1. Overview
The NovaStar TB40 multimedia player is an asynchronous LED control device designed for LED display content playback, screen management, and cabinet-level control. It is commonly used in commercial LED displays, advertising screens, retail signs, public information displays, transportation screens, and small to medium fixed LED installations.
Unlike a traditional synchronous LED control system that depends on a continuously connected computer or video source, the TB40 can store content internally and play programs independently. After videos, images, text, or schedules are published to the player, the LED display can continue operating without a dedicated playback computer.
At the same time, the TB40 can also support external video input through its HDMI IN interface when a project requires occasional real-time display. This makes it useful for projects where scheduled playback is the main requirement, but HDMI input may be needed for presentations, temporary live content, or external media sources.
In a complete LED display system, the TB40 works together with:
Control computer
NovaLCT configuration software
LED receiving cards
LED cabinets
HUB boards or adapter boards
LED modules
Network cables
Optional HDMI input source
Optional cloud or network publishing system
Because the TB40 directly affects screen mapping, receiving card communication, playback control, and display stability, correct configuration is essential before project handover.
2. Before You Start: TB40 Configuration Checklist

Number of LED OUT ports used
Loading area of each Ethernet port
Physical network cable routing order
Starting cabinet position of each port
Whether the wiring is straight, S-shaped, or custom routed
Default IP address and WiFi information from the TB40 side label
It is strongly recommended to take a photo of the TB40 side label before installation. The label may include default IP address, WiFi name, password, device identification, and login information that may be needed during commissioning or maintenance.
3. Functional Positioning in an LED Display System
3.1 What Is the Role of the TB40?
The TB40 is positioned between the content source and the LED display hardware. It receives content, control commands, or video input, processes them through the LED control system, and outputs display data to receiving cards through LED OUT Ethernet ports.
A simplified signal chain is:
Computer / USB / Network / HDMI Source → NovaStar TB40 Multimedia Player → LED OUT Ports → Receiving Cards → LED Modules
In this system, the TB40 is not just a simple media player. It also acts as a control device that manages how the LED screen receives and displays image data.
Its core roles include:
Media content playback
LED screen configuration
Sending display data to receiving cards
Supporting screen connection mapping
Managing cabinet communication
Supporting asynchronous playback
Supporting HDMI input in applicable scenarios
Working with NovaLCT for setup and maintenance
3.2 Relationship Between TB40, Sending Card, and Receiving Card
In a traditional synchronous LED control system, a sending card receives video data from a computer, graphics card, or video processor. It then sends LED display data to receiving cards inside the LED cabinets.
The TB40 integrates media playback and sending functionality into one device. This reduces the need for a separate playback computer and sending card in many small and medium LED display projects.
However, the TB40 does not replace receiving cards. Receiving cards are still required inside LED cabinets to drive the LED modules.
The receiving card is responsible for:
Receiving display data from the TB40
Controlling the LED module scan mode
Driving LED pixels through driver ICs
Managing grayscale and refresh performance
Handling cabinet-level data distribution
Applying calibration and brightness information when supported
Therefore, TB40 configuration normally includes two important parts:
Receiving card parameter configurationThis defines how each receiving card drives the LED modules.
Screen connection mappingThis defines how each cabinet or receiving card is physically connected and arranged.
If either part is incorrect, the LED display may show wrong colors, incomplete images, reversed areas, disordered cabinet positions, or black sections.
4. Hardware Connection Before Configuration
Before using NovaLCT to log in and configure the TB40, complete the hardware connection first.
4.1 TB40 to LED Display Connection
Connect the LED display to the TB40 through the rear panel LED OUT Ethernet ports.
The general connection is:
TB40 LED OUT → Network Cable → First Receiving Card / LED Cabinet → Next Receiving Card / LED Cabinet
The TB40 supports multiple LED OUT network ports. The number of ports used depends on the LED screen resolution, cabinet layout, and controller loading capacity.
During installation, pay close attention to:
Which LED OUT port is connected first
Which cabinet is the starting cabinet
The physical order of the network cable connection
Whether the wiring follows an S-shaped path
Whether each port controls a separate screen area
Whether the actual wiring matches the planned screen map
Screen connection mapping in NovaLCT must follow the real physical wiring order, not only the visual screen layout.
4.2 TB40 to Control Computer Connection
The control computer can connect to the TB40 in two common ways:
Connection Method | TB40 Interface | Typical Use |
USB direct connection | Front USB Type-B | Recommended for stable initial configuration |
Ethernet connection | Rear ETHERNET | Used for LAN configuration and network management |
For first-time setup, USB direct connection is often preferred because it avoids many network-related issues such as IP segment mismatch, firewall blocking, or unstable LAN settings.
If using Ethernet connection, the computer IP address should be set to the same network segment as the TB40. The default IP address is usually shown on the side label of the device and may vary depending on batch, project settings, or supplier configuration.
4.3 TB40 to HDMI Source Connection
If synchronous input is required, connect the external video source to the rear panel HDMI IN interface.
Typical HDMI sources include:
Laptop computer
Desktop computer
Media player
Video processor output
Presentation device
Camera or switcher output, depending on system design
If the LED display is only used for asynchronous playback, HDMI IN does not need to be connected.
5. Working Principles of the NovaStar TB40
5.1 Asynchronous Playback Mode
In asynchronous playback mode, the TB40 stores content internally and plays it according to a program, playlist, or schedule.
The signal chain is:
Computer / Cloud Platform / USB / Network → TB40 Internal Storage → LED OUT → Receiving Cards → LED Modules
In this mode, content is first uploaded to the TB40. After publishing, the LED screen can operate independently without a continuously connected computer.
This mode is suitable for:
Advertising playback
Retail promotions
Public announcements
Storefront LED signs
Transportation information
Scheduled digital signage
Multi-location content management
5.2 HDMI Input Mode
In HDMI input mode, the TB40 receives real-time video from an external source.
The signal chain is:
Computer / Media Player / Video Source → HDMI IN → TB40 → LED OUT → Receiving Cards → LED Modules
This mode is useful when the display occasionally needs to show:
Computer desktop content
Presentation slides
External media player output
Meeting room content
Temporary event content
Real-time information from another device
Although the TB40 can support HDMI input in applicable scenarios, it is still mainly used as a multimedia player and asynchronous control device. For complex live video systems, a dedicated LED video processor or synchronous control system may still be required.
5.3 Configuration Logic
TB40 configuration through NovaLCT follows this logic:
Log in to the media player.
Configure receiving card parameters.
Send receiving card parameters to all receiving cards.
Configure screen connection mapping.
Send the screen connection map to hardware.
Confirm that the LED screen displays correctly.
Save or flash the configuration.
Restart the system and verify that the configuration remains valid.
This process ensures that both the receiving cards and the TB40 understand how the physical LED display is built.
6. Product Classification and System Architecture
6.1 TB40 as a Taurus Series Multimedia Player
The TB40 belongs to NovaStar’s Taurus series multimedia player category. This type of product is designed for LED display playback, publishing, and configuration control.
Taurus series players are widely used in commercial and signage-oriented LED display projects because they can combine media playback, screen control, and network management in one device.

