Re: K3 Locked Up - MCU LD
Confirming, your computer "device manager" changes to show the comm port when you plug the USB end into the computer? (takes maybe 10 seconds).
And you set the K3 Utility to that comm #?
Directly to the K3, no P3 or any other equipment inline?
Will the computer talk to the P3 with the P3 utility?
Send me an email direct with the whole story, I have too many things going on.
Next would be pull the KIO3 digital board and check the little black cube chokes, they should be about 4 ohms (they can get popped open).
