[Elecraft] KPA500 firmware load fails?

[David F. Reed]

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).

Thanks & 73 de Dave, w%SV
