Optional PCB is also connected to HP via the CN-CNT ( in case using it and CZ-TAW1 ,Optional PCB is conected to HP , and on Optional PCB there is another CN-CNT to connect CZ-TAW1). In this way Optional PCB comunicate with HP in similar way to CZ-TAW1 - Next to(between) standard Magic Packets there specific commands from Optional PCB to HP ,and next to (beetwen) answers from HP there is a answer/confirmation to Optional PCB.
