BNC ports are typically used to connect workstations and coaxial cable connections, standard professional video equipment input and output ports. BNC cable has five connectors for receiving red, green, blue, horizontal sync and vertical sync signals. BNC connector is different from the ordinary 15-pin D-SUB special display interface standard connector. The R, G, B RGB signals and horizontal sync, vertical sync signal connector five independent components. Mainly used to connect workstations and other high scan frequency requirements of the system. BNC connectors can be isolated from the video input signal to reduce interference between the signal and the signal bandwidth than ordinary D-SUB Daquan color screen, can achieve the best signal response effect. RS232C serial ports: RS-232C standard (protocol) stands for EIA-RS-232C standard, which the EIA (Electronic Industry Association) on behalf of the American Electronics Industry Association, RS (Recommeded standard) represent recommended standard, 232 is an identification number, C for RS232 the latest in a modification (1969) Full Color manufacturer, before that, there RS232B, RS232A. . It provides for connecting cables and machinery, 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 the 232 hotel full color, RS232). Computer input and output interfaces, is the most common indoor full color serial interface, RS-232C interface has 25 standard gauge line, four data lines, 11 control lines, three timed line, seven backup and undefined line, Only nine commonly used, commonly used in the 25-pin D-sub port with a maximum transmission rate of 20kbps, cables up to 15 meters. RS232C port is used to control a computer signal input LED display. Shandong full color normal power supply can be divided into: switching power supply, power inverter, AC power supply, DC power supply, DC / DC power supply, communication power supply, power modules, power inverter, UPS power supply, EPS emergency power supply, purification power supply, PC power supply, rectifier power supplies, custom power supply, heating supply, welding power / arc power supply, electroplating power, network power supply, power supply operation, power adapters, linear power supply, power supply controller / drive, power supply, other common power supply, reverse variable power supply, power supply parameters, voltage supply, transformer power supply.
