DVI master card and graphics card via DVI cable to connect between the computer via RS232 serial line (a 9-pin serial port, the other end of four crystal head), can software provides γ correction, gradation control, red and green data exchange, control the big screen switching operation and other additional features.
Second, the supply operation and description
LED display with AC220V current power supply, voltage fluctuations requires less than 10%, and provide a good system ground. Powered by the fire, zero to three lines, power fluctuation is less than 10%.
LED display full-screen maximum power is less than 10kw, generally requires a system of single-phase voltage power supply, 10kw or more LED display, require three-phase five-wire voltage power supply, and provide a good grounding system.
Three, LED display hardware installation
Installation steps are as follows:
1, the DVI display card into the AGP slot on the motherboard, install the card driver;
2, the data acquisition card inserted in the empty PCI slot;
3, using the DVI cable to the data acquisition card and graphics card connected together;
4, the control lines and serial (Rs232) is connected (optional);
5, with a network cable connected to the receiver card;
6, LED display driver card and hub plate correspond with 50P flat cable connected;
7, check the connection to be set correctly or power debugging.
Four, LED display software installation
1, LED display graphics driver installation
The graphics driver CD into the CD-ROM drive, you can automatically enter the installation state, according to the prompts.
2, playback software
LED display comes with a large screen play and setup software LED studio, or LEDSHOW4.0, can meet most of the requirements led the big screen, play pictures, text and VCD.
Will vary with the screen attached to the application software CD into the CD-ROM drive, copy or install all the programs on your computer.
