10.5. Endpoint Upgrade - Centralized Firmware Upgrade
The following instructions belong to the endpoint devices (UBEX-PRO20-HDMI-F100 / F110 / R100 series)
only. For the upgrading of the MMU see the
ATTENTION!
The centralized firmware upgrade feature is working from the installed MMU firmware v1.1.0
and endpoint firmware v1.3.1 and available for the later firmware package versions. The endpoint firmware
packages till v1.3.1 can be installed with LDU2 software - see the details in the
Method section.
10.5.1. Description
The centralized firmware upgrade method for the connected endpoint devices is the most comfortable way
to keep your devices up to date. The selected units can be updated together, the procedure is supervised
by the MMU, no user interaction is needed. During the firmware update, the AV transmission continues
smoothly in the unselected endpoint devices.
10.5.2. Technical Background
The centralized firmware upgrade for the endpoint devices is launched and controlled by the user and
supervised by the MMU. The firmware package of the endpoint devices is built in the firmware package
of the MMU which is installed when the MMU is upgraded. It follows that the firmware package versions
of the endpoints and the MMU are linked - see the list of the coupled firmware package versions in the
Endpoint Firmware Packages in the MMU
the centralized firmware upgrade method. The greatest advantage of the linked firmware packages is that they
are developed and tested together for the best user experience.
When the firmware upgrade is launched, the selected endpoint devices are set to bootload (firmware
upgrade) mode. The MMU sends the firmware package to the endpoints in multicast messages and repeats
it until all selected endpoints confirm the new firmware version.

INFO: The centralized firmware upgrade method requires the same network switch configuration
requirements as the AV signal transmission. See the details in the
The upgrade procedure can be launched by two ways as following:
▪ via Lightware Device Controller (LDC) software - see the detailed instructions in the
Upgrade - Detailed Instructions section (on the next page);
▪ via LW3 protocol commands - see the detailed instructions in the
Applied F-series endpoint firmware package: v1.5.4 | Applied R-series endpoint firmware package: v1.5.4 | Applied MMU firmware package: v1.3.3 | LDC software: v2.4.2b4

What If the MMU is Down during the Firmware Upgrade?
The MMU and the upgraded endpoint devices communicate with each other in the entire time of the firmware
upgrade. The MMU checks the status of all upgrading endpoints and streams the endpoint firmware package on
the network until all endpoints responds the completed status and to be claimed successfully. If the connection
is lost by the MMU with the endpoints for some reason, the upgrade procedure will be restarted automatically on
the endpoints which has not sent 'completed' status when the MMU is live on the network again.
What If the Firmware Upgrade is Failed on an Endpoint Device?
The endpoint device cannot be harmed in the case of firmware upgrade failure. The procedure can be
repeated/restarted anytime when it is necessary.
