In short

The receiving card sits at the back of every cabinet: it takes in the data arriving over the network cable and distributes it to the modules through the HUB card. It handles grayscale processing, refresh rate, the storage of calibration data and the compensation of a faulty row. The type of receiving card decides how many pixels one cabinet can carry, how high the refresh rate can go, and whether colour accuracy holds up at low brightness.

Where does it fit in the system? Every stage of the diagram is clickable — it takes you to that category.

A LED-fal vezérlési lánca kiterítve: forrás, processzor, vezérlő, hálózati kábel és a panel hátulján a fogadókártya — The receiving card sits on the back of the panel — on the right you can see the network cable arriving at the cabinet. Illustrative image.

Port count is not a detail: too few and part of the wall stays dark, and afterwards only a change of controller fixes it. Always ask the quote to state how many cabinets sit on how many ports.
