Fully DALI-2 certified test deviceWhat Problems Does ProbitSite Detect?
Built to diagnose the typical DALI faults you meet in the field. Use it for systematic troubleshooting in new and existing installations.
Why analysing DALI problems on the physical and electrical level is the only way to get comprehensive answers
Standard USB DALI dongles only see the logical protocol. ProbitSite analyses the physical layer: signal quality in percent and the precise timing of backframes. That is how you find hardware defects and wiring problems other tools simply ignore.
Typical USB DALI Dongle
Logical layer only
- Blind to electrical signal quality. Cannot tell a clean bus from a marginal one.
- No backframe timing analysis. Slow or out-of-spec replies stay invisible.
- Misses hardware defects, cable faults and bus loading issues.
- Not DALI-2 certified. No accredited test report you can hand over.
