1. Strip the wire, strip each end of the wire, 5cm long enough.
2. Wiring, starting from the power supply, connect the two-pin plug to the 220V power connector of the 12V power supply and connect to the L and N pins respectively. After plugging in the power supply, a green indicator light will always be on.
3. Connect the point light source to the controller and the 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 able to control or light up, or even burn out the point light source), the line pins are marked, For example, the first pin +12V (connected to the positive pole of the power supply), the second pin DAI (signal input) and the third pin GND (connected to the negative pole of the power supply).
The +12V outlet wire is connected to the positive pole of the power supply, and GND is connected to the negative pole of the power supply and the GND of the controller. The DAI signal line is connected to the controller DA/A. If there are multiple light strings, just follow the corresponding DA/A. The controller has 4 channels, OUT1, 0UT2, OUT3, OUT4, each channel has 3 lines, DA/A, CK/B, GND.
The point light source of the series signal only needs to be connected to the DA/A pin and the GND pin (the GND must be connected to the negative pole of the power supply). Parallel signals need to be connected to all 3 wires, according to the electric board wire of the lamp-the corresponding connection is completed.
4. After the wiring is completed, check-down, and then insert the 12V power plug and the controller plug into the AC 220V plug-in board respectively, and then power on, and the desired light can be displayed through the program.
