When using an outdoor LED display , it often fails to load. LED display manufacturer Yingbao Electronics analyzes the reasons why the LED display cannot be loaded from the following aspects.
1. Check if the jumper cap is loose or fall off; if the jumper cap is not loose, please make sure that the jumper cap is in the correct direction.
2. Check that the serial cable used to connect to the controller is a straight-through cable, not a crossover cable.
3. Check and confirm that the serial port cable is intact and there are no loose or falling off at both ends.
4. Compare the LED display control software and the control card of your choice to select the correct product model, the correct transmission mode, the correct serial port number, the correct serial transmission rate, and correctly set according to the DIP switch diagram provided in the software. Controls the address bit and serial transfer rate on the system hardware.
5. Ensure that the control system hardware is properly powered.
6. If the above check and correction still does not load, please use a multimeter to measure whether the serial port of the connected computer or control system hardware is damaged. To confirm whether it should be returned to the computer manufacturer or return the control system hardware for testing.
In short, the reason why the LED display is not loaded properly may be caused by the product itself, or it may be caused by improper operation during use. As long as you think carefully or ask the manufacturer, it is easy to find the root of the problem.
