After power-up, the unit scans the outputs and looks for connected display (sink) in
ascending order (1 through 8). The EDID from the first discovered sink is recorded in
internal memory and is passed on to the input source.

You can use any output to connect the splitter to another SP-HD-8A to expand the # of
outputs. This can be done to a maximum of three (3) levels deep.
