AC-MXNET-CBOX-B/HA Firmware Updates

AC-MXNET-CBOX-HA ~ V4.28 ~ 05/30/2025

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.

V4.28
Feature Improvements:
  1. Modified the process of obtaining Dante IP Information to be compatible with FPGA version V9.19.4
  2. Added model name descriptors to MXNET MV41V2 endpoints.

V4.27
New Features:
  1. Added new MULTIVIEW page/tab, allowing control and support for the new AC-MXNET-1G-MV41V2.  For more information/configuration guides, please see this article here. Direct like to configuration guide here.
        

Version V4.26
  1. Updated SDDP broadcast information to be inline with control system certification requirements.

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.
