Synchronous control system or asynchronous control system
Keywords: Synchronous control system, asynchronous control system
A suitable control system is crucial for led display. There mainly have 2 kinds of control system on market, one is synchronous and the other is asynchronous.
- Synchronous control system
Synchronous control system means the led display will show videos or images from computer or other input source, such as DVD, camera, TV, VCR, etc. directly.
When using synchronous control card, the led display need to always connect with a PC or video processor, when connection is cut off, the led display could not work normally.
Fast data transmission is one of advantage of synchronous control system; the led display will display programs from computer (or other input source) without any delay. Besides, it could transmit huge data volume, too.
Synchronous control system is mainly suitable for indoor and outdoor advertising display, stage rental using led display, sports led display, and studio led display, and so on.
- Asynchronous control system
Asynchronous control system indicates the led display will show programs asynchronous, the led display doesn’t need to always connect with a PC, it could work separately.
When using asynchronous control system, the programs will be edited on computer, then send to control card by UTP cat5, USB disk, Wifi wireless, 3G wireless or others. Once programs were sending to control card successfully, it will be saved on it. Then the end user could cut off connection between led display and PC
If the control PC is very far away from led display, asynchronous control system is a good choice. If the installation position is not convenient for wiring, asynchronous is a good solution, too.
Asynchronous control card is widely used for shop entrance led display, small size led sign, roadside led display, outdoor advertising player, etc.
