What is the IP protection rating of the LED display? Next, the Fuxin caster procurement platform introduces everyone: The IP protection level is composed of two digits. The first digit indicates the level of the lamp from dust and foreign objects. The second digit indicates that the lamp is moisture-proof and waterproof. The degree of airtightness, the larger the number, the higher the degree of protection.
See product design and component selection through inspection and certification
As one of the most promising high-tech industries in the 21st century, LED has received much attention in product design, development, application and testing. Although the detection and certification of LED products is the last step in the market, it has important guiding significance for the product design stage. Reasonable product design can enhance product reliability, reduce EMC problems, and pass product testing and certification faster, laying the foundation for the product to win the market and the long-term development of the company.
System troubleshooting - eight steps to troubleshoot LED display system failure
Step 1: Check if the graphics card settings section is set. If necessary, set the method in the CD electronic file, please refer to it.
Step 2: Check the basic connection of the system, such as DVI cable, whether the network cable socket is correct, the connection between the main control card and the computer PCI plug, the serial cable connection, etc. The connection method has a legend, please refer to the reference carefully.
Step 3: Check if the computer and LED power system meet the usage requirements. When the power of the LED screen is insufficient, when it is close to white (more power consumption), it will cause the screen to flicker, and prepare a suitable power supply according to the power requirements of the cabinet.
Step 4: Check if the green light of the sending card flashes regularly, flashing to step 6. If it is not flashing, restart it. Check if the green light flashes regularly before entering win98/2k/xp, such as blinking to the second step. Please check if the DVI cable connection is connected. If the problem is not solved, one of the sending card, the graphics card and the DV cable I is faulty. Please repeat step 3 after replacing.
Step 5: Please follow the software instructions to set or re-install and then set, until the green light of the sending card flashes, otherwise repeat step 3.
Step 6: Check if the green light (data light) of the receiving card flashes synchronously with the green light of the sending card. If it flashes to step 8, check if the red light (power) is on. If it turns on the seventh step, it does not light up to check the yellow light (power supply). Protection) Is it bright, if it is not lit, check if the power supply is reversed or the power supply has no output. If it is bright, check if the power supply voltage is 5V. If the power is turned off, remove the adapter card and cable and try again. If the problem is not solved, the receiving card is faulty. , replace the receiving card, repeat step 6.
Step 7: Check if the network cable is connected well or too long (must use the standard Super Category 5 network cable, the longest distance of the network cable without repeater is 100 meters), check whether the network cable is made according to the standard (please refer to the installation and setting) If the problem is not resolved, the receiving card is faulty, replace the receiving card, and repeat step 6.
Step 8: Check if the large screen power light is on. If it is not on, go to step 7 and check if the adapter card interface definition line matches the unit board.
Note: After most screens are connected, there may be no screen or flower screen in a certain box. Because the RJ45 interface of the network cable is not securely connected, or the receiving card power is not connected, the signal is not transmitted, so please re-plug it. The network cable (or swap), or plug in the receiving card power (pay attention to the direction) can solve the problem.
Label: What is the IP protection rating of the LED display?
Power management system monitors the electrical distribution system, typically providing data on overall and specific power consumption, power quality, and event alarms. Based on that data the system can assist in defining, and even initiating, schemes to reduce power consumption and power costs.
