The KPA500 uses new Auxbus commands and is one-way only (KPA500 to K3). The K2 does not know about the KPA500 commands and cannot understand them. There will be a new release of the K3 firmware to support these features about the time the KPA500 starts shipping.
The K2 will work with the KPA500 just fine. This is a case where the best way to connect them would be to connect Key out from the K2 to the KPA500, and RF Out from the K2 to the KPA500's RF Input. The KPA500 detected bands and switches incredibly fast (you have to experience it to understand how fast), so you don't actually need anything else. This is also true for all other transceivers and even the K3 itself. So why would you want to connect the KPA to the K3 with the special cable? The new support features that Wayne has added to the K3 will make you wonder how you lived without them.
