My current setup is K3S, P3, KPA500, KAT500
I recently replaced my K3 with the K3S. I was able to run all the utilities 
with no problem when I had the K3. 
Now, the K3S and P3 utilities are fine. But not so withe the KAT and KPA ones.
Both take several minutes to come up and run.

KAT500 utility: can’t connect (KAT500 not responding)

KPA500 utility: connects at 38400 no problem but no info shows in the operate 
tab. firmware N/A. I try to load firmware and it fails. I tried to force a load 
(per the manual) with no luck.

More info:
The K3 is set to USB.
The computer is an Apple mac mini with the latest OS.
I’ve refreshed the ports before trying to connect.
I’ve tried rebooting, unplugging  and replugging the USB cables.
I’ve checked all the cable connections.

Note that all units are operating OK except:
On 6 meters, the KPA faults when trying to run more than 200 watts. 
It used to work fine when I had a K3 driving it.

Any suggestions?
TNX and 73,
