Your LED screen is made up of a variety of components. I'll walk through the key pieces within your system and specific items within your cabinet that you'll need to know about during your installation. First off, the cabinet is the makeup of the entire elements you see right here. The cabinet includes the housing, which has the handles and your various machining for bolts and screws. Within the cabinet, you have thumb screws. This is your initial attachment point for the cabinet surrounding. You simply screw these and push them into the next cabinet, and you'll tighten them by hand first, and then move into a final tighten with an Allen wrench tool. Also, within each cabinet are orientation arrows. You have an arrow pointing up here, as well as on your hub board here. Orientation does matter and these arrows need to face up. Over here is the power supply. The power supply is what is gonna power the LED screen modules that will be placed at the last step, and it also provides power to the receiving card. This is the hub board, which includes the points of contacts for your modules, as well as where your data will flow in and out from. Inserted onto the hub board is the receiving card. The receiving card is a separate board that's attached to the hub board which talks with the processor. To connect data to your screen cabinets, you'll utilize data cable which connects in and out of these ports. Each port orientation as far as in and out does not matter. You can go in or out of the bottom or in and out of the top. We like to use a top down method, meaning your input side is the top and your output side is the bottom. Keeping things consistent will help you troubleshoot things down the road. The pin connectors here is what the modules will attach to. We'll show you that in a moment when we attach the module. At the bottom of the cabinet are the power daisy chain cables. You'll take these and route them between each cabinet to daisy chain power between them. The orange is a locking connector, which to release, you'll need to simply press.
