Change log version K1220

Changes/Improvements:

  1. The largely revised Klick&Show App for Windows and MacOS now also allows software-based wireless transmission of laptop content in resolutions up to 4K @ 30Hz or 1080P @ 60Hz instead of the previous 1080P @ 30Hz for 1st generation Klick&Show base devices (K-FX, K-40, K-WM).
  2. Preparation of the K-FX and K-40 base units for use with future production batches of 4K transmitters, which require customized firmware drivers.

Bug fixes:

  1. Fixes the known error in K1215 that the LAN2 port no longer worked when using the "LAN infrastructure" network mode.
  2. Fixes a bug where in rare cases the transmission of content via native Google Cast protocol fails.

Known Errors:

  1. no entries.

Other:

  1. This firmware version represents a comprehensive upgrade with important improvements and is therefore recommended for all users.
    After installing the firmware, it is strongly recommended to perform a reset in order to correctly initialize the parameters of new functions.
    Existing transmitters should then be paired and further configuration carried out, and the App on user laptops should be updated.

  2. Display of the firmware version on the Home.
  3. Various minor changes and improvements.

Bug fixes:

  1. Fixes a bug where in very rare cases it was not possible to enter a customer-specific WiFi password in the WebUI.
  2. Fixes a bug where the error message "Error 121" was displayed when pairing a transmitter.
  3. Fixes a bug in which the simultaneous display of a customer-specific logo was also possible when using a customer-specific home screen.
    (Note: when using a customer-specific home screen, the display of a separate logo is not provided at the same time, as this area of the home screen is then reserved for displaying the QR code).
  4. Various minor bug fixes.

Known Errors:

  1. When using the "LAN infrastructure" network mode, the phenomenon occurs that the LAN2 port no longer works. As a temporary interim solution, we recommend continuing to use firmware K1213 if operation in "LAN infrastructure" network mode is absolutely necessary. A bug-fixed firmware will be provided shortly.
    If K-40 is operated in the factory "Accesspoint" network mode, the problem does not occur.

  2. Optimization of the home screen design with the introduction of a new Klick&Show icons, Klick&Show file names and redesigned pop-up notification windows.
  3. This firmware version ensures the compatibility of K-40 base devices with the Klick&Show 4K transmitters and is mandatory for their use.

    Button 1 ("-"): Switch between split and full screen display (in split mode),
    Button 2 ("="): Pause transmission (freeze).
    Both functions are also available when using the Klick&Show App .
  5. The "Pause transmission (freeze)" function, triggered either by the function button on the 4K transmitter or by the Klick&Show App, has been optimized and now overlays the access parameters at the top of the screen.
    This allows participants using either Klick&Show App or native protocols can be offered assistance and the parameters required for a connection, such as device name and PIN, can be briefly displayed.
  6. The link/URL displayed in the animated Klick&Show home screen to download the Klick/Show App ("KlickandShow.com/client") can now be customized if an administrator wishes to make the driver available at a different location (e.g. in the internal company network) and wants to display this accordingly on the home screen for users. Klick&Show driver at a different location (e.g. in the internal company network) and would like to display this accordingly on the home screen for the users.
  7. The options for using a customer-specific home screen have been extensively optimized. A loaded custom background can now also be displayed in full screen mode without the network status bar that was previously superimposed at the top of the screen. It is also possible to display the QR code for easy connection setup for mobile devices on a customer-specific home screen.
    (Note: a customer-specific individual logo can no longer be used in this situation).
  8. Even when using the digital signage function, the network status bar is no longer superimposed at the top of the screen and a full-screen display is shown, either with or without minimized access parameters.

Change log version K1204

Changes/Improvements:

  1. Completely new design of the Klick&Show user interface:
    The user interface of the Klick&Show product family has been completely redesigned and made more modern and intuitive, including the Home screen, the PC client for Windows and MacOS and the web menu interface.
  2. The Home screen can now be customized in a more flexible way, through:
    - individually loadable Home screen pages, whereby up to 2 individual pages are now automatically combined to form an animated Home screen,
    - a separately loadable customer logo,
    - an adjustable font color for the Home-screen status bar to enable a color design adapted to the loaded logo.
  3. Especially in the case of the K-40 base devices, the new home screen shows a dynamic behavior and only displays information on the use of the no longer available Klick&Show USB-A transmitters only if such a transmitter type is actually still being used and is paired with the base unit. This keeps the information on the home screen to a minimum.
  4. New digital signage function that automatically displays online content when the system is not in use for a meeting. Klick&Show system is not in use for a meeting. The digital signage function can be configured comprehensively with regard to URL (web address), display times, display days, type of display (full screen / with status bar).

  7. The web menu has been comprehensively expanded and now offers a "dashboard" at the admin level, which displays the most important configuration parameters at a glance, as well as a "setup wizard" that guides you step-by-step through the configuration during initial startup.
  8. When displaying several contents at the same time (split-screen function), the maximum number of contents (4, 3, 2 or 1) can now be defined in addition to the window layout. With only 1 content, a direct switchover takes place when a participant changes.
  9. In the security settings, the number of predefined security levels has been reduced from 3 to 2 for a better overview. As before, a "user-defined" setting of individual security parameters is possible as an additional option.
  10. Optimization of stability and performance for transmissions with Airplay.
  11. Preparation for the use of future Klick&Show transmitters with 4K resolution on K-40 base devices.

Bug fixes:

  1. Fixed a bug that prevented touchback via the client for MacOS. Klick&Show client for MacOS was not possible.
  2. Fixed a bug where the progress indicator displayed inaccurate values during a firmware update via the web interface.
