The Transfer Board (also known as a Transfer Card) is an internal component that facilitates signal connections between LED modules and the cabinet. Note: Current models have largely transitioned to "3-in-1 Boards." This article is for legacy product maintenance and technical reference only.


Key Functions:

  1. Signal Supplementing: Routes processed video signals from the receiving card to individual LED modules.

  2. Module Interfacing: Mounted directly onto the cabinet to provide a physical connection point for module installation.

  3. Maintenance Diagnostics: In legacy systems, the Transfer Board is a primary component to inspect if local module display issues occur.

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.
