Release notes for HDMI-TPX-100

v2.9.0b1
Release date: 2026-04-30
New feature:
Added RX-side VLAN management for TPX/TPN systems, including configurable VLAN ports, management-network support, parallel IP addressing, and trunk-mode operation.
Bugfix:
Fixed a critical issue that could occur when a UCX TPX TX updated the firmware of a connected HDMI-UCX-TPX-RX107.

v2.8.0b8
Release date: 2026-03-04
New feature:
New -V2 variants are supported.
Bugfix:
ICRON's USB2.0 ASIC firmware updated to version N18, adding further stabilization to the 10G USB data transmission.
Stable connection with Samsung Flip if PIP Capture is turned on.
Semtech's AVX SDVoE firmware has been update to version v2.3.0.8 adding further stabilization to the 10G fee.
Known issue:
LW2 command {heap} gives invalid value.
In rare cases, restart time of devices could increase up to 30 seconds.
There is a ~0.3% chance, that an EDID-change on TPX-RX will not take effect in TPX-TX input. Video transfer is possible in this state, but the resolution might be incorrect.

v2.6.1b1
Release date: 2025-09-15
New feature:
From this version on, extenders with Dante audio capabilities are also supported: HDMI-TPX-TX107D, HDMI-TPX-RX107D, HDMI-TPX-TX209DU2K, HDMI-TPX-RX109DU2K.
Bugfix:
HDMI stream starts with every BlueRiver control server version.
TX-RX communication failures are fixed by AVX FW updated to 2.3.0.5
AUDIOMUTE LW2 command only accepts valid arguments.

v2.5.2b2
Release date: 2024-01-24
New feature:
From this version on, the copper based scaling receivers (HDMI-TPX-RX107A-SR and HDMI-TPX-RX107AU2K-SR) are also supported.
Bugfix:
Improved on the quality of the link between the TX and the RX devices. This has a positive effect both on the RS232 and the Ethernet communication.
Known issue:
When a scaling receiver is connected to a transmitter in point-to-point mode, the image output may become unstable if, the receiver is in fast switch mode and the embedded audio is set to 192 kHz and 24-bit.
RS232 settings are not reset properly on the TX device after a factory reset when more than one SDVoE Control Server is present on the network.
Factory resetting the RX device causes the established USB KVM connection not to work anymore. Restarting either the transmitter or the receiver resolves the problem.

v2.5.0b8
Release date: 2024-06-19
New feature:
From this version on, the copper based scaling receivers (HDMI-TPN-RX107A-SR and HDMI-TPN-RX107AU2K-SR) are also supported.
Bugfix:
Fixed a bug that caused a 422 10bit input signals to be converted to 422 8bit during transmission.
Fixed a bug that caused the de-embedded audio to be muted on the analog audio output when a display with DVI EDID is connected to the local output of the transmitter device.
From this version on, the HDCP is reported as not supported towards a source connected to a TX device when the supported HDCP version of the sink connected to the RX unit cannot be determined.
Fixed a bug that caused the video signal on the HDMI output of a receiver device to disappear when the HDMI cable to a sink device is disconnected and connected again.
Known issue:
Factory resetting either the TX or the RX device causes the established USB2.0 connection not to work anymore. Unplugging and replugging the corresponding USB device or restarting either the transmitter or the receiver resolves the problem.

v2.4.0b8
Release date: 2023-11-08
New feature:
From this version on, the health status of the receiver can be queried and the analog audio volume can be set from a compatible transmitter device.
Bugfix:
Fixed a bug that caused the USB2.0 output not to function after updating the HDMI-TPX-TX and HDMI-TPX-RX pair.
Fixed a bug that caused a video with color depth of 10 or 12 bit/component to be converted to 8 bit/component.
Fixed a bug that resulted in muted audio on the analog output after a factory reset (e.g., during firmware upgrade).
Fixed a bug that caused the USB2.0 and Ethernet transmission to stop intermittently when switching between HDMI1.4 and HDMI2.0 video signals on the input of the transmitter.
Known issue:
A clicking sound can be heard in the analog audio output of a receiver device when the format of the input HDMI stream changes.
A clicking sound can be heard in the analog audio output when the audio content in the incoming HDMI stream changes from compressed audio to uncompressed audio or vice versa.

