How To Use LED Display Control Card Correctly?

With rapid development of the LED display industry, the demand for the LED display control card market is also increasing, and the wireless LED control card can well meet the needs of customers in the unified management and cluster transmission market. For example, poster led screen, taxi top LED display, light pole LED display and led player. Convenient management and easy maintenance led display control card are good choices for users. In order to avoid unnecessary losses, users should pay attention to the following points when using the control card.

First, put the control card in a dry and stable environment. Excessive temperature and humidity and dusty environment are extremely harmful to the control card.

Second, it is strictly forbidden to plug and unplug the serial port without power failure to prevent improper operation from damaging the serial port of the computer and the serial port of the control card.

Third, it is strictly forbidden to adjust the input voltage of the control card when the system is working, so as to avoid damage to the computer serial port and the control card serial port due to improper adjustment and excessive voltage. The normal working voltage of the control card is 5V. When adjusting the power supply voltage, the control card should be removed and adjusted slowly with a universal meter.

Forth, it is strictly forbidden to short-circuit the ground terminal of the control card with led display frame, otherwise, if static electricity accumulates , it is easy to damage the serial port of the computer and the serial port of the control card, resulting in unstable communication. If the static electricity is severe, the control card and led screen will be burned. Therefore, when led screen control distance is far, we recommend users must use a serial port isolator to avoid damage to the computer serial port and control card string due to harsh environments such as ground loops, surges, induced lightning strikes and hot plugging line port.

Fifth, it is necessary to ensure the correct connection between control card and computer serial port to avoid damage to the control card serial port and the computer serial port due to incorrect input signals.
