  • Factory default 5K EDIDs are available now.
    • Bugfix:
  • Resolved critical issue: Welcome Screen reliability. Fixed initialization errors, significantly improving Welcome Screen stability.
  • Resolved critical issue: Resolved rare cases where UCX units could freeze after a boot or restart cycle.
  • Resolved critical issue: Intermittent communication loss between Taurus TPX and HDMI TPX-RX Units.
  • Resolved critical issue: Support Package optimization: Improved resource usage during Support Package download.
  • Resolved a rare stability issue where UCX devices could, under specific conditions, enter a frozen state after approximately ten days of inactivity.
  • Fixed an RS232 serial port communication issue that caused a mismatched baud rate between UCX TPX/TPN devices and HDMI-RX pairs.
    • Known issue:
  • Firmware update recommendation: Before proceeding with the firmware update a restart/reboot cycle on the impacted devices are highly recommended.
  • Very rarely: Temporary video interruption: If a connection drop occurs between TPX-RX units, video transmission may pause for approximately 10 seconds during reinitialization. A preventive mechanism is already in place to protect the devices from the "Issue A".
    • v1.17.0b3
    Release date: 2025-07-31
    New feature:
  • Major LARA update: LARA 1.3.1 integration. LARA changelog is available on the LARA portal.
  • Remote System Logging functionality is available now under the V1/MANAGEMENT/LOG/REMOTE LW3 path.
  • New Buildroot version: 2025.02.
    • Known issue:
  • Known issue: Existing Intermittent Communication Loss Between Taurus TPX and HDMI TPX-RX Units In some deployments, a loss of communication has been observed between Taurus TPX transmitters and HDMI TPX-RX receivers after prolonged operation. This may result in temporary signal interruptions or device unresponsiveness. The issue is believed to be related to a low-level synchronization anomaly in the link layer between the transmitter and receiver. Workaround: A power cycle of the receiver typically restores operation. Changing the HDMI 5V Output settings to: "Auto" is also an available workaround. We recommend monitoring for updates, as a firmware fix is currently under development and will be included in an upcoming release.

  • Ethernet port P5 is counting TX Ethernet packets even if there is no connection. /MEDIA/ETHERNET/P5/COUNTERS.TxCounter Ethernet packet transmission on P5 is not affected by this issue. This Ethernet port works as expected other than the incorrect TX counter value.
  • If a USB Host without DisplayPort Alterante mode support is connected to one of the USB Type-C connectors, then the ActiveAltMode property erroneously reads as DP. /V1/MEDIA/USB/U1.ActiveAltMode=DP This issue causes Lightware Device Controller to erroneously display a yellow "DP" indicator on the port panel, which means the connection successfully entered DisplayPort Alterante mode. The following property describing the DisplayPort Alterante mode capability of the connected Host works as expected. /V1/MEDIA/USB/U1.HostSupportsDpAltMode=false USB and Displayport Data transmission is not affected.
  • An external control system using LW3 protocol subscribed to an HDMI output node OPEN /V1/MEDIA/VIDEO/O1 might not receive all CHG messages related to the presence of embedded audio on the output. For example if the video crosspoint switches beteen two sources: one with- and one without embedded audio, then the following CHG messages might be missing: CHG /V1/MEDIA/VIDEO/O1.EmbeddedAudioPresent=false CHG /V1/MEDIA/VIDEO/O1.EmbeddedAudioPresent=true Transmission of the embedded audio stream from input to output is unaffected. Muting the audio also works as expected.
