The two serial connectors on the KPA500 are for connection to a PC and a Kenwood radio for its band information. There's no RS-232 passthru there, either...

Thanks Don; so I assume that means that I cannot daisy-chain the RS-232 port from the PC to the KPA500 to the K3? It sort of looks like I should be able to from the way the back of the KPA-500 is labeled by the two serial ports. Is that correct? (I understand the KAT500 is on its own serial port).
