1. Product introduction

LCD screen flippers are mainly used in various high-end conference halls, trading halls, advanced multimedia network systems, office furniture and private places. When the flippers are turned on, the LCD screen will automatically flip to an angle of 105 degrees (special requirements can also be designed separately) , The keyboard will also automatically rise to be flush with the desktop at the same time. When not in use, the display can automatically flip and hide inside the desktop. The product has functions such as anti-theft and dust-proof to keep the desktop flat and beautify the desktop.

The LCD display flipper newly developed and produced by our company overcomes the shortcomings of the previous flippers, such as unexquisite appearance, bulky body, and unstable flipping, and has been further transformed into a new generation with ultra-thin, ultra-quiet, exquisite and high-grade appearance, lightweight and flipping The stable display flipper is an excellent accessory equipment for furniture, which undoubtedly injects new highlights and vitality into the slightly dull furniture market today. It can be controlled manually, remotely and centrally.

4, Packing List

5, size description

6, control instructions

1. Single wireless remote control, one to one control.

2. Wireless remote control grouping control, up to five groups, multiple units grouping, one remote control operation method

3. When the power is turned on, press the "Pause" and "Up" buttons on the elevator panel at the same time for about 2 seconds, the indicator light in the machine will start to flash, and then press the code button 1 on the back of the remote control If the indicator light in the machine stops flashing, the code matching is successful. The machine can be controlled with the remote control. Repeat the above operation if unsuccessful.

4. 485 control method:

5. RS485 connection line:

6. Use an RS485 crossover cable (2-3-5 to 3-2-5) to connect the first LCD screen lifter with the central control 485 serial port; use RS485 direct connection between each LCD screen lifter (2- 3-5 pairs 2-3-5) can be connected in series.

7. RS485 port settings:

Baud rate 9600

Data length 8

Parity check N

Stop bit 1

Control protocol structure:

3F AA 00 CC DD EE FF 0D

AA: Internal command

00 is the internal command for individual control and address setting

01 is the group control command

02 is a random group control command

03 Input control commands for the keyboard

CC: Group address (0～9)

DD: Single independent address (0~255)

EE: Action command 0x44 up 0x22 down 0x32 stop 0x10 set address

FF: When random group control is used, this byte is the number of group control, that is, the number of bytes (1-64) after 0x0D. When the internal command is 0x03, this byte is the key value of the corresponding keyboard.

For example: 3F 03 00 00 00 00 00 01 0D This command is to send the number 1 to the elevator,

If you want to raise the elevator whose address is decimal 12, you must send

3F 03 00 00 00 00 01 0D

3F 03 00 00 00 00 02 0D

3F 03 00 00 00 44 00 0D

The time interval between every two instructions cannot exceed 5 seconds, if it exceeds, the issued instruction will be treated as invalid.

Turnover, lifter: RS232 direct connection, connect to 3.5 feet. RS485, pin 3 is connected to negative, pin 5 is connected to positive.

The baud rate is 9600, the data bit is 8bit, the parity bit is NONE, and the stop bit is 1bit.

Rising: FF 10 11 00 EE FF 10 11 00 EE FF 10 11 00 EE FF 10 11 00 EE FF 10 11 00 EE,

Stop: FF 10 11 00 CC FF 10 11 00 CC FF 10 11 00 CC FF 10 11 00 CC FF 10 11 00 CC,

Falling: FF 10 11 00 DD FF 10 11 00 DD FF 10 11 00 DD FF 10 11 00 DD FF 10 11 00 DD

8. Central control: Control through the RS485 port on the board and follow the above protocol.

Button control: divided into 5 buttons, backward, forward, stop, rise, fall

Backward: when the elevator rises to the top (after the upper limit travel switch is activated), press this key, the corner motor will rotate forward, and release the key to stop the corner motor; in the code matching mode, this key is the machine group address plus 1

Forward tilt: when the elevator rises to the top (after the upper limit travel switch is activated), press this key, the corner motor reverses, loosen the key, the corner motor stops; in the code matching mode, this key is the machine group address minus 1

Stop: When the corner motor or lifting motor is working, press this key to stop all motors; in the code matching mode, long press this key to launch the code matching mode and save the set address.

Rise: Press this key, the lifting motor will rotate forward, if the upper limit travel switch is activated, the corner motor will rotate forward; in the code matching mode, this key is the machine address plus 1

Down: Press this key, the lifting motor reverses, if the upper limit travel switch acts, the corner motor reverses; in the code matching mode, this key is the machine address minus 1

Combination key: press stop and up or down 4S to enter the address setting remote control code matching mode,
