What Is Nova LCT?

NovaStar NovaLCT is a software used on Windows to configure the control system, monitor, set, and adjust the LED Screen. It can be used as:

  • NovaLCT LED Configuration Tool for Synchronous Control System: The images are played and controlled on the screen synchronously with the video source (such as on a PC or camera).
  • NovaLCT LED Configuration Tool for multimedia players of Asynchronous Control System: The resources are played and controlled asynchronously. The program is pre-stored on the local device. Then, it will be sent and played on the LED screen wall.

2. NovaStar NovaLCT V5.4.8

3. NovaLCT Install

Ensure you have a Windows PC ready before setting up NovaLCT. Temporarily turn off any antivirus software to prevent installation interference.

Extract the contents of the installation package, initiate the .exe file, and proceed with the instructions provided by the setup wizard to finalize the installation process.

Should a firewall notification emerge, permit the installation to continue. In instances where your PC lacks the serial port driver or possesses an outdated version, the NovaLCT installer will take care of the installation or update automatically.

NovaStar Nova LCT Applications

NovaLCT displays different features and parameters when working with different devices and programs. It can be used in NovaStar sender boxes, Nova MCTRL 600 controllers, Nova MCTRL 660 controllers, NovaStar VX4S controllers, etc.

1. NovaLCT LED Configuration Tool for Synchronous Control System

In synchronous mode, the PC is only used to control the LED display wall, and the media source is transferred by DP/HDMI/DVI cable from other devices.

If the hardware is successfully connected and the sending card is operating normally, NovaLCT will connect to the sending card automatically. After the successful connection, the NovaLCT main window displays the sending card quantity and monitoring information about the control system.

2. NovaLCT LED Configuration Tool for Asynchronous Multimedia Play Control System

In this asynchronous mode, the ethernet works as the control cable and media source transmission cable (the media sources are stored on the PC).

Direction connection via Ethernet cable:
Simply connect the control computer to the Multimedia Player using an Ethernet cable. For this to work, ensure the Multimedia Player’s DHCP is active. Then, in NovaLCT, navigate to Plug-in > DHCP Service, choose your PC’s IP address, and activate the DHCP Service.

Direction connection via Wi-Fi:
Link the control computer, which runs NovaLCT, to the Multimedia Player over Wi-Fi. If your Multimedia Player comes with an integrated Wi-Fi AP, this connection can be established without any additional setup.

Divice Direct Connection via Ethernet Cable and Wi-Fi

Wired LAN connection:
Connect your control computer and multimedia player to the same wired LAN using an Ethernet cable. This plug-and-play method requires no additional configuration.

Wireless LAN connection:
For a wireless setup, ensure both the control computer and multimedia player are on the same Wi-Fi network. This connection type is viable if your multimedia player is Wi-Fi STA compatible. Remember to enable the player’s DHCP settings. To connect, use configuration software like ViPlex to log into the multimedia player, then link it to the router’s Wi-Fi AP via the network configuration page.

NovaLCT Manual & User Guides

The operation guides are available with asynchronous and synchronous modes.

1. How to Update NovaLCT Software?

If you’re not running the latest Nova LCT software, an “Online Update” dialog will appear. To update to the new NovaLCT version, follow these steps:
Step 2: Click OK.
Step 3: Click Get Update.
Step 4: Once you have downloaded the update packag, click Install Update and wait for the installation.

2. NovaStar LCT Screen Configuration

To quickly complete screen configuration, load either a cloud or local configuration file. It’s important to note that NovaLCT is currently limited to configuring standard screens only.

  • For a Cloud Configuration File: Ensure the control computer has an internet connection.
  • For a Local Configuration File: Have the system configuration file (.scfg and .zip) ready.

While you can view the information in both the cloud configuration file and local .zip file within NovaLCT, editing is not possible until the data is transmitted to the hardware.

Conversely, the local .scfg file allows for both viewing and editing in NovaLCT before sending the information to the hardware.

Operation Steps:
Step 1: Access the multimedia player by logging in.
Step 2: Navigate to Settings > Screen Configuration via the menu bar to initiate the dialog.
Step 3: Choose one of the following methods to upload a configuration file as needed.

Load from the cloud platform

  • Choose “Cloud Restore” and pick a node from the dropdown menu.
  • Hit “Next” to bring up the “Restore Configuration File” dialog.
  • Select the appropriate tab and dispatch the configuration file to your hardware.

Receiving Card: Opt for “Send By Topology” or “Send By Physical Address,” adjust the necessary parameters, and click “Send to Specified RV Cards” to transfer the receiving card configuration file to your hardware. If selecting an area via the software is impractical when “Select by Topology” or “List” is chosen, use “Select Operating Area on Screen” to pick the area directly on the display window.

Screen Connection: Press “Send to HW” to forward the screen connection file to your hardware.
In the pop-up dialog, select either “Save to HW” or “Don’t Save to HW.”


Load from local PC

  • Select Local Restore.
  • Click Browse to select a configuration file, and Open it.

Refer to the visuals and steps under the “Load from cloud platform” section for the .zip local configuration file.

The loading progress for the .scfg local configuration file will be shown. Once the file is loaded, the dialog box will close on its own.

3. Firmware Program Update

Check and update your current firmware program version of the receiving card and sending card

Step 1: Sign in to the multimedia player.
Step 2: Enter “admin” to access the program loading interface.
