At this stage, if updating the drivers and firmware haven’t help resolved the issue we would recommend testing different cables which are known to work with other ActivBoards such as the USB cable and PSU to see if this helps fix the issue. Please also bypass any wallboxes or connection panels in use to see if this helps.
