Synchronous control
As the name implies, it means that the LED display screen will show what the computer shows.
The synchronized system is consisted of a sending card, receiving card and the relevant control software that will be installed on the computer.
The LED display screen and the computer can be connected when the sending card is put in the computer and the receiving card is installed in the screen, after that, you can edit the program with the software in the computer then send it via the sending card to the receiving card, next the receiving card will transfer the program to the screen automatically and lastly, the screen will broadcast the program.
That is to say, you need a computer working with the LED display screen all the time, once the computer does not work the LED display screen will stop working too.
Asynchronous control
Compared with the synchronized control system, the asynchronous control system is just the opposite.
It does not need a computer to work with the screens all the time because the sending card which has memory function.
Usually, it will be put in the cabinet and you can send a program to the sending card with a computer via ethernet cable, 3G, wifi, USB thumb drive.
It will be “uploaded” into the memory of the sending card.
After that, the program will be transferred to the receiving card and lastly, the screens will broadcast the program automatically.
In most cases, we recommend our customers choose the wifi router ( Within 10 meters ), to replace the ethernet cable with a wireless signal so that you get the greatest convenience to program the led display.
And for 4G/3G option, there is no distance limited, you could change the content on your screen in any place of the world as long as it has the internet.
Please note that there is the maximum resolution load capacity for asynchronous control way, it must below 23,00,000 pixels.
