I think it pretty much doesn't matter what pins you use (unless you have pre-wired connectors attached to pixel...
From the description, it seems like any time it receives data on the DIN it compares it with the BIN and, if there is a difference it sets a flag to ignore the DIN and use the BIN instead. So if a pixel goes dead and doesn't forward data out, it is removed from the sequence and the sequence is...
