If we get a raspberry pi and set it up with xlights can we plug into the pixie controllers into the network jack from the pie or do we need the usb to serial adapters for the pixie 16's? Also we have two 16 channel pixies that will run a 16x96 matrix each, I read that if we daisy chain them that the matrixs don't display properly or lag? So Whats the best way to set up 4 Pixies? Thanks!
