My use has nothing to do with software drivers that may or may not be associated with RS-232 devices connected to the computer.
I hope I did not confuse anyone. 73, Don W3FPR On 2/24/2012 5:19 PM, Don Wilhelm wrote: > Jim, > > Remove the RS-232 cable to the KPA500 - it needs to be on a port that is > different (or not connected at the same time) from that used by the K3. > The KPA500 port is only used for firmware updates. > > In fact, since the KPA500 and the K3 both contain RS-232 drivers, they > will get confused and not work properly if connected together.
