How to send the RCFG file in NovaLCT

The RCFG is a Receiving Card Configuration file (.rcfgx), this file contains all of the parameters for your LED panel like your pixel count, refresh rate, and other data related to the image/color effect of the panels in order to correctly display an image on the LED panels. 

Sending an RCFG file to the panels is essentially a first line of defense to resolve any abnormalities in displaying a clear, uniform image. A few common scenarios of when panel(s) might need to be "flashed" is when panels stop displaying an image, but still light up (basically showing static), there is a brightness difference between panels, or the receiving card had to be replaced to name a few. 

Before you get started

The first thing to do is locate and ensure you have the correct .rcfgx file. This can typically be found on a thumb drive included with your system. If you're having trouble, Submit a Ticket with your panel model information and we'll get one over to you right away. 

TIP: If you're in a pinch, you can also do a readback of the RCFG file from a working panel.
