Full color LED display of the failure of many are due to improper installation, so in the installation of Full-color LED display needs to strictly follow the steps to operate, especially the first installation, this can reduce the error occurred, the following together to see Full-color LED Display installation wiring method steps.
1. Check the power supply voltage
Locate the DC positive and negative connection switch power supply, connect the 220V power cord to the switching power supply, (confirm the connection is correct, connect to AC or NL terminal) and plug in the electricity. Will find the power supply has a light, and then use a multimeter, DC gear to measure the voltage between + and V, to ensure that the voltage between 4.8v 5.1V, there is a knob next to the Phillips screwdriver to adjust the voltage. In order to reduce the screen fever prolong life, in the case of low brightness requirements, the voltage can be adjusted to 4.5v-4.8. After confirming the voltage no problem, disconnect the power and continue assembling the other parts.
2. Connect the Power
Turn off the power supply, connect the + to the Red line, v connect the black wire, connect to the control card and the LED unit board respectively, the black thread connects the control card and the power supply GND. The red Line connects the V of the control card and the VCC of the unit plate. 1 Power cords per unit board. When you are finished, check to see if the connection is correct.
3. Connection Control and Unit board
Use a good line to connect. Pay attention to the direction, can't answer. Note that the Unit 2 16PIN interface, one is input (in), one is output (out), near 74 C24 is input, the control card is connected to the input. The output is connected to the input of the next cell board.
4. Connect RJ45 network cable (data cable)
Will do a good network cable to connect the computer network card port or send card network, the other end of the connection control card, the remaining control cards in-,-form one by one.
5. Check the connection
Check to see if the connection is correct, and the black line is connected to-V and GND. The red line is connected to the + and VCC v.
Red Line connect L, blue wire to N, yellow-Green Line grounding
6. Testing
Connect to 220V and open the downloaded software. Under normal circumstances, the power supply light, the control card shiny, screen display. If this is not normal, please check the connection. or check for error checking. Set the screen parameters and send subtitles. Specific reference software usage instructions.
