The same firmware update process applies using the IUI-SOL-ADAPTER, however for this update we also recommend the use of the new 'migrate' function through A-Link+. New locations and features added in the update may not populate to their correct default values if the migrate function, or a panel default, isn't performed.
The article linked below has some more information on updating to the latest version of A-Link+.
Latest release A-Link Plus software V6.3.11 29/05/2026
A-Link+ Migrate
The migrate function copies an existing panel profile to the latest firmware, and populates new locations to their correct default values.
From the customer selection screen, right click the profile you want to migrate and select 'Migrate Configuration to Latest FW'. This will create another customer profile with the same programming on the latest firmware version. Ensure the profile you migrate is up-to-date with what's currently programmed on the panel.

Once you've updated the panel, connect using the new profile and select 'Send A-Link+ Data to Panel'.
