2. Novastar mctrl300 Operating Principle

Nova mctrl300 is an independent control card of the Nova M3 Led Display Control System series, which can support audio and video input. The working principle is to send audio and video to the led display mainly through internal encoding and data processing. The USB port communicates with the PC and automatically adjusts the screen brightness.

This also shows that the mctrl300 led display controller can quickly find and solve the problems that occur during the use of the led display.

Mctrl300 led display controller taking NovaLCT-Mars software as an operating platform, used in conjunction with data transceiver card, monitoring card and multi-function card, users can easily control all key information of the led display on the PC side and perfectly display the playback content.

Mctrl300 software setting and LED display connection channel:NovaLCT—MARS

The NovaLCT used by Novastar mctrl300 is the software for controlling and managing the Nova M3 series control system. The software integrates LED display configuration, timing automatic adjustment, LED display cabinet status, and LED display light point detection function.

Nova Electronic Technology has three kinds of control system software: the first one is NovaLCT-MARS mentioned above, and there are two other kinds, namely: COB calibration system, point-by-point calibration system.

Based on Nova’s powerful cloud platform, and with the cooperation of advanced software, you can remotely manage and control the screen anytime, anywhere.

Connecting to the display via NovaLCT-MARS:

1. Start the LED display, use the system configuration file to start the LED display, the procedure is simple, and no manual configuration is required.

The following is the operation diagram:


Startup step 1: Set the communication port of the current operation

Startup Step 2: Load the System Configuration File

2. Manually start the LED display, this step is more complicated (link document)

Adjust the Performance Parameters

Adjust LED Display Resolution and Refresh Rate

Set Hot Backup for Receiver Cards

Save Settings to FLASH

Save/Load Configuration Files

3. Adjust the brightness, display quality, Gamma and Current Gain

Cob LED calibration system operation principle:


Auto Adjustment

Mctrl300 Auto Adjust can adjust the display brightness according to the external environment, using a light sensor to determine the brightness of the environment.

The following are the steps to set the automatic brightness interval.

Sep1. Right-click on the circled panel and select Advanced Settings

The Advance Setting window for auto brightness

The Advanced Setting window for auto-brightness

Step 2: Set the detection period and reading time value of the light sensor

Through the hardware connection, when NovaLCT and hardware can not be linked, it can be configured as automatic, and the operation method is basically the same as automatic adjustment.

Display control

Click the Display Control button from the toolbar or select Tools->Display Control from the main

menu of the NovaLCT-Mars application main interface to open the Screen Control window

Check hardware info

Click Tool ->Hardware Information from the main menu to open the Hardware Information page. Shown in Fig.5-58 is the Hardware Information page.

Manage the led display

To make brightness control and monitoring easier, multiple LED displays can be combined

together. The combination is called a combination display.

Select Tool ->Multiple Screen Management to open the Combination Display Config window for combination display configuration. Shown in Fig.5-59 is the Combination Display Config window.

Mctrl300 price Estimate

Mctrl300 is a cost-effective controller, mainly used in rental and fixed installation displays, such as event sites, security control centres, stadiums, etc.

The development of any electronic product requires human and material resources for support, so the price is also based on these factors.

According to the price of various platforms, the market price of an mctrl300 led display controller box is about 200-300 U.S. dollars, and the shipping cost varies from country to country.

Now, mctrl300 updated some features, able to cascade 20 devices at the same time, so if you buy the LED display does not exceed this number, then you buy a controller on it, if you buy the LED display more than this number, may need to spend higher costs on the led display controller, want to better present the led display playback content will need a stable and reliable controller, once the problem can also be solved in time, and this is also able to recycle, so the cost is not too high.
