    • Bugfix:
  • Fixed a bug that resulted in wrong board information being displayed in LDC after a firmware upgrade,
  • Fixed a bug that resulted in wrong nominal voltage values being reported for the MX2M-AUX-DANTE-32CH board on the Health pages of the graphical user interface.
  • Fixed a bug that required to manually alter the secondary mini crosspoint on the output of an MX2M-AUX-DANTE-32CH when the main crosspoint was modified.
  • Fixed a bug that resulted in the matrix not being restarted after restoring the configuration.
  • Fixed a bug that resulted in invalid backup file being uploaded to the matrix switcher.
  • Fixed a bug that caused the embedded web and the LDC application to generate an invalid backup file.
  • Fixed a bug that resulted in escape backslashes being added to the channel labels with opening or closing brackets on an MX2M-AUX-DANTE-32CH board.
  • Fixed a bug that prevented the channel label on an MX2M-AUX-DANTE-32CH board from being updated through the graphical user interface.
  • Fixed a bug that prevented the restore operation issued through the graphical user interface from being completed.
  • Added the Switch to all command to input ports of the MX2M-AUX-DANTE-32CH board on the graphical user interface.
    • Known issue:
  • If the matrix switcher is set up to use dynamic IP address allocation through DHCP and a different IP address is assigned to it by the DHCP server when the lease is renewed, the matrix switcher remains accessible through both the old and the new IP address.
  • Factory resetting the individual ports does not work. Moreover, after factory resetting an individual board might not reset some parameters.
  • The update of MX2M-4OPTJ-IB and MX2M-4OPTJ-OB boards might fail if the optical cables are connected during the update process. Should this be the case, unplugging the optical cables and restarting the matrix resolves the problem and the update gets finished successfully.
  • For video signals having a width of 4096 pixels or more, the video format returned is invalid. Such video signals are passed through the matrix switcher without any problem, it is just the format indication that is invalid.
  • The information on the color space of the video signal arriving at the input port might not get propagated to the output port. This results in invalid color space information in the output video signal. Manually triggering a hotplug event on the input restores the valid color space information on the output.
    • v1.1.0b13
    Release date: 2021-02-15
    New feature:
  • From this version on, the matrix firmware supports the MX2M-AUX-DANTE-32CH board.
  • From this version on, CEC is supported by the video IO boards.
    • Bugfix:
  • Fixed a bug that caused some sink devices (displays) to fail to synchronize to the video stream if they are fed through an HDMI20-OPTJ-RX90 from an MX2M-4OPTJ-OB board.
  • Fixed a bug that caused some ports on the MX2M-4OPTJ-OB output board not to function correctly.
    • Known issue:
  • The channel labels of the input and output ports on the MX2M-AUX-DANTE-32CH board are not reset when the Dante device corresponding to the respective board is factory reset from the Dante Controller.
  • The matrix might report invalid link status for the Primary and Secondary interfaces on an MX2M-AUX-DANTE-32CH board.
  • It might happen, that after switching on and off the input signal many times the input port on a video input board erroneously reports a valid HDMI signal.
  • When changing the source for an output port on the MX2M-AUX-DANTE-32CH board, the secondary mini crosspoint on the respective output also has to be altered to get the audio content corresponding to the new source out from the board.
  • The manual showing the usage of PriLinkType and SecLinkType properties erroneously states that the accepted values are numbers. Use the strings corresponding to the values to set the link type.
  • After a firmware upgrade, wrong board information is displayed in LDC. Restarting LDC resolves the issue.
  • Wrong nominal voltage values are reported for the MX2M-AUX-DANTE-32CH board on the Health pages of the graphical user interface.
    • v1.0.0b33
    Release date: 2020-10-02
    Known issue:
  • Color space conversion to YCbCr 4:2:2 on the output might result in invalid picture if the color space format of the incoming video signal is 4:2:0.
  • The audio embedded by a video output board (e.g. MX2M-4HDMI20-OB) into the output HDMI stream cannot be decoded by a less error resilient player device (like a HDMI receiver). The same audio is played back seamlessly and without any problem by a regular television.
  • The audio cannot be de-embedded from the input video on an MX2M-4HDMI20-IB or MX2M-4OPTJ-IB board when the source of the input video is an output board and the respective output is set to embed audio from the Audio layer.
  • It might take an unusually long time for some sink devices (displays) to synchronize to the video stream if they are fed through an HDMI20-OPTJ-RX90 from an MX2M-4OPTJ-OB board.
  • The output video stream might contain wrong audio channels when zero or one channel is selected for embedding in the output video stream on video output boards.
  • Presets created via the front panel are displayed as audio presets on the embedded web and in the LDC application.
  • The audio input ports on an MX2M-AUX-8AUDIO board cannot be muted.
  • No video signal data are shown on the TPX output when the respective output is not connected to a compatible receiver.
