? ? The digital signal through the DVI interface is processed by the Data Processor into special data signals for the lighting system. The special data signals will be transmitted to the DDU which converts them into driving signals for the lighting fixtures accordingly. Features of the Data Processor are as follows: 1.DVI signal transferred to Joinmax network data, providing data signal source for lighting system. 2.Compatible with most video signal inputs, including DVI, DVD or any others video equipment outputs. 3.Maximum input resolution: 1680X1050 4.30 HZ or 60 HZ frequency is available, 60 HZ frequency can ensure better display. 5.Joinmax System (JMNET), standard network cable output interface based on 100MB Ethernet. 6.Maximum 80m long connecting distance to DDU. With single-mode optical cable, the distance can be extended to 10km. 7.Each DPU controls 131,072 pixels which can meet the needs for the control of most LED displays and lighting systems. 8.Additional DPUs can be connected in cascade to enhance system's driving capacity. The maximum cascaded quantity is 32. 9.Dot-matrix mapping function ensures the system control of irregular lighting distribution.
