Claim 9:
10. An LED driver for powering an LED light engine, the LED driver comprising:
a control terminal configured to be connected to a control terminal of the LED light engine;
a control unit connected to the control terminal of the LED driver, the control unit being configured to determine whether the control terminal of the LED light engine is a digital communication terminal or an analogue terminal by:
providing a communication signal to the control terminal of the LED light engine, and
establishing that the control terminal of the LED light engine is a communication terminal if a reply communication signal to the communication signal is received within a predetermined period;

wherein the control unit is further configured to:
if the control terminal of the LED light engine is a communication terminal, perform an initialization of the LED driver by exchanging configuration data between the LED driver and the LED light engine;
if the control terminal of the LED light engine is not a communication terminal, determining an impedance value observed at the control terminal of the LED light engine and performing an initialization of the LED driver based on the impedance value.
