Answer: The Transfer Board (aka Transfer Card) plays a part in supplementing LED Module signal connection. It is directly connected to the LED Modules and mounted onto a Cabinet as shown in Diagram 1 below.

The Transfer Board houses the Receiving Card. The Receiving Card does not need to be taken off to take off the Transfer Board. Similarly, the Power Board for LED module does not need to be taken off to take off the Transfer Board.
Signal is taken from the System Control box and sent to the Transfer Board, thus sending the signal to the Receiving Card, and ultimately distributing the signal across LED modules. Generally speaking, there are four LED modules per Receiving card as shown in Diagram 2 below.

Important Note: Transfer boards cannot be interchanged across models. If replacing a transfer board, please ensure the transfer board is designed for the correct size, resolution, and other specifications.
