NCP File Instruction Manual
2 NCP File Introduction
2.1 About NCP File
Background
In the past, to ensure the normal function of the screen, it was common practice to use a cabinet configuration file (.rcfgx) to light up the display, use an image quality file (.nrf/.vglcx) to improve the display effect, and use firmware program (.zip) to update the screen functionalities. Moreover, all these files need to be coordinated so they comply with each other. This can be somewhat cumbersome for the on-site staff as how to obtain these files and how to properly store them would not be an easy task. However, now with the brand new COEX control system, users can complete the entire cabinet debugging process with a single NCP file.
Introduction
Six in one, the NCP file combines the cabinet configuration file, receiving card firmware program, image booster (cabinet optical correction), frame rate adaptive parameters, mode adjustment parameters, and thermal compensation (cabinet thermal correction) into one file. By uploading the NCP file from a computer or pre-loading the file in the control system, users can utilize the NCP file at any time to light up the screen with a few clicks and achieve optimal display effects. To generate the NCP file from the Cabinet Tool, please contact NovaStar technical engineers before the screen leaves the factory.
Figure 2-1 NCP file content

2.2 NCP Features
Compared to the old-fashioned cabinet configuration file (.rcfgx), the cabinet library file (.ncp) enables users to light up the screen with just a few clicks. On top of that, the display effect configurations stored in the file are made by NovaStar technical engineers to ensure better display effects.

2.4 NCP File and Driver IC Compatibility
NCP files can only be generated for supported module driver ICs. When the end user switches to the COEX control system, or when the LED screen manufacturer designs a new cabinet, to use the NCP file, it is recommended to first check whether the driver IC is supported and then submit a request to NovaStar technical support engineers. If the driver IC is supported, NovaStar technical support engineers will perform the debugging process and
generate an NCP file as soon as possible. If the driver IC is not supported, NovaStar technical support engineers will escalate the request to NovaStar dev
team. Once the dev team is finished and the driver IC is supported, support engineers will then complete the debugging process and generate an NCP file.
