LewanSoulBusLinker TTL/USB Debug Board for LX-16A Bus Servo

I don't see a bus cable in the pictures. Does this package come with one?

can these be programmed by "read angle" (manually) like the LX-15D ?

where can I find a link to download pc software?

how many servos can I control with this board? If only one, which board do I use to control more than one? Any sample software available?
