The most complete and simple LED display installat

The most complete and simplest LED display installation tutorial in history

led display screen, signal connecting line, power connecting line, system control card (loaded in the computer), system receiving card (loaded in the LED display screen), desktop computer (including DVI video output and serial port), display screen and related accessories

☆ use process

hardware installation steps are as follows:

1. Turn the DVI display into the ground state within 10-8 seconds and jump to a lower energy level. Insert the card into the AGP slot of the motherboard, and install the driver of the card

2. Insert the data acquisition card into the empty PCI slot (if used)

3. Connect the data acquisition card and the display card with DVI cable

4. Connect the control line to the serial port (RS232) (optional, required by lingxingyu system)

5. Connect with the receiving card by wire; (the specific number of pieces shall be based on the engineering drawings)

6. Set or power on debugging can be carried out after checking the connection is correct

the software installation steps are as follows:

1. Graphics card driver installation

insert the graphics card driver CD into the CD-ROM drive, and you can automatically enter the installation state. Please follow the prompts

first install directx8.1; Then install the driver; Finally, install the control panel

2. Playback software

install the large screen special playback and setting software that meets the national standard of experimental motor gas, led studio, or other control software

insert the application CD attached to the screen into the CD-ROM drive, copy or install all programs on the computer

☆ operation steps of electronic screen (important)

1. Screen opening: please turn on the computer first, and then turn on the electronic screen

connect the power supply to each equipment (ensure that the input voltage meets the product requirements)

turn on the LED screen (there will be a regional flash when the screen is powered on, indicating that the screen is powered on), turn on the computer, be sure to ensure that the graphics card is set correctly (if it is not correct, there will be no display, that is, a black screen), turn on the control software, and carry out basic tests like that. What are the application precautions and ordinary maintenance measures of the pendulum impact tester? Do you know? Plain size and display area settings (this setting does not affect the display of LED display screen)

2. Turn off the screen: first turn off the power supply of the LED screen, turn off the control software, and then turn off the computer correctly

☆ problems found

1. Check whether the wiring methods are correct, including the connection of the strong current part (the weak current part has been tested in the production enterprise), whether the signal connection is correct, mainly whether the input and output directions of the system receiving card are correct, and there is a directional diagram on the receiving card

whether the system connection is correct (please refer to the system connection instructions)

whether the computer software has been installed, including the setting of the graphics card (please refer to the setting instructions of the graphics card) and the installation of the control software

☆ precautions

1. Follow the operating steps in the user's manual

2. Moisture proof, humidity requirements: at the maximum working temperature, the LED display should be less than 92% of the relative humidity

3. The temperature is appropriate. The temperature requirements are: working environment temperature: -20 ℃ ≤ t ≤ 80 ℃

storage ambient temperature: -40 ℃ ≤ t ≤ 60 ℃

4. The damage tolerance and anti foreign object damage performance of power supply are greatly improved. The power supply should meet the requirements

the power supply voltage of LED display screen: 220V ± 10%; Frequency: 50Hz ± 5%

the safe ground contact is reliable, the ground wire and the zero wire are isolated reliably, and the power supply is connected away from high-power electrical equipment
