This galvanically isolated port provides a connection to DALI (**Digital Addressable Lighting Interface**). The port does not provide a DALI power supply which must be ensured by an external DALI power source, e.g. [https://cue.atlassian.net/wiki/spaces/PRODUCTS/pages/489881770](https://cue.atlassian.net/wiki/spaces/PRODUCTS/pages/489881770) . DALI units are equipped with a diode bridge so that devices can be wired regardless of the cable polarity.  
DALI is a data protocol and transport mechanism that was jointly developed and specified by several manufacturers of lighting equipment. The DALI standard is specified in the **60929 IEC standard**. The DALI protocol allows for a maximum of **64 fittings** on a single network and the network can be divided into up to **16 different possible areas**.
