How to wire the 4 wires of led chandelier?

1, first strip the line, the end of each line are peeled head, 5 miles long enough. Then connect the wires, starting with the power supply. The wire end of the two-foot plug is connected to the 220V power connector of the 12V power supply, respectively connected to the L and N pins (do not distinguish), after connecting the power supply, a green indicator will be steady on.

2, Connect the point light source to the controller and 12V power supply, there is a current direction behind the point light source board (the power supply must follow the direction of the arrow, otherwise it will not be controlled or the point is not bright, or even burn the point light source), pin marking, such as the first pin +12V (connected to the positive electrode of the power supply), the second pin DAI (signal input) the third pin GND (connected to the negative electrode of the power supply). The +12V outlet connects to the positive terminal of the power supply, and the GND connects to the negative terminal of the power supply and the GND of the controller. The DAI signal line is connected to the controller DA/A, and if there are multiple lamp strings, it is good to follow the corresponding DA/A. The controller has 4 channels, OUT1, OUT2, OUT3, OUT4, in which each channel has 3 tracing lines, DA/A,CK/B,GND. The point light source of the series signal only needs to be connected to DA/A pin and GND pin (GND should be connected to the negative pole of the power supply). The parallel signal should be connected with 3 lines, and it is OK to connect according to the one-to-one correspondence of the electric board line of the lamp
3, wiring is completed, check, and then respectively 12V power plug and controller plug into the AC 220V plug board power can be through the program to show the light you want. Mission accomplished.
