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 big, 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 that, there 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 standard gauge line interface has 25 full-color manufacturers, four data lines, 11 control lines, three timing lines, seven alternate indoor and undefined line full color, commonly offer only nine full color, 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. Signal input communication distance is generally LED display computer or other device, the display device has an input signal from a distance, so they requested that the LED display must support the input signal and restore remote, almost all of the LED display supports 10 meters above the signal input. : LED display are usually used outdoors, so the requirements for outdoor LED display can adapt changing environment, anti-aging and trouble-free operation of other display devices to be slightly better than that. Normal fault-free time can reach more than 5000 hours. Full color manufacturers | Yasuhiro photovoltaic (certified) | Linyi full color provided by Linyi Wang Tai Electronics Limited.
