What is an RCFGX file?

        
An .rcfgx file is a NovaStar receiving-card configuration exported from NovaLCT. It is a ZIP archive that stores an LED cabinet's complete setup — module and pixel geometry, driver-IC type, scan mode, gray depth, refresh rate, brightness, gamma and calibration. This free RCFGX viewer reads all of it right in your browser, with no NovaLCT install required.

Frequently asked questions

        
What is an .rcfgx file?
An RCFGX file is a NovaStar receiving-card configuration exported from NovaLCT. It is a ZIP archive that stores an LED cabinet's complete setup: module and pixel geometry, driver-IC type, scan mode, gray depth, refresh rate, brightness, gamma and calibration data.
How do I open an RCFGX file without NovaLCT?
Upload it to this free online RCFGX viewer. It parses the file in seconds and shows the cabinet's specifications and a visual module-layout map — no NovaLCT or any software install required.
What is the difference between RCFGX and RCCB?
An RCFGX is the ZIP/XML receiving-card configuration produced by NovaLCT, while an RCCB is the raw binary register dump it wraps. This viewer reads the human-readable settings stored inside the file.
Can I compare two RCFGX files?
Yes. Use the free RCFGX compare tool to upload two files and see exactly which settings differ, side by side, with the module layout drawn for each cabinet.
Is the RCFGX viewer free?
Yes, it is completely free to use and there is no sign-up required.
Is my uploaded file private?
Your file is uploaded over a secure connection and stored privately so our team can help and so you can revisit it later. It is never shared publicly.
