NO! Do NOT use a 15 to 15 DE-15 with all wires connected! Or at your own risk...
You should only connect AUX, BND0-4, Key line and ground.

As far as I know AUXBUS just works one way (see the K3/KPA500 integration).

Yes, this is correct. You need a DB15HD M/F cable (SVGA cable) between the
K3 and KAT500, and the normal DB15HD M/F Elecraft-type cable between the
KAT500 and KPA500. The

There is no Y adapter necessary. Connect one Aux cable from the K3