v2.3.0b15
Release date: 2023-09-28
Known issue:
When switching between HDMI1.4 and HDMI2.0 video signals on the input of the transmitter, the USB2.0 and Ethernet transmission intermittently drops. USB HID is not affected.
When updating the HDMI-TPX-TX and HDMI-TPX-RX pair, it might happen that the USB2.0 output stops functioning. Restarting the RX and the TX devices resolves the problem.
When a dispay with DVI EDID is connected to the local output of the HDMI-TPX-TX transmitter, the de-embedded audio is muted on the analog audio output.
422 10bit signals are converted to 422 8bit during transmission.

v2.2.0b5
Release date: 2023-07-27
New feature:
From this version on, the HDMI-UCX-TPX-RX107 product variant is also supported.
Bugfix:
Fixed a bug that could have resulted in intermittent drop outs of the transmitted audio content on the output for a brief period of time.
Fixed a bug that potentially could cause a crash on the receiver if the video reception was unstable.
Known issue:
Video with a color depth of 10 or 12 bit/component is converted to 8 bit/component. Consequently, Dolby Vision and HDR is not supported.
Factory resetting the device mutes the audio on the analog output. A power cycle restores audio de-embedding to the analog output.

v1.3.0b3
Release date: 2023-03-31
Bugfix:
Fixed a bug that caused the HDCP encryption on the local output of the HDMI-TPX-TX209AK device not to work properly.
Fixed a bug that caused the secondary video output of the HDMI-TPX-RX209AK not to work.

v1.2.0b7
Release date: 2022-12-15
Bugfix:
Fixed a bug that caused the HDCP capability information not to be transparently passed from the sink on a decoder to the source on the encoder.
Known issue:
For resolutions with a pixel clock just above the 340MHz limit, scrambling and TMDS bit clock ratio are not adjusted as required by the HDMI 2.0 specification.

v1.1.0b4
Release date: 2022-04-08
New feature:
From this version on, the HDMI-TPX-TX106A, the HDMI-TPX-TX209AK, and the HDMI-TPX-RX209AK product variants are also supported.
Bugfix:
Changed the default RS232 configuration parameters to 9600 Baud, 8 data bits, no parity, 1 stop bit.
Known issue:
The local output on a HDMI-TPX-TX209AK device is disabled.
The secondary video output (HDMI OUTPUT 2) of the HDMI-TPX-RX209AK is disabled.
When the audio content in the HDMI input stream is changed from LPCM to any compressed format, the compressed audio briefly (for less than 0.1s) appears on the analog audio output.

v1.0.1b2
Release date: 2021-12-10
Bugfix:
Fixed a bug that resulted in infinite attempt to read EDID on the output if the EDID checksum is wrong.
Fixed a bug that caused the receiver to output 4kp60 signal only if the connected sink had an EDID with 4kp60 support.
Known issue:
The learn EDID feature does not work if no signal source is connected to a HDMI-TPX-TX106/107 transmitter device.
For certain HDMI timings (R2560x1600_75Hz, R2560x1600_75Hz, R2560x2048CVT60Hz, R2560x2048CVT60Hz, R1080p100B, R1080p100B, R2560x1600_60Hz, and R2560x1600_60Hz) the HDR content is truncated to 8bit per component on the output.
There might be intermittent drop outs of the transmitted audio content on the output for a brief period of time. These are more likely to occur for LPCM content.
The VIDEO_STATUS LED does not work on the HDMI-TPX-RX106/107 devices.

v1.0.0b9
Release date: 2021-11-10
Known issue:
4kp60 signal is output from the receiver only if the connected sink has an EDID with 4kp60 support.
When connected to the receiver, sinks without HDCP 2.2 support will not display content that could otherwise be output using HDCP 1.x. (I.e., signal with content type of Type 0 will not be displayed on such sinks.)
CEC commands have to be issued twice to pass through the transmitter - receiver device pair.
The VIDEO SIGNAL LED does not work.
