Starting from the Dalitools V2 version, following the successive upgrades of the DALI standard, our software also continues to be upgraded. For long-term development considerations, the new version protocol needs to be changed. The Dalitools software after the protocol change no longer supports DLM-1 and DLGW-U controller sold before 2025. If you need to use the latest version of Dalitools software, you can do the following:

1. The model DLGW-U controller supports online firmware upgrade function, after upgrade  the firmware, the DLGW-U can be use with the Dalitools V2 and V1 versions .

2. The model DLM-1 controller does not support online firmware upgrade function. Products sold before 2025 cannot use Dalitools V2 software, only use Dalitools V1 software. The DLM-1 sold after 2025 supports the latest Dalitools V2 version software and is also compatible with Dalitools V1 version software.
