Parameters and configuration methods of LED display control software

When setting the software parameters of the LED display control card, we often encounter some problems. For example, I don’t know how to set the parameters, what the password is, I can’t find the software, and so on. The manufacturers of LED display control cards are different, and the number of parameter items is also different. Here we have classified them, which can be roughly divided into three types: basic parameters, auxiliary parameters and core parameters:

Three parameters of LED outdoor display control software:

First, the basic parameters

The basic parameters are the basic parameters of the outdoor LED screen. If the settings are not correct, it will not be able to communicate or not display and the display will be abnormal. The basic parameters include display screen width and height, control card address, baud rate, IP address, port number, MAC address, subnet mask, gateway, refresh frequency and shift clock frequency, a total of 10 items.

Second, auxiliary parameters

Auxiliary parameters are parameters set for better display and control, including four items including control card name, communication display mark, brightness, and switch screen time.

Third, core parameters

The core parameters are the necessary parameters for the LED outdoor display. If the settings are not correct, the display will not be displayed, and the screen will be burnt in severe cases. The core parameters include cascading direction, OE polarity, data polarity, display type, color, scanning mode, moving point sequence and line sequence, a total of 8 items.


LED display control software parameter configuration method:

For the configuration of basic parameters and auxiliary parameters, an input box and a selection box are provided. After the user inputs and selects, it can be directly set by connecting the display screen. As for the core parameters, they can be completed by using three methods: professional quick check, smart configuration and external file configuration.

Professional Quick Check

For common and commonly used types of display screens, the parameters are generally fixed. At this time, they can be organized into files or tables in advance, and you can choose to load the configuration when debugging.

Intelligent configuration

For uncommon or undetermined display screens, whose parameters are unknown, intelligent configuration can be used at this time to determine their configuration parameters, and then save them for future use.

External file configuration

Import external files built by smart configuration or other means into configuration.

Among the three configuration methods of core parameters, intelligent configuration is the more important configuration method, and its main processes and functions are as follows:

  • Start Smart Configuration.
  • Through the wizard, let the user and the display screen perform human-computer interaction selection, start the intelligent configuration operation, fill in the initial parameters, determine the OE polarity/data polarity, determine the color, determine the scanning mode, determine the sequence of moving points, and determine the row Program and generate configuration parameters and other steps to complete the determination of core parameters.
  • Return the intelligent configuration parameters.
  • Connect the display and set the parameters.
  • If it is correct, perform the output parameter operation.
  • Select the external file and save it for future downloads. At this point, the intelligent configuration of the display screen is completed.

Summary: The outdoor LED display needs to be correctly configured with more than 20 parameters to light up, which is cumbersome and complicated. If the settings are not correct, the display will not be displayed, and the display screen will be burned, causing major economic losses and delays in the construction period. Therefore, it is understandable that some LED display control software is complicated in design and inconvenient to use for the sake of prudence and safety.
