Full-color LED display fault has many are caused by improper installation, so the installation need in strict accordance with the steps to operate full-color LED display, especially the installation for the first time, so that we can reduce the error occurred, take a look at below steps full-color LED display installation, wiring method.
1. Check the power supply voltage
Find 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 post) and plug in the power. Will find the power supply has a lit up, and then use a multimeter, dc gear measuring the voltage between V + and V -, to ensure that the voltage from 4.8 V to 5.1 V, there was a knob, can cross screwdriver to adjust the voltage. In order to reduce the screen febrile extension of life, the voltage can be adjusted to between 4.5v-4.8 in the case of low brightness requirement. After the confirmation voltage is not a problem, disconnect the power and continue to assemble the other parts.
2. Connection power
Turn the power off first, connect the V + to the red line, V - connect the black line, connect to the control card and LED cell, black wire connect control card and power supply GND. The red line connects the control card with the + 5V and the VCC of the cell board. Each unit plate has one power cord. Once completed, check if the connection is correct.
3. Connection control and unit plate
Make a good line, connect. Pay attention to the direction, not the reverse. Please note that the interface of the unit board 2 16PIN, 1 is input (in), 1 is output (out), and close to 74hc245/244 is input, and the control card is connected to the input. The output is connected to the input to the next cell.
4. Connect the RJ45 line (data line)
Connect A computer to A computer network card port or send A network port, the other end of the control card, connect the rest of the control card in A - B, a-b.
In order to achieve optimal compatibility, T568B standard is usually adopted for making straight lines. RJ45 crystal needle head serial number should be in accordance with the following methods: observing the RJ45 plug (with one side of the copper needle) positive towards yourself, have a copper needle head upper part, one end of the connecting cable in lower part, from left to right to eight copper needle Ordinal Numbers for 1 ~ 8:
White - orange, orange, white - green, blue, white - blue, green, white - brown, brown
5. Check attachment
Check again if the connection is correct, and the black wire is connected to -v and GND. The red line is connected by + V and VCC + 5V.
Connect the red line to the L, the blue line to the N, and the yellow and green line to earth
6. Test
Connect to 220V and open the downloaded software. Normally, the power lamp is bright, the control card is shiny, the screen is displayed. If not, check the attachment. Or check for error checking. Set the screen parameters and send subtitles. Specific reference software usage instructions.
