DVI input DVI interface is mainly used with a digital display computer graphics output function is connected to the computer's display RGB signals. DVI (Digital Visual Interface) digital display interface Full Color prices, by September 1998, at the Intel Developer Forum Digital Display Working Group established (Digital Display Working Group referred DDWG), developed by digital display interface standard. DVI digital signal terminals is better than a standard VGA terminal, a digital interface to ensure that the entire contents of the digital format for transmission to ensure the integrity of the host to monitor the transmission of data (interference-free signal is introduced), a sharper image can be obtained. BNC port typically used to connect workstations and coaxial cable, the standard of professional video equipment input and output ports. BNC cable has five connectors for receiving the red, green, blue, horizontal sync and vertical sync signals. Unlike ordinary 15-pin BNC connectors special display interface standard D-SUB connector. By R, G, B three primary color signals and the horizontal sync, vertical sync signal connector five independent components. Mainly used to connect workstations and other scanning frequency demanding systems. BNC connectors can be isolated from the video input signal to reduce interference between signals, and the signal bandwidth than ordinary D-SUB large full color led factory, can achieve the best signal response effect. RS232C serial interface: RS-232C standard (protocol) stands for EIA-RS-232C standard full color, including EIA (Electronic Industry Association) on behalf of the American Electronics Industry Association, RS (Recommeded standard) on behalf of the recommended standard, 232 is an identification number, C The latest was last modified on behalf of RS232 (1969), before full color manufacturers, RS232B, RS232A. . It provides for connecting cables and mechanical, electrical characteristics, functions and signal transmission process. Common physical standards also have EIARS-232-C, EIARS-422-A, EIARS-423A, EIARS-485. Here only EIARS-232-C (referred to as 232, RS232). Computer input and output interfaces, is the most common serial interface, RS-232C interface has 25 standard gauge lines, four data lines, 11 control lines, three timing lines, seven backup and undefined line, commonly only 9, commonly used in the 25-pin D-sub port with a maximum transmission rate of 20kbps, cable up to 15 meters. RS232C port is used for computer input signal to control the LED display. Indoor full color | Yasuhiro photovoltaic (certified) | Zaozhuang full color provided by Linyi Wang Tai Electronics Limited.
