What are the synchronous and asynchronous system?


Synchronous: if the medium is synchronous, then the interaction that occurs takes place in real time. It means the LED display can show the same thing that appears on PC monitor. We have synchronous controller such as Novastar and Colorlight.

Asynchronous: communication is any transfer of information that is stored or archived and then later accessed. You can store the information into SD card or other storage media. Then take PC away, the program can play automatically. We normally use LYTEC for asynchronous controller.
