten type products where there is a low pixel count per fixture, the panel controller card may be housed in a buffer box and a number of fixtures connected to each buffer.

  • Page 38: Connection Guidelines

    The processor communicates with LED fixtures on the network using the Tessera protocol, which is transmitted via cabling that conforms to Cat 5e or above (this includes Neutrik etherCON terminations). The topology of a Tessera system is very simple. The fixtures just need to be connected to the processor either directly or via a Gigabit Ethernet network switch.

  • Page 39: Adding Fixtures To A Project

    Adding Fixtures to a Project The diagram below shows a typical system setup with some strings connected directly from the processor and some via a network switch. Each differently coloured group of panels represents one of the strings in the screenshot in the previous section. The red and green strings are connected directly to output ports 1 and 2 of the processor.

  • Page 40: Adding Fixtures From Network

    Adding Fixtures From Network Once the fixtures are physically connected to the network, the processor will auto-detect them (provided the fixture types were selected when the project was created) and the Add Fixtures From Network toolbar ("Add Fixtures From Network toolbar. " below) will turn green.

  • Page 41: Sub-Devices

    Sub-Devices Sub-devices are fixtures that have a smaller pixel count than traditional LED panels, and often have a different shape or format, such as LED strips. Sub-devices are connected to special controller boxes called Root Nodes which supply power and data to the Sub-devices and are sometimes referred to as PDU or Power and Data Units.
  • Page 42 Figure 5-8. A Root Node with unassociated Sub-devices To configure connected Root Nodes: select the relevant Root Node you wish to configure so that it is highlighted. Note that Sub-devices can be shown or hidden by selecting the Show Sub-devices button. Click on the Configure button to open the Configure Root Node dialog box.

  • Page 43: More About Topology And Associaton

    It is worth noting the system will limit the number of sub-devices according the maximum supported capacity of the Root Node. Please see the manufacturers documentation for further details on configuring specific Sub- devices. Figure 5-10. Associated Sub-devices More About Topology and Associaton The Tessera system uses the unique MAC address of each fixture to identify the order of the fixtures.

  • Page 61: Scaling And Cropping

    Any of the inputs may be used as a reference signal for genlock (See section "Genlock Settings" on page 92). Scaling and Cropping The Tessera M2 processor achieves scaling and cropping of the incoming feed by use of three settings in the input tab: Viewport, Zoom and Active Area. Viewport The Viewport settings define the region of interest of the incoming feed which is captured to the canvas.

  • Page 62: Active Area

    Figure 6-2. Incoming 1920x1080 video at its original size. If however you wish to capture only part of that incoming feed (perhaps because you then wish to expand the image to fill the canvas) you can set these values accordingly. For example, if you wished to capture a window of PAL content being displayed towards the bottom right corner of an HD feed you might set the Viewport to: Figure 6-3.
  • Page 63 Figure 6-4. The Geometry Tab Figure 6-5. The canvas with the Active Area shown by a dashed border. Having determined the region of interest to be captured from the incoming feed using the Viewport, that region can then be sized or moved to the appropriate part of the canvas. To set the Active Area to the same dimensions as the Viewport click the Snap to Viewport button.

  • Page 64: Snap Active Area To Selection

    Snap Active Area to Selection To automatically size the incoming image to fit on a particular group of fixtures, select the chosen fixtures and click the Snap to Selection button The Active Area will then be sized and positioned to fit over the selected fixtures. 4:3 and 16:9 The 4:3 and 16:9 buttons will automatically adjust the width parameter of the Active Area to the chosen ratio based on the height.

