I think it would be much easier and faster to just connect all tre wires in
the cable together with the same wire in the other calcs.. no extra
hardware...
and then use something like the I2C protocol.. (by directly access the link
port)
that must be most simple both in programming and hardware.. almost no
hardware needed and just a little bit of programming...
