Do they mean that one goes into the power line adaptor and the other goes into the Freesat box with the cable for the other box coming out of the second splitter in the Freesat box.No. Lets try one more time they won't help in your particular case. They are used typically where you have a long ethernet cable and you want two devices at the far end. You have one "splitter" at the router end and you connect two ethernet cables from the "splitter" to different ports on the router. At the other end of the cable you have another "splitter" and you connect two ethernet cables from the ports on the splitter to the two different devices. It would be better called a combiner as it is really combining the signals for two ethernet cables into one.
By the way the switch that I have suggested is not a physical switch; you can use all the connected devices simultaneously (the "switching" is purely electronic and internal to the switch).
Exact and correct.
