What is data group swap and split, and how can they make the LED screen display correctly and systems run efficiently?
When configuring an LED display, you might think that ensuring accurate visual output is a complex challenge, especially with intricate setups.
However, with the right configuration techniques, you can streamline this process and significantly enhance display accuracy and efficiency. Two vital techniques in this context are data group swap and split.
In this article, we’ll explain what data group swap and split are and how you can use them to optimize your LED displays, ensuring they perform at their best.

What is a Data Group?
A data group refers to the set of signals that control the red, green, and blue (RGB) LEDs on an LED screen module. These signals originate from a receiving card and are delivered to the module through flat cables or a signal adapter board.
To illustrate, consider a module with a HUB75 interface, which allows for two sets of data input.
According to the LED module’s interface specification, each set of RGB signals is identified as one data group. You can see there are two sets of RGB as follows.
Why do we need to swap the data groups?
Data groups output from the receiving card are typically arranged in a specific sequence by default. For instance, with a 5A-75B receiving card, the data groups are usually output sequentially from interfaces J1 through J8.
However, the actual physical arrangement of modules during installation might not align with this default sequence. If the physical installation order differs from the default data group order, the screen will display images incorrectly or chaotically.
Here the image is chaotic.
Therefore, it’s necessary to adjust the data group output order to match the modules’ physical arrangement to ensure correct image display on the LED screen.
What is Data Group Split Style?
There are limitations on the length and capacity of a data group. To avoid issues with display quality and limitations due to overly long data groups, we may use multiple data groups for controlling more pixels in the transmission direction.
Following is an image of the limitations of the Data group.
Following is an image of multiple data groups to control the pixels.
No Split: a single column of data groups manages pixels along the data cascade, is referred to as “No Split.”
For example, following shows the module installation way.
In this way, the data for 16 modules is provided by 4 interfaces of the receiving card. Each set of 4 modules is cascaded together and jointly controlled by 2 set of data groups from one interface. The approach of using only one column of the data group to control the pixels in the data cascade direction is referred to as “No Split.”
2 Splits: With two columns managing the pixel data.
We still use the 16pcs module as an example. Alternatively, the 16 modules can be controlled by eight interfaces. Each set of two modules is managed together by two data groups from one interface, divided across two columns.
As you can see from above image, the receiver card adapts 8 interfaces to connect the 16pcs module. These modules are divided into 2 columns. The approach of using 2 columns of data groups to control the pixels in the data cascade direction is referred to as “2 Splits”. If both columns cascade data in the same direction, it is termed “Same Direction 2 Splits”
4 Splits: With four columns managing the pixel data.
In another configuration, 16 modules are also controlled by 16 different interfaces, with each module independently managed without cascading. These modules are divided into four columns. The approach of using 4 columns of data groups to control the pixels in the data cascade direction is referred to as “4 Splits”
Other split styles follow this principle, with Colorlight’s standard firmware supporting up to eight splits. It’s crucial that each data group does not control more than 8,192 pixels.
Download and Run LEDSettting
Once you understand what data group swap and split entail, the next step is learning how to configure these settings correctly to maximize your LED display system’s performance.
To effectively swap and configure data groups and split styles, the first step is to download LEDVision, which includes a software tool called LEDsetting. This software offers an intuitive process for managing your LED display settings, making the configuration straightforward and user-friendly. Next, run the EXE program to install on your local computer.
After installation, you’ll notice two icons: LEDSetting, for configuring parameters, and LEDVision, for video playback. To proceed, simply open LEDSetting by either double-clicking the icon or right-clicking and selecting “Run as administrator.”
Set Split Style
To swap and configure data groups and split styles, enter the “Screen Configuration” mode with the password (168 or 777).
Click on “Receiver Parameters” to enter the settings interface. Verify the module information; if incorrect, use the intelligent settings to confirm the information is right.
Before swapping data groups, configure the split style based on the connection between the receiving card and modules. For example, as follows, the configuration is “2 Split (Same Direction),” so we select the corresponding option.
Select the split style as follows.
Set Data Group Swap
After that, you may notice the LED display showing a chaotic image. To restore it to normal, you’ll need to swap the data groups. Click on “Data Group Swap” to begin the process.
After that, you may notice the LED display showing a chaotic image. To restore it to normal, you’ll need to swap the data groups. Click on “Data Group Swap” to begin the process.
select “Intelligent Mode” and “Re-route groups” After that, the modules will display a white square indicating the position of each data group. Then, click on each corresponding position in LEDsetting one by one. Finally, click “Close” to finish the data group swapping operation.
Note that unused receiving card interfaces won’t transmit data, which means no white square will appear during swapping. Click “Empty Group” to bypass these until a white square is visible.
Last, confirm that the LED screen displays correctly. You can click the “Test Tool” to test. If so, select “Save to Receiver” to secure parameters and prevent loss if the screen loses power.
Conclusion
By implementing data group swap and split techniques, you can transform disorganized displays into vividly accurate visual presentations. This not only optimizes the functionality of your LED screen but also elevates the overall viewing experience.
