Replace the receiving card of LED display

Receiving card plays an important role in the synchronous led display systems. It keeps reading the program command from the sending card or the computer.
But sometimes, though it's quite rare, the receiving card may fail. And when the problem detected is certain the receiving card, you need to replace it with a new one.
The replacement process is very easy - you could just turn off the power of the led cabinet with this receiving card, disassemble the screws, take out the receiving card, assemble the new receiving card and plug the cables accordingly.
When you turn on the power of the cabinet with the new receiving card, it would show something not correct, please refer to below picture.

That's because the receiving card is not configured. If you have the experience in using led displays, you would know that the .rcg file(of LINSN) or the .rsps(of DBSTAR) is not loaded. And these "intelligent" files are in fact a quick method to "build a communication bridge" between the control system and the led display modules.
So after you've replaced the receiving card, you need to upload the "intelligent" files to the receiving card.
If you're using the LINSN control system, please refer to this link to upload the .rcg file to the receiving card;
If you're using DBSTAR control system, please refer to this link to upload the .rsps file to the receiving card.
But always remember: the "intelligent" files is very important, so whenever you bought the led display, you must keep the files copy. What to be noticed is - if the files are lost and you couldn't get it from the original led display suppliers, things would be a little complex because this is related with the led display product design - and different led display manufacturers may design their product different.
The experienced engineer could create the files with a online remote assistance, but this will cost hours of time.
