6. Interface Specifications

1. Signal indicator status and description: it will light up when operating the remote control; it will stay on after a successful Bluetooth/WIFI connection.
2. The 1-2 bits of the DIP switch are used to set the load output type, corresponding to the following:

RGB			RGBW			CCT			Single color
1	2	3	1	2	3	1	2	3	1	2	3
OFF	OFF	X	ON	OFF	X	OFF	ON	X	ON	ON	X

Note: After setting the load output type, the Bluetooth/WIFI control function needs to be reset, and the "add device" operation should be performed again in the APP. If the type is switched in the power-on state, the controller will automatically reset, and will directly enter the EZ distribution network state after the load light flashes quickly. For more connection instructions, please refer to the " Direction for use -Bluetooth/WIFI Network Operation" section.
3. Position 3 of the DIP switch is used to set the PWM frequency of the load output: OFF-2KHz (factory default), ON-15KHz.

PWM=2KHz			PWM=15KHz
1	2	3	1	2	3
X	X	OFF	X	X	ON

7. Bluetooth/WIFI Control Direction of using for SZ900-B1/SZ900-W1
Bluetooth/WIFI controlled by Tuya Application to achieve smart control like group control, scene control, timer control and so on.
Scan QR code from controller to download Tuya application and register it to get your home account.

Reading operation instruction of App, or following the pop-up prompt message with the APP, to finish the rest connection operation.
And compatible with voice control via Amazon Alexa, Google Assistant, Yandex Alice and so on.
Bluetooth/WIFI connection:
After connecting your phone to the network, please press and hold the "reset button" on the control for 5 seconds until the load light flashes, and then start the operation of adding smart devices in the graffiti app.
  
8. Typical Applications
Application Circuit 1: RGBW

 
Application Circuit 2: RGB

 Application Circuit 3: CCT

Application Circuit 4: Single color

 Application Circuit 5: wireless-sync diagram

Tips: Further distances or special environments can be used in conjunction with WP86-AP (RF 2.4G wireless signal amplifier) to expand signal coverage.
 
Application Circuit 6: wired-sync diagram

The high-quality wired synchronization function supports up to 50 dimmers (maximum distance is 80 meters between each 2 pcs) to work synchronously.
Tips: When transmitting for long distances, please prioritize using shielded network wires.
 
Application Circuit 4: integrated application
Wireless synchronization (application circuit 2) and wired synchronization (application circuit 3) can be mixed for use.
The first one in each group of wired synchronization is the host, and synchronization between the host and the host will be achieved through wireless means, ensuring that the distance between every two hosts does not exceed 10 meters.

Application Circuit 5: TUYA intelligent application (Bluetooth mesh/WIFI)

(TUYA-Bluetooth mesh: SZ900-B1)

(TUYA-WIFI: SZ900-W1)
Tips: Both Bluetooth/WIFI support integrated application with SZ900-Rx (RF version) through wired synchronization.
Notes:
1. The power supply voltage of the receiver is DC12V~24V, and should not be connected to a higher voltage. The input voltage of the power supply should be consistent with the voltage of the LED lamp;
2. Before powering on, ensure that the wiring is correct, avoid reverse connection of the positive and negative poles of the power input;
3. Set the PWM frequency as needed and pay attention to the corresponding maximum current value to avoid overload operation;
4. The diameter of the input and output connecting wires must be able to withstand the current of the corresponding lighting fixtures and ensure that the wiring is secure;
5. The receiver should be placed in a place with good heat dissipation and ventilation, which is beneficial for extending the lifespan of the product;
6. After the installation of the receiver, the code should be paired to avoid interference from external wireless signals;
7. Avoid live installation, or will may damage the receiver components;
8. In the autumn and winter seasons, it is necessary to install an electrostatic ring because human static electricity can reach thousands or even tens of thousands of volts, and low-voltage receivers may be damaged;
9. The product is not waterproof and should avoid moisture or rainwater entering the environment. If it needs to be installed outdoors, please use a waterproof box;
10. The warranty period of this product is 5 years, but does not include damage caused by improper human operation, severe damage or deformation of the product appearance, natural disasters, and damage caused by force majeure.
