Through the LCD control panel can set up parameters
(1) LED panel:FM board’s parameter display screen (2) To connect external transmitter board’s plug (3.3V,GND,RX,---- correspond to above picture(5) one by one .
(3) Control Keys:HD FM board parameters control keys(Up, down, left, right, OK)
First connect the antenna to the AV cables ,and then all the accessories connected well.
After power on,the transmitter LED display flash a few times, then become stable.
Long Press 2 seconds the "Menu" ,then where the place need to be changed will become to
deep black.Via pressing the up and down keys to adjust the figures.After finish it,
long press the Menu 1.5S to access locking and stability.
Control interface using simple instructions:
The LED board is composed of digital display and the three buttons. Specific Structured as shown in the above frame:display portion and key operation part.From left to right ,there are menu(LEFT_RIGHT), increase button (UP) and the decrease button (DOWN)
Pls properly connect the CONTROL_COM pin port of the full functional modulation module board to the CONTROL_COM pin port of LED control module board according to the correct identification,namely the two boards on the VDD/GND/TX/RX respectively corresponding to the connection
1.When LED display in the steady state,By the increase button(UP) or decrease button(DOWN) to select output frequency or RF bandwidth of the modified interface.
2.The menu(LEFT_RIGHT) can move the cursor from left to right cyclely;
First connect the antenna to the AV cables ,and then all the accessories connected well. After power on,the transmitter LED display flash a few times, then become stable. Long Press 2 seconds the "Menu" ,then where the place need to be changed will become to deep black.Via pressing the up and down keys to adjust the figures.After finish it,long press the Menu 1.5S to access locking and stability.
