| New feature: |
|
New port properties
|
|
Welcome Screen, OCS and GPIO properties now available in LW3
|
|
UCX-4x2-HC30D variant is supported
|
|
Configuration cloning
|
|
Autoselect functionalities added to USB layer
|
| Bugfix: |
|
The following properties can be set to On or Off mode:
/V1/MEDIA/VIDEO/O1.Output5VMode
/V1/MEDIA/VIDEO/O2.Output5VMode
Auto mode will be available in a future 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.

|
No fading at the analog audio output during signal switching
|
|
VCONN is not supplied by USB Type-C interface of the product, if the port partner sends a Vconn Swap command via Power Delivery Protocol over the Communication Channel. USB Type-C active cables or VCONN powered peripherals require VCONN. These cables or peripherals won't work in the above case. Also communicating with e-Markers of cables will not be possible. Charging, USB and DisplayPort functions using passive cables is not affected. The product has a strong preference toward becoming a Power Source upon connecting a device. The product will source VBUS and VCONN most of the times, therefore Vconn Swap command would only result in the connected device sourcing the Vconn, and avoiding this issue.

|
Properties in /SYS node may change in future releases.
|
|
HPD signal is activated with up to 100ms delay compared to the 5V signal. This might cause compatibility issue with some devices.
|
|
If I1 input is selected by Autoselect after I5 input, the value of the following property might become invalid: /MEDIA/VIDEO/I1/HDCP.ActiveHdcpVersion The video transmission is not affected, only the displayed value of HDCP version is compromised.
|
|
Reporting the presence of embedded audio on the HDMI output is not reliable./MEDIA/VIDEO/O1.EmbeddedAudioPresent The property might read true while there is no embedded audio on the connected input port. Transmission of the embedded audio stream from input to output is unaffected. Muting the audio also works as expected.
|
| Known issue: |
|
Properties of Audio XP do not reflect the limitations of the video XP. If I5 is in use on the video layer, neither the video nor the audio content of I1 cannot be used.
|
|
Locked audio or video ports can be muted or unmuted.
|
|
192kHz multichannel audio is only delivered as stereo to the outputs. Lower sampling rates are not affected.
|
|
SwitchAll method cannot be used to disconnect all outputs. Switch method can be used instead. switchAll(0) method does not work. switch(0:O1;0:O2) works as expected.
