Abstract
The indoor and outdoor lighting industry has become the bigger and more systemized using the semiconductor LED with each control R(Red), G(Green), B(Blue). The communication standard DMX512(ANSI E1.11) protocol of it can control and perform max. 512 lightings, especially 170 lightings in 24 bit true color. As the performance of below 100 lightings is distinguished small-size, this paper proposes a bigger capacity lighting performance above 1,000 using connection to 1 master to 32 slaves. Also, this paper proposes the synchronization method in order to accomplish a designed performance. In proposed method, the master sends the synchronization signal to slaves every 400ms. Slaves receive this signal and use to initialize the timer becoming the basis of DMX512 output. The example of the developed products using proposed method and the operation is introduced.
