Computer will not speak to K3


KX2A
 

A week ago, I used my K3 with my computer logging program, Logger32, successfully.  Shortly thereafter, I had a problem with the logging program and had to reinstall it.  Following that, I was unable to communicate between Logger32 and the K3.  I have the I/O board that has a USB connector.  For a while, I was sure that Logger32 was at fault, but finally I decided to try K3 Utility just to assure that there was communication.  There was no communication.  I have tried the Auto position in K3 Utility, but no confirmation of communication results.  I have pulled the USB cable out of the the computer and replaced it, and then did this with the K3, and in both cases, the computer beeps to say that a cable has been removed and then beeps to say it is back in.

I do not know if there is a command or switch that I have forgotten.  Prior to this, the rig has worked with computer for about three years, when I put the USB board in.

I am certain that I have the correct COM port, but I have tested all of those listed in the K3 Utility (1, 3, 5, 9).

I just looked at the K3 Utility Help,and it indicates that the correct port, in Device Manager, should mention an FTDI chip.  The port that I think is the right one says it is a USB serial converter, manufacturer is FTDI.

I do not know where to go from here?  Can someone help?

Dave,

I am running Windows 10 Pro.  The latest Windows Update was a Quality Update, 7/24/2020.  The latest Driver Update was 4/16/2020.  The latest Definition Updates 7/24/2020 to 8/6/2020.  I believe that the Definition Updates were occurring at the time that the failure became known.  Google indicates that Definition Updates are related to Windows Defender.  I am using AVG anti-virus, but Windows Defender still appears to be running as a firewall.  I do not see how this would cause my problem, but I am open to suggestions.

Thanks,
Jan, KX2A

Start by unplugging the adapter while watching Device Manager.  The COM device that dissapears and reappears is the correct device, with its COM port noted.  Make sure no other software is open and using that port.

If still no luck, consider trying another USB to serial adapter in case that one was damaged.
