Outdoor LED display installation six ideas 1. Lightning protection devices are installed on display screens and buildings.
The main body of the display screen and the casing are well grounded, and the grounding resistance is less than 3 ohms, so that the large current caused by the lightning discharges in time; the display screen may be subject to strong electromagnetic attacks caused by lightning. Waterproof measures of the LED display itself and the joint between the screen and the building must be strictly waterproof and leakproof; the screen should have good drainage measures, and can be discharged smoothly in case of water accumulation; pay attention to waterproof and moisture proof. The display screen is installed outdoors, often exposed to the sun, rain, dust, and the working environment is harsh. If the electronic device is wetted or severely dampened, it will cause a short circuit or even a fire, causing a malfunction or even a fire, resulting in loss;
3. The circuit chip selects and selects the industrial grade integrated circuit chip whose working temperature is between -40°C and 80°C, prevents the winter temperature from being too low to make the display screen unable to start.
4. Installation of ventilation equipment cooling, so that the internal temperature of the screen between -10 °C ~ 40 °C.
Axial fans are installed above the screen body to discharge heat; the display screen itself generates a certain amount of heat. If the ambient temperature is too high and the heat dissipation is poor, the integrated circuit may not work properly, or even be burned, and the display system may not function properly. jobs;
5. Super high-brightness light-emitting diodes must be selected in order to ensure long-distance visibility in the presence of strong ambient light. Ultra-high-brightness light-emitting diodes must be used. Increased contrast, wide viewing area, wide line-of-sight requirements, and wide field of vision require large variations in ambient light. In particular, it may be exposed to direct sunlight.
6. The display medium adopts a new wide viewing angle tube with a wide viewing angle, pure color, consistent coordination, and an outer packaging life of over 100,000 hours. The outer packaging of the display medium is currently the most popular covered square tube, sealed with silicone, and no metal assembly; its exquisite appearance Beautiful, sturdy and durable, with features of protection against direct sunlight, dust, water, high temperature, and short circuits.
Outdoor LED electronic display installation considerations related to the future use and safety of the product must be treated with strict treatment.
Led display how to debug 01. What could be the cause of the load?
Failure to load may be due to the following reasons: Please check against your actions according to the listed items:
A. Make sure the control system hardware is properly powered up. (+5V)
B. Check and confirm that the serial cable used to connect to the controller is a straight line, not a crossover cable.
C. Check that the serial port cable is intact and that neither end is loose or missing.
D. Compare the LED display control software with the control card of your choice to select the correct product model, the correct transmission method, the correct serial port number, the correct baud rate, and correctly set the control system hardware against the DIP switch diagram provided in the software. The address bit and baud rate.
E. Check if the jumper cap is loose or loose; if the jumper cap is not loose, make sure the jumper cap is in the correct direction.
F. If after the above checks and correction still occurs after loading, please use a multimeter to measure if the serial port of the connected computer or control system hardware is damaged. To confirm whether the computer manufacturer should be returned or return the control system hardware to the test.
02. What could be the cause of the lack of communication?
The communication is not the same as the reason of not being loaded, it may be due to the following reasons, please compare with your operations according to the listed items: how to debug the led display + led display debugging method + electronic screen installation Commissioning A. Make sure the control system hardware is properly powered up. (+5V)
B. Check and confirm that the serial cable used to connect to the controller is a straight line, not a crossover cable.
C. Check that the serial port cable is intact and that neither end is loose or missing.
D. Compare the LED display control software with the control card of your choice to select the correct product model, the correct transmission method, the correct serial port number, the correct baud rate, and correctly set the control system hardware against the DIP switch diagram provided in the software. The address bit and baud rate.
E. Check if the jumper cap is loose or loose; if the jumper cap is not loose, make sure the jumper cap is in the correct direction.
F. If after the above checks and correction still occurs after loading, please use a multimeter to measure if the serial port of the connected computer or control system hardware is damaged. To confirm whether the computer manufacturer should be returned or return the control system hardware to the test.
03. Why does the system prompt "Please connect the LED display controller"?
Many customers and friends directly download the "LED display control system" from the "Download Center" on the company's website. After installing for 20 minutes, the message "Please connect the LED display controller" will appear. This is due to the system The reason why the open control system hardware was not detected during the test period.
At this time, please connect one end of the LED display control system hardware you purchased to the computer and the other end to the HUB distribution board. The HUB distribution board's cable socket is connected to the interface of each unit of the LED display.
After the connection is complete, you can go to the "settings" in the "setting screen parameters" set the relevant parameters, complete and then close again after opening the software, then the software will appear above the "connection is successful" words. At this point, the system has detected the display control system hardware and can be used without time constraints.
04. Why does the outdoor LED display control system hardware have a few seconds of bright lines or “screens†when it is just powered up?
After properly connecting the display controller with the computer and HUB distribution board and display, it is necessary to provide the controller with +5V power for normal operation (in this case, do not directly connect with the 220V voltage). At the moment of power-on, there will be a few seconds of bright lines or “huaping†on the display screen. The bright line or “huaping†is a normal test phenomenon to remind the user that the display is about to start normal work.

LED display installation and debugging methods
For outdoor LED display, because it is used outdoors. Therefore, it must be treated differently from ordinary indoor LED display. Outdoor LED display installation requirements are not the same as ordinary indoor LED. In the installation must be done in detail. It is very likely to cause trouble.
