I was amazed at how such a device would work as little documentation is provided up front. I hope my brief review helps. Think the same way as an unmanaged network switch, in the sense that all ports can receive data from the parent controller, but no more than 1 parent controller can exist at a time. Other commenters say that you should run a cable from your ARGB source (like the mobo ARGB header) to the DG_1 header in particular - I agree with this approach. Regardless, the incoming signal is duplicated as the outgoing signal for the rest of the headers (the DG_1 input is copied to DG_2, DG_3, ., DG_11, DG_12, like the output in the previous recommendation/example). Also good news! Looks like they've fixed the "loose header" issue reported by commenters (all fine and tidy).
