Daisy chained Renards look like a single controller to Vixen.
Each PX1 will grab all of the channels it is configured to grab and pass the rest of the data to the next controller (even if there is no next controller).
The PX1 will output data for all of its configured channels even if there are no LED Pixel strings attached to the controller.
If you connect 10 pixels (note I am NOT saying string since it is not a relevant term) to each PX1 then the data for the first 10 pixels assigned to each device will get displayed.
Each PX1 has a 'single' string attached to it. This string should be the same length as the configuration entered into the PX1. If more pixels are present then the remaining pixels will be in an undefined state. If fewer pixels are present then the extra data sent from the PX1 to the pixels will be discarded by the last pixel.
