Firmware Release Notes
Below list shows the released firmware packages with important notes
v1.2.0b9
Release date: 2021-07-01
New feature:
▪
We recommend the update to the FW 1.2.0 only if you need some of the new features. The update will
cause Factory reset.
▪
Serial port is supported
▪
Status LED functions, IdentifyMe and Dark mode
▪
Special Push button functions (Enable HDCP, Factory Reset, Control Lock) are supported
▪
Serial over Ethernet is supported
▪
Basic IT security features (HTTPS, WSS) are available
▪
REST API is supported
▪
UCX-2x1-HC30 and UCX-2x2-H30 variants are supported
Known issue:
▪
UCX-2x1-HC30 and UCX-2x2-H30 are supported from FW 1.2.0. Uploading a FW package of version
less than 1.2.0 renders these variants disfunctional.
▪
No response to LW3 and REST API command SET V1/MANAGEMENT/LABEL.DeviceLabel
▪
IdentifyMe does not work in the LDC Device Discovery window. This function might not work in the
favourite devices list. (Next LDC version will solve this issue)
▪
LDC 2.5.10b1 version supports only 6107 TCP connection. If the 6107 port is closed the LDC cannot
connect to the device. If Device Discovery detects a product with 6107 port closed then it will ask for
permission to open it. This function might not work in the favourite devices list. Next LDC version will
be able to connect using WSS (443).
▪
Crosspoint view of the LDC only reflects the crosspoint mute property (/V1/MEDIA/AUDIO/XP/O1.Mute)
but it won't show Embedded audio mute state of the port (/V1/MEDIA/VIDEO/O1.EmbeddedAudioMute)
▪
Network settings of the device (like IP address) can be changed via LDC device discovery window.
Changes take effect as expected but the displayed value of these properties follows the changes only
after rebooting the device.
▪
It is not possible to clone configurations between different variants but the error message might be
missing
v1.1.1b1
Release date: 2021-04-19
Bugfix:
▪
Fixed DP Alternate mode interoperability issues with various kinds of USB Type-C devices
v1.1.0b7
Release date: 2021-03-04
New feature:
▪
Welcome Screen, OCS and GPIO properties now available in LW3
▪
Autoselect functionalities added to USB layer
▪
UCX-4x2-HC30D variant is supported
▪
Configuration cloning
▪
New port properties
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.
