With the rapid development of LED display screens, electronic display screens are ubiquitous no matter in outdoor squares. Meeting shows, monitors or schools. Stations and shopping, transportation and other occasions.
However, with the popularization and application of display screens, LED display screens often cannot be loaded during use. This will also cause a black screen to appear when we use the display in the future. What causes the LED display to fail to load? 1. Check and confirm that the serial cable connected to the controller is a straight line, not a crossed line.
2. Make sure that the control system hardware is powered on correctly. If there is no power on, it needs to be powered on as soon as possible. 3. Check and confirm that the serial connection line produced by the LED display is intact, and there is no looseness or falling off at both ends. 4. Check if the jumper cap on the screen is loose or falls off, if not, please make sure the direction of the jumper cap is correct.
5. According to the control software and control card of the electronic screen, select the correct product model, correct transmission mode and serial port number, and correct serial transmission speed, and set the position of the control system hardware according to the switch diagram provided in the software. If the above checks have not been loaded, it is recommended to use a multimeter to measure. After determining whether the hard serial port of the computer or control system connected to the LLED display is damaged, in order to solve the loading problem, whether the LED display supplier should restore it and then repair it.
