GVS DALI Driver NFC Tool is used to read the parameter information of DALI DT6 constant current dimming or DALI DT8 constant current color temperature adjustment driver. It can also be used to configure the driver parameters, such as: maximum/minimum brightness, gradient time/rate, short address/group, power-on brightness/color temperature, system failure brightness/color temperature, scene, target current, default coldest/warmest color temperature, color temperature step, physical coldest/warmest color temperature, dimming curve, minimum current compensation, minimum brightness calibration, CLO, DALI bus power supply status, etc.
