LED display control card seven common sense
With the rapid development of the LED industry, the demand for the LED display control card market is also increasing, and the wireless LED control card can well meet the customer's unified management, the needs of the cluster to send the market. For example, community promotion LED screens, on-board screens, government projects, mobile phones, telecommunications, bank door screens, batch installation, easy management, and maintenance-free status are the best choices for users. Then when using the control card, in order to avoid unnecessary losses, the following points should be noted:
Keeping the control card in a dry, relatively stable environment, excessive temperature, humidity, and dusty environment is extremely detrimental to the control card.
It is forbidden to insert and remove the serial port without power off, so as not to damage the computer serial port and the control card serial port due to improper operation.
It is strictly prohibited to adjust the input voltage of the control card when the system is powered. This may damage the serial port of the computer and the serial port of the control card due to improper adjustment and high voltage. The normal operating voltage of the control card is 5V. When adjusting the power supply voltage, the control card should be removed and the slow adjustment measured with a multimeter.
It is forbidden to connect the grounding terminal of the control card and the frame of the display short circuit. Otherwise, once static electricity accumulates on the display frame, the serial port of the computer and the serial port of the control card can be easily damaged, resulting in unstable communication, and the control card and the screen body will be burnt when the static electricity is severe. Display unit. Therefore, when the outdoor screen or communication distance is long, it is recommended that the user must use a serial port isolator in order to avoid damage to the computer serial port and control card serial port due to harsh environment such as ground loop, surge, induced lightning, and hot swap.
The correct connection between the control card and the serial port of the computer must be ensured so as not to damage the serial port of the control card and the serial port of the computer due to incorrect input signals.
Do not connect the control card to the cell board. To directly lead to the switching power supply, the voltage of the cell board during operation is unstable. It will cause the control card to be fast and slow, serious communication can not be carried out or the program needs to go back to repair, especially U disk control card, in the case of unstable voltage may not be able to read the disk or read the disk error.
Many indoor single-color or two-color, or even full-color, and then directly connected to the control card without debugging power, there may be a large area burned behind the unit board scan drive chip. Please debug only one unit board after commissioning, unplug the power after commissioning, and then connect the control card.
The LED display control card is the core device of the product. It is very necessary to master the above common knowledge of the control card.
