How to connect the external control line of the lighting digital tube is simpler?

It should be that the signal controller cannot be connected with the new digital tube signal, unless you will replace the crystal oscillator yourself! Otherwise, the only way to do this is to replace the similar or identical digital tube.

The IC model inside is not the same, whether the signal is correct at the corner of the wire, and the data. Locking. None of the clocks and other signals can be misconnected.

There is generally no problem with a new digital tube, as long as it can be bright, it generally means that it is good. You can test the digital tube. I don't know what your control circuit looks like, it's generally triode controlled, you disconnect the pins of the control chip and test whether the triode can light up the digital tube correctly.

Of course, before doing these things, it is best to test whether the power supply voltage is normal, including whether the voltage of the main control chip is normal.

Upstairs, didn't you consider the "model" mismatch? You test whether the pin pin is the corresponding first.

If you change the crystal oscillator, or if there is a problem with the capacitor, it is the crystal oscillator part.

It is a mismatch between the digital tube and the controller.

It depends on what you want. It depends on the grade you want, the simple installation and construction of the internal control is convenient and cheap. The external control is a little more high-end than the internal control.

In addition, there are line lights, as well as DMX512 line lights. There are all kinds of them. The cheap ones are more than a dozen yuan a meter, and the expensive ones are hundreds of dollars a meter.

Choose according to the needs of the project.

I want to know how many meters of pipe you use.

This makes it a good match for the controller.

I can help you make a wiring diagram.

By the way, it doesn't have to be 104 (, generally 103-105 is fine, and usually bigger is better.) Eliminates high-frequency radio waves. Protect the LEDs.

It's bucked, and you can't take it that much.

Use a 220 power cord to disconnect every six and connect to the mains power supply.

First, there is no signal transmission, check the controller or the line.

You asked, I didn't give any information, what lights, colorful or full color point by point? What model of controller is dressed up in? How many lines is line infiltration? There is no information in the hall to shout that you are looking for answers?? The best thing to do is to call your **ask your **quotient directly.

There are synchronous and asynchronous ones, and there are connection diagrams

Connect to a relatively stable high level, such as +5V (relative error <5%), or connect to the high and low level interface and point the switch to the high level.

Connecting 1 is to connect the high level, and the terminal that needs to be connected to 1 is always given high level through the control.

Give high to the terminal that needs to be connected to 1.

Look for relevant documents and other materials for this. Or take a look at the technical documentation. Or go to the Big Bit forum and post to ask.
