First, outdoor LED display installation environment
LED outdoor display installation area is large, the design of its steel structure to consider the basis of wind, water, dust, moisture, ambient temperature, lightning, the surrounding population density and many other factors. Steel structure to be placed within the distribution cabinet, air conditioning, axial fan, lighting and other auxiliary equipment, but also a road, ladder and other maintenance facilities. The entire outdoor screen structure to meet the IP65 the following degree of protection.
Second, the power operation and instructions
Outdoor LED display installation using AC220V current supply, requiring grid voltage fluctuations less than 10%, and provide a good system grounding. Power supply by the fire, zero, ground three lines, power grid fluctuations less than 10%. The maximum power of the outdoor display screen is less than 10kw, the general requirements of the system single-phase voltage power supply, 10kw or more LED display, requiring three-phase five-wire voltage supply, and provide a good grounding system.
Third, the outdoor LED display hardware installation
The installation steps are as follows:
1, the DVI graphics card inserted in the motherboard AGP slot, install the card driver;
2, the data acquisition card inserted in the empty PCI slot;
3, with DVI cable to the data acquisition card and graphics card together;
4, the control line and serial port (Rs232) connected (optional);
5, with a cable connected with the receiving card;
6, the display shows the driver card and the hub with 50P flat line one by one corresponding to the connection;
7, check the connection can be set to correct or power debugging.
Fourth, the outdoor LED display installed software
1, led display graphics driver installation CD-ROM driver CD-ROM drive into the drive, you can automatically enter the installation state, please follow the prompts can be.
2, play the software outdoor LED display comes with a large screen dedicated play and set up software studio, or LEDSHOW4.0, to meet most of the big screen requirements, play picture text and VCD and so on.
5, outdoor LED display installation precautions
Wide audience, wide distance and wide, large ambient light changes, and may even be exposed to direct sunlight, to avoid the densely populated and crowded places to install, may lead to crowded. Insert the application software CD that came with the screen into the CD-ROM drive, copy or install all the programs to the computer. The system is controlled by the computer synchronization led display, through one or two super five 8-pin network cable communication. DVI master card and graphics card through the DVI cable connection, the computer through the RS232 serial line (one for the 9-pin serial port, the other end for the 4-bit crystal head), software can provide gamma correction, gray control, red and green data exchange, Control additional functions such as large-screen switch operation.
