As the LED display manufacturers in the production of LED display are different, and that its basic parameters will be different, but according to different categories, we can roughly divide them into three categories, here we come to study the following several parameters together .
First, basic parameters
The basic parameters are the basic parameters of the display. If the settings are not correct, they cannot communicate or display and the display is not normal. The basic parameters include the width of a display screen height, the control card address, baud rate, IP addresses, port numbers, MAC address, subnet mask, gateway, and a shift clock frequency of the refresh frequency of 10 items.
Second, auxiliary parameters
Auxiliary parameters are parameters set for better display and control, including control card name, communication display mark, brightness, and switch screen time .
Third, the core parameters
The core parameters are the parameters necessary for the display. If the settings are not correct, the light is not displayed, and the screen is burned. Core parameters including cascaded direction, OE polarity, the polarity data, display type, color, scanning, line-sequential order, and take the point total eight.
For the configuration of basic parameters and auxiliary parameters, input boxes and selection boxes are provided. After user input and selection, the display screen can be directly set. For the core parameters, it can be completed by three methods: professional quick check, intelligent configuration and external file configuration.
1 , professional quick check
For common and common models of outdoor displays, the parameters are generally fixed. In this case, you can sort them into files or tables in advance, and you can choose to load the configuration during debugging.
2 , intelligent configuration
For displays that are uncommon or undetermined, the parameters are unknown, and intelligent configuration can be used to determine their configuration parameters and then save them for later use.
3 , external file configuration
Import an external file that is intelligently configured or otherwise built into the configuration.
Among the three configuration methods of core parameters, intelligent configuration is an important configuration method. The main processes and functions are as follows:
1. Start smart configuration.
2. Through the wizard type, let the user and the energy-saving LED display 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 walking order, Determine the line sequence and generate configuration parameters to complete the determination of the core parameters.
3. Return the smart configuration parameters.
4. Connect the display and set the parameters.
5. If correct, perform the output parameter operation.
6. Select an external file and save it for later download. At this point, complete the intelligent configuration of the display.
In summary, a display screen needs to be correctly configured with more than 20 parameters to illuminate, and its cumbersome and complicated degree can be imagined. Since the manufacturing cost of the LED display screen is relatively high, if the setting is not correct, the light is not displayed, and the display is burned, causing major economic loss and delay in construction period. Therefore, some LED control software is prudent and stable, and the design is complicated and inconvenient to use.