  • Page 65: Input Colour Control

    The aspect ratio of the Viewport is maintained with the Fill image scaled to fill the active area. The image is scaled to the exact dimensions of the active Stretch area without maintaining aspect ratio. Input Colour Control Black Level The black level control affects the base level of brightness of the darkest content in the incoming feed.

    brightness information intact or boost its colour to give a more colourful (perhaps too colourful) image. RGB Shadow In addition to being able to set a black level for a given input it is also possible to set the black level specifically for each of the primary colours in that input. These sliders, called RGB Shadow, equate to a setting for the black level of each specific colour.
  • Page 67 Figure 6-6. Test pattern showing colour bars at 75% and the corresponding Linear RGB histogram. The above picture shows a test pattern and its corresponding Linear RGB histogram. Note that there are clear columns at 75% for each of the three primaries. This is because all of the colours are either primary colours at 75% (red, green and blue sections) or secondary colours made from combinations of the primaries at 75% (cyan, yellow, magenta and white sections).

  • Page 68: Setting Colour Controls With The Aid Of Histograms

    The fact that the peaks corresponding to the black and white areas of the input image are located at the very start and end of each histogram indicates that this content source is well balanced and the full spectrum is being used. Setting Colour Controls with the Aid of Histograms The histograms can be useful in determining if a particular incoming signal is filling the entire spectrum of colour and brightness.
  • Page 69 Figure 6-10. Adjusting the contrast control will make brighter areas appear closer to the 100% threshold, assuming you have some areas of white content in your image and this is desirable. If specific colours do not appear to be rendering correctly you may wish to adjust the RGB Highlight and Shadow controls to work on that specific colour without affecting the other two primaries.

  • Page 70: Crossfading

    Crossfading Crossfading between inputs is achieved by storing the different inputs as presets with a crossfade time. To store presets to crossfade from one input to another follow these steps: 1. Select the input you wish to create a preset for (all tiles will change to this input). 2.

  • Page 73: Chapter 7 - Colour And Brightness

    Chapter 7 - Colour and Brightness There are four ways to modify the colour and brightness of fixtures connected to the Tessera system. Global colour - the controls on the Colour tab will affect all fixtures connected to the processor. Global Colour controls are located on the Colour tab to the right of the Main Project Screen.

  • Page 74: Rgb Gain

    value of the slider will be the value of the brightest fixture in the project, so in this example it would be 5000 Nits. Tip: If you wish to control the brightness of an array including different types of fixtures whilst maintaining them at a matching level then this is best achieved by leaving the brightness slider at default and modifying the intensity slider.
  • Page 75 Figure 7-1. Global Colour Override It is possible to remove single fixtures or groups of fixtures from the control of the Global Colour sliders and assign values to them separately. This functionality may be useful if you wish to maintain one whole screen at a constant brightness when there are fixtures grouped into separate screens on a processor.

  • Page 76: Chapter 8 - Presets

    Chapter 8 - Presets Presets Presets are a way of storing the settings that you make on the processor so that they can be recalled quickly and easily. These presets can be made to affect all the panels or a small selection of them depending on how they are grouped.

    For interlaced sources the latency is 2 fields for constant current fixtures and 3 fields for PWM driver fixtures. When fixtures that use constant current drivers are mixed with PWM fixtures then the processor adds a frame of latency on to the constant current driver fixtures to match the latency of the PWM fixtures.

    The On-Screen Colour Adjustment window displays the fixtures in the project as they are positioned on the canvas and has a toolbar that is particular to fixture colour and luminance adjustments. Fixtures can be selected the same way as on the Project Screen. Layers can be particularly helpful with selecting panels for OSCA adjustment.

  • Page 113: Seam Adjustment

    OSCA works in one of two modes: Seam Adjustment, which allows the luminance adjustment of fixtures and fixture modules, or Colour Adjustment which allows colour adjustment of fixtures or fixture modules. Seam Adjustment Seam adjustments allow the correction of luminance at the seams at the edges of fixtures or between adjacent modules within fixtures.
  • Page 114 Figure 11-12. OSCA on fixtures showing selected seams and cursor Once the desired seams have been selected then the luminance can be adjusted by clicking and dragging up or down on the Seam Adjustment Luminance thumbwheel. You can also hover the mouse pointer over the Luminance thumbwheel and use the scroll wheel on your mouse.
