0:11000000 - first...

2:00100000 - third...

0:10100000 - first...

1:01100000 - second...

0:11100000 - first...

That seems to fit for the quoted portion of the OP. Again, assuming we start with a returned zero being "first" channel, and count up from there. I'm not intentionally trying to be dense, I'm just tired, so it seems to fit the bill for what they're asking for. If it's not, someone point it out to me, because I'm just not seeing it.
