    Tessera Processor Software 2.1.3

    5th December 2018
    2.1.3 Issue A
    Processor Firmware
    Tessera Remote
    Tessera Control

    Compatibility Note

    Panels upgraded to 1.5 firmware or later will not be discovered by or communicate with a processor running firmware 1.4.2 or earlier due to a protocol change. To downgrade these panels back to 1.4, use a processor running 1.4.3 or 1.4.4 to push firmware to them.

    Quick Association

    Quick association is a new, even faster way to associate large numbers of panels to your Brompton processor.

    • Each string is assigned a unique numeric code which will appear on the first panel of each string during association. Entering the numeric code on the processor (number keys or numpad) selects the corresponding string for association, the string is then ‘attached’ to the cursor for placement on the canvas.
    • Supported by all processors, in both remote and local UI
    • Supported only by R2-based panels with at least 64×64 pixels
    • Enabled by default when adding from network (unless in blind mode)
      • Can be toggled on/off by the toolbar button


    Closed Loop Redundancy for Tessera SX40

    Please observe the topology below to correctly configure your Tessera SX40 system for Closed Loop Redundancy.

    • Trunk pairs may be (independently) configured for redundant operation (A+B, C+D)
      • Load capacity for each redundant pair is the same as for a single non-redundant trunk
    • Symmetry must be maintained
      • XDs are mirrored on the backup trunk
      • Panel chains must be connected to the same port of the same XD on both primary and backup trunks
    • XD firmware must be updated for redundancy to function correctly

    Once the system has been cabled correctly, redundancy should be enabled for the ports which are cabled in this way under the Network tab in the processor as shown below:


    Custom Canvas Sizes for Tessera SX40

    The Tessera SX40 can now accept custom resolutions according to the following rules:

    • 720 <= width <= 4094
    • 720 <= height <= 4095
    • width * height <= 8847360
    • Width must be even
    • The Scaler will be disabled if a custom size is chosen ​

    Custom resolution settings should be thoroughly tested before being used in a production environment.


    Known Issues

    Restore factory defaults/format SD card can cause fixture library instability
    If you perform either of these operations please reboot your processor before browsing to the fixture library window as this may otherwise be unstable.​ ​

    Settings from Tessera Control are not applied to newly discovered fixtures
    If using Tessera Control to alter Brightness, Temperature or Gamma, these settings are not sent to newly discovered fixtures until a change is made to the value. ​ ​

    Tessera Remote and Tessera Control may not work on Mac OSX El Capitan
    When running on a Mac OSX El Capitan the Tessera Remote and Tessera Control applications can fail to detect network ports. This appears to be limited to cases where no default gateway is specified on the computer’s network interface.

    In situations where no default gateway is set using DHCP, we recommend specifying a default gateway manually. PCs running Windows and Macs running OSX Yosemite or earlier are not affected. ​ ​

    Tessera Remote may fail to import project files
    In some cases Tessera Remote may fail to import project files from local storage. As a workaround create the project from scratch, or use a local monitor, keyboard and mouse to import the project file before connecting with Tessera Remote. ​ ​

    Some input devices on KVM switches do not work
    We have had reports that trackpads may not function correctly when connected to the processor via a KVM switch. As a workaround we recommend using a mouse, or connecting input devices directly to the processor’s USB ports. ​ ​

    Monitors connected via DisplayPort-to-VGA adapters may be unstable
    Local user interface monitors connected to the processor via certian active DisplayPort-to-VGA adapters may give an unstable image or the monitor is not detected at all. As a workaround we recommend using a DVI or DisplayPort monitor.
