Use LED Display Control Card Caution
Apr 27, 2016

1, the control card, do not connect the cell board. To try to lead directly to the switching power supply, cell plate voltage and instability in the course of their work. When the control card will cause faster or slower, can not communicate or serious need to rework the program running, especially U disk controller card, at a voltage instability or could not read the disk read errors.

2, the indoor, 16 sweep unit board should not take the whole screen debugging, a lot of indoor monochrome or color, or full color, and then debug state not directly connected to the control card power, there may be a large area of burn unit to sweep behind the plate line driver chip 4953 . Debugging only take one unit board debugging, debugging unplug the power, connect the control card

 3, the control card Keep in a dry, relatively stable environment, high temperature, and humidity, as well as a dusty environment, the control card is extremely unfavorable.

4, in the absence of power, non-plug port to avoid damage due to improper operation of the computer serial port and serial port control card.

5, when the system is energized to work non-adjustment control card input voltage, due to the adjustment in order to avoid improper voltage is too high and damage the computer serial port and serial port control card. Control card normal working voltage of 5V. Adjust the power supply voltage, you should remove the control card, use a multimeter to measure the slow adjustment.

6, is strictly prohibited ground control card and the display frame shorted, otherwise the display frame once gather static electricity, easy to damage the computer serial port and serial control card, communication is not stable, it will burn out the control card and the electrostatic screen serious on the display unit. Therefore, when the communication distance or outdoor screen, the user must use the serial port isolators to avoid ground loops, surges, lightning sensors, hot-swap and other harsh environmental damage to the computer serial port and serial port control card.
