[0067] How to use:

[0068] I. Panel Button Functions

[0069] 1) Control functions can be achieved by pressing the touch button area on the control panel. Press the "Frequency Tuning" button to switch between different control channels; press the "Up" or "Down" button to raise or lower the blinds on the same channel; press the "Power On / Off" button to turn off the control panel.

[0070] 2) The Venetian blinds can be flipped by rotating the knob switch. Rotating clockwise or counterclockwise will flip the blinds up or down by a certain angle, thus flipping the slats.

[0071] 3) During the raising or lowering of the Venetian blinds, press the "Raise" or "Lower" button or slightly rotate the knob to stop the movement of the Venetian blinds.

[0072] 4) Perform a key pairing operation with the wireless signal receiver to achieve a wireless connection with a specific wireless signal receiver. Press the "Frequency Tuning" button to select a wireless connection channel, press the touch button on the control panel, the microprocessor on the main control circuit board runs the corresponding program, and transmits control signals through the wireless antenna. After the specific wireless signal receiver receives the control information, the wireless receiver runs the corresponding control function, thereby realizing the functions of raising, lowering, stopping, and flipping the venetian blinds.

[0073] 5) It can also perform button pairing with the wireless signal transmitter to achieve wireless connection. After receiving relevant control signals from the wireless transmitter, the microprocessor on the main control circuit board runs the corresponding program, and controls the motor rotation through the motor drive circuit of the main control circuit board assembly, thereby realizing the functions of raising, lowering, stopping and slat flipping of the venetian blinds.

[0074] The above-mentioned button operation instructions can be implemented by those skilled in the art through programming. This is a conventional technique, and the specific programming process will not be described in detail.

[0075] RS485 communication function

[0076] 485 communication requirements: Channel settings can be set from 0X00 to 0XFF, and channels can be controlled individually or in groups. A single channel can control 20 to 40 glass panels.

[0077] 485 communication control logic: When pairing with the receiver, after the receiver enters the pairing state, the 485 communication serial port outputs the pairing signal. If the motor reverses once in the forward or reverse direction, the pairing is successful.

[0078] The channel bits of 485 communication can be set to any address, with a maximum of 0xFF, and can be paired with the receiver.

[0079] Dry contact wiring function

[0080] Dry contact communication requirements: Single channel. Can control ≥ 320 glass panels, which can only move simultaneously. In dry contact communication mode, GND or the common terminal must be negative, and the other ports must be positive. Dry contact mode requires that on / off signals and high / low frequency signals are also available. It can be used with Huawei and other smart home devices. Default is high level; low level indicates a button is pressed.

[0081] Dry contact communication control logic: After the receiver enters the pairing state, press the pairing button briefly for 3 seconds. The motor will then reverse direction once more, indicating successful pairing. At this point, the system enters group control mode (the receiver supports learning group control codes). Pairing with the remote control is not required; the remote control and receiver are paired separately. Multiple photoelectric control boxes using dry contact functionality can be connected to a smart home system. Each box can be used individually when needed; group control requires a certain distance to prevent signal interference.

[0082] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles applied therein. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model based on the technical content disclosed in this application. However, such variations, as long as they do not depart from the spirit of this utility model, should be within the protection scope of this utility model. Furthermore, some terminology used in this specification and claims is not limiting, but merely for ease of description.
