AC-MXNET-CBOX-B/HA Firmware Updates

AC-MXNET-CBOX-HA ~ V4.25 ~ 04/10/2025

NOTE: If your CBOX is reading firmware with a version number of V2.XX, please navigate to this page here: https://support.avproedge.com/portal/en/kb/articles/ac-mxnet-cbox-firmware

Please update the CBOX first, before attempting updates on the endpoints. Using CBOX-B/HA Firmware V4.05 or above requires the following in order for RS-232 communication to function properly:
AC-MXNET-1G-D Decoders must be updated to V4.25/V4.28 or later.
AC-MXNET-1G-E Encoders must be updated to V3.44 or later.
AC-MXNET-1G-EWP Wall Plate Encoders must be updated to V1.10 or later.
AC-MXNET-1G-DANTE-E Encoders must be updated to V1.16 or later.
AC-MXNET-1G-EV2/EV2-B/EV2-C Encoders must be updated to V1.10/V2.04/V3.00 or later.
AC-MXNET-1G-DV2/DV2-B/DV2-C Decoders must be updated to V1.06/V2.02/V3.00 or later.

​If the physical HA Port of the CBOX-HA is desired to be utilized, please download the "IP-1G-CTL-004_Ver0.08.fwm" file from the below link, and upload the file in the same manner as uploading typical CBOX firmware.
Version V4.25

New Features:
  1. Added new High Availability feature, allowing two CBOX-HAs to be configured in a Primary/Backup function for redundancy purposes. For more information/configuration guides, please see this article here.

Bug Fixes & Improvements:
  1. Fixed a bug that caused the CBOX to repeatedly attempt to connect to the web GUI of any device using an APIPA address of 169.254.254.253.
  2. Fixed a bug that resulted in non-trunking configurations applied to an MXnet switchport to cause the Trunk Management page to behave unexpectedly.
Version V4.23
New Features:
  1. Added new System Monitoring software to the CBOX. This software will continuously check for a "pulse/heartbeat" of the web GUI services or the API server (port 24) for active communication. If communication fails 3 pulse checks, this monitoring software will automatically reboot the respective services, massively increasing long-term system stability/redundancy if a failure event occurs.
  1. Added new endpoint MCU Communication monitor. If the CBOX receives duplicated messages from the MCU of the endpoint within 1 seconds, the CBOX will ignore subsequent messages for 5 seconds after. If duplicated messages are still parsed after 5 seconds, the CBOX will suspend communication to the MCU of the specified endpoint. 
  2. Improved HDR metadata processing from MXnet 1G endpoints. 
  3. Added new page for Audio Return (ARC/eARC) routing for V2 devices.


  6. Modified the Configure -> Diagnostics web page. Advanced parameters can now be displayed per endpoint by clicking on the icon next to the endpoint's custom name, see below:



  7. The "Export Log" feature within the System Log page will now export all internal logfiles contained within the CBOX, into a .ZIP package.
Bug Fixes & Improvements:
  1. Fixed a bug where sending two video subscription change commands (matrix aset :v) simultaneously to a V2 decoder, and the new encoder is a different video resolution than the previously subscribed encoder (Ex. 4K -> 1080P, 1080P -> 4K), would result in video distortion on the decoder's output sink device. 
  2. Fixed the "Modules" page not populating the AVDM downmix preset options and V1-DANTE-E Dante parameters.
  3. Fixed a bug where AC-MXNET-1G-D endpoints with the internal model name of "AC-MXNET-1G-R" would cause the decoder firmware update selection window to not populate. 
  4. Fixed a parameter adjustment on V2 endpoints during the initialization/discovery process of the CBOX, that would cause V2-Decoders to restart. 
  5. Adjusted the location of the bandwidth and PoE columns within the Configure page.
  6. Fixed a bug where a logfile within the CBOX accumulates a large amount of repeated data.
Changelogs from past firmware iterations can be found in the attached Word document below.
