What is the default password for the parameter setting of the led display screen?

In the previous chapter, we talked about the commonly used software of LED display. In this chapter, we will talk about the default password for various LED display screen parameter settings.

Many customers, after downloading the control software of the LED display, follow the tutorial step by step, and often get stuck in the screen setting of the LED display, because some tutorials do not give a password directly, which leads to many customers. I don’t know how to proceed.

Some customers did not know the password because they used a new LED control card software, which caused the screen parameters of the display screen to be unable to be set. This is really a headache. Here is a list of the user names and passwords of several common led display control card software.

Nova Technology:

Username: None Advanced user password: 666; maintenance user: 444; debugging user: 555; some software (such as NovaLCT-Mars) user password is admin

Carlette:

Username: None Password: 168

Sporadic rain:

Username: linsn Password: 168

Zhongqing:

Username: zdec Password: 168

Depoda:

Username: dbstar Password: 168

Some more brands are either 168 or 888, 666, 666666, 88888, 888888

From the above passwords, we can infer that the default passwords of general systems are relatively easy to guess. If the above passwords are not correct, we can also try to guess other passwords, such as 123, 123456, 12345678, etc., and they are correct. After the password is set, let’s take a look at how to set the remaining display screens. Here we take the signboard on the entrance of the store as an example to set the screen parameters.

First, screen parameter setting

Customers who use the LED control card for the first time need to use the corresponding LED display software to set up through the RS232 cross-serial cable; for the notebook, please use the USB to 232 cable.

After the software runs, it will automatically “find the display screen”. If the automatic search fails for multiple times, please check whether the serial port cable is a “cross cable”, whether it is plugged in properly, and whether the control card is working properly. Note: It is strictly forbidden to plug in the serial cable when the power is on. Please turn off the power before plugging in the cable.

The control card password is “168”, and the screen will display “No information currently” after the screen parameters are set correctly.

E.g:

If it is an outdoor P16 screen, the interface is 12 interfaces:

The parameters are: Data polarity: low OE polarity: high Scan mode: 1/4 scan, the default is 4.3 scan mode

Second, program editing and management

After setting the screen parameters on the display screen, you can directly click the icon in the toolbar to add a program. E.g:

1) Subtitled programs

In the hypertext RTF file program, the RTF hypertext can set the font, size, and different colors for each character, and can maintain the hypertext file of the program separately for later recovery. You can enter all languages ​​supported by the Windows system (such as Korean, Arabic, etc.), and each text in the hypertext can be individually set in color, size, and font. Select the font with “@” in the font column to set the font display of the couplet screen.

2) Time-based programs, digital real-time clock (multiple common modes are optional).

3) Countdown program, the maximum time is 9999 days.

4) Picture-based programs, supporting various picture formats such as bmp and jpeg.

5) Form program, supports electronic form.

6) Animated programs, support gif and other formats.

7) Temperature and humidity program, support temperature and humidity function.

6) Text program, supports input of simplified, traditional, English and other fonts.

Third, send the program in the LED display control software.

When all the added programs are edited, click “Send All”, and the program can be displayed on the screen after the transmission is successful.

If you encounter faults such as incomplete or non-display of the LED display, you can first try to detect which part is the problem. If the problem is not resolved, it is best to contact the manufacturer’s technical staff to help solve it, and restore the display to normal work as soon as possible.