8. How to Configure Receiving Card Parameters
8.1 Enter Screen Configuration
After logging in successfully:
Click Screen Configuration.
Click Next.
Enter the Receiving Card tab.
This page is used to configure how the receiving cards drive the LED modules.
8.2 Load the Receiving Card Configuration File
If the LED screen manufacturer provides a configuration file, use this method first.
Steps:
Click Load from File.
Select the correct .rcfgx file.
Open the file.
Confirm that the receiving card parameters are loaded correctly.
The .rcfgx file usually contains important technical parameters, such as:
Receiving card model
LED module scan mode

If no .rcfgx file is available, manual configuration may be required.
Important information includes:
Receiving card model
LED module pixel structure
Single cabinet resolution
Single receiving card loading width
Single receiving card loading height
Module scan mode
Driver IC type
HUB board interface type
Manual configuration should be performed by experienced technicians because wrong parameters may cause serious display abnormalities.
8.4 Send Parameters to Receiving Cards
After loading or setting the parameters:
Click Send to Receiving Card.
Select All Receiving Cards in the pop-up window.
Click Send.
Wait for the sending process to complete.
Check whether the LED screen response is normal.

9.1 Enter Screen Connection Page
After receiving card parameters are configured:
Switch to the Screen Connection tab.
Set the screen quantity.
For most single-screen projects, the screen quantity is usually set to 1.
Click Configure.
9.2 Set Port Loading Area
Each LED OUT port controls a defined area of the LED display. The loading area must match the actual cabinet resolution and wiring plan.
For example, one Ethernet port may load an area such as:
208 × 624 pixels
The exact value depends on:
Cabinet pixel size
Number of cabinets connected to the port
Receiving card loading capacity
Controller output capacity
Screen layout
Physical cable routing
9.3 Draw the Connection Route
After setting the loading area, draw the cabinet connection path according to the actual network cable sequence.
A common method is S-shaped wiring:
First row from left to right
Second row from right to left
Third row from left to right
Continue alternating direction row by row
However, the most important rule is:
The software connection map must match the real physical wiring order.
If the first network cable enters the top-left cabinet, the map should start from the top-left cabinet. If the first network cable enters another position, the map should start from that actual position.
9.4 Reset and Redraw If Needed
If there is already an incorrect connection map, click Reset All before drawing again.
Then:
Start from the first receiving card or first cabinet connected to the selected LED OUT port.
Click each cabinet one by one according to the real cable order.
Confirm the direction of each row.
Check the start position of each Ethernet port.
Make sure no cabinet is skipped or selected twice.
This step is one of the most common sources of display errors.
9.5 Send the Connection Map to Hardware
After the map is complete:
Click Send to HW.
Confirm in the pop-up window.
Observe the LED display.
Check whether the image is complete, correctly positioned, and normally spliced.

6. Why is my LED screen image scrambled after sending the connection map?
The most common reason is that the screen connection map does not match the actual network cable wiring order. Reset the map and redraw it according to the real cabinet connection route.
7. Why does the screen return to the wrong display after power restart?
This usually happens when the configuration was sent but not saved or flashed. After confirming normal display, save or flash the receiving card configuration and screen connection configuration.
8. Can TB40 work without a computer?
Yes. In asynchronous playback mode, after content is uploaded and configured, the TB40 can play content independently without a continuously connected computer.
9. Can TB40 display HDMI input?
Yes, the TB40 can use HDMI IN for external video source input in applicable scenarios. This is useful when the LED screen occasionally needs to display content from a laptop, media player, or other HDMI source.
10. Is TB40 suitable for large LED video walls?
It depends on the screen resolution and loading capacity. For large LED video walls, high-resolution fine-pitch displays, or complex video systems, a higher-capacity controller or professional LED video processor may be required.
