[Elecraft] KAT500 and KPA500 integration

[ANDY DURBIN]

It's clear that both the KPA500 and KAT500 must be RS-232 transmitters as well as RS-232 receivers. If that were not true then the PC utilities could not function. My station data logger has been polling, and receiving responses from, my KPA500 since I first built it.


Now I know that the KAT500 will receive and process the Kenwood command set I think I can see how to implement a band control interface and still be able to receive KPA500 and KAT500 status with my logger.


What is still not clear to me is how the KAT500 uses the single line AUX bus. The KAT500 schematic shows the AUX bus is received as "AUXB" and not just passed from input connector to output connector.


Thanks to all who contributed to the discussion so far.
