Release  - July 2026 

New features and functions: 

• Added integration with Biamp Workplace for cloud-based device management, configuration synchronization and remote firmware updates. 
• Added multicast DNS (mDNS) support to simplify device discovery on local networks. mDNS can be enabled or disabled in the MPX Management Console. 
• Added Secure Shell (SSH) support for advanced device administration and integration. SSH can be enabled or disabled in the MPX Management Console.  

Improvements: 

• Improved error handling when reading configuration values from the device.

Important update information 

When updating a device to version 1.3.0 or later, the device will automatically perform two consecutive firmware updates. 

The first update installs bridge firmware version 1.2.9, which updates internal device processes required by version 1.3.0 and later. After the bridge firmware has been installed, the device will automatically continue with the update to version 1.3.0. 

Do not disconnect power or interrupt the update process until both updates have been completed. 

• New: Biamp Workspace support 
• New: mDNS support 
• New: SSH support (see separate documentation) 

NOTE: Updating to 1.3.0 or later will automatically update the device two times. A bridge firmware (v1.2.9) is required to run to update internal processes that need to be in place for later versions to function. 

 

1.2.1  

March 2026

New features and functions 

• Lock active button when port is in use.  
•  Disable buttons when port is not connected.  
•  Possible to change power balancing mode between “Fair share” and “First come, first served”.  
•  Select port roles for user ports. This is an advanced setting that changes the way a connected user device communicates with the OMPX 250  
•  Turn off USB3 on passthrough-ports. This setting will only specifically disable the USB3 protocol, not USB as a whole.  
•  Turn off USB passthrough when no port is active. This setting will disable downstream equipment when no port is chosen. 

Improvements 

• Daisy-chain communication stability.  
• Automatic switching in daisy-chain topologies.  
• Video and USB stability and performance, including:   
  • User experience when connecting to Cisco video bars using USB-C.  
  • User experience when connecting to Lenovo Thinksmart Core Gen2 using USB-C.  
  • User experience when connecting to Neat Bar Gen2 using USB-C.  
  • User experience when connecting to Yealink A40 using USB-C.  
  • Video stability when using Apple MacBooks.  
  • USB3 stability when connecting device via USB-C pass-through ports.  
  • Better support for charging older HP and Dell laptops.  
• Support for connecting Windows MTR using USB-C to USB-C cable on UC port.  
• OTA Firmware update stability and performance.  
• Communication with MPX Management Console.  
• Laptop setup video to screen faster. Video setup duration depends on device model, screen and how switching is done:  
  • Up to 30% faster video setup sequence.  
  • Applies to all topologies (stand-alone, room kit, daisy-chain).  

Changes 

• Default power role on laptop ports is now DRP (Dual Role Port). This improves compatibility when connecting computers using a USB-C to USB-A cable.  

Fixes 

• Fixed an issue where USB error notifications appeared on laptops when using Windows UC configuration.  
• Fixed an issue where Administrator mode password was required, even if no password was set.  
• Fixed an issue where setting "Disable buttons for port" and "Disable port when it is not active" did not perform on a per-port basis.  
• Fixed an issue where MPX 250 and MPX 250 EXT LEDs did not show the correct state.  
• Fixed an issue where Mac M4 would restart when no screen was connected to the MPX 250.  
• Fixed an issue where in rare cases a device connected to port 4 would show a "ghost screen" when no port was active.  

Known issues 

• Disconnecting HDMI cable (on HDMI Only) while Mac M4 is connected on active port may cause the computer to restart.  
• Disconnecting HDMI cable (on HDMI Only) while Mac M1, M2 is connected on active port may give non-PnP video sharing.
