Set 1, Set 2	The detected devices from the list of detected devices (LDS) can be projected for protected mode by short-circuiting the two set inputs. This corresponds to the functionality of parameter 0x108 (command interface), if the value 0x0210 is entered there.

Since the user data are modulated on the power supply line with the AS-Interface, a special AS-i power supply unit (30.5 V_DC) is required. You can

use the KL9528 AS-i power supply terminal with integrated data decoupling or
the KL9520 AS-i potential feed terminal in conjunction with a standard power supply units.
