I hope for your sake that the serial cable wasn't a 9 pin through.  Look at your assembly manual, or download the PDF file from the Elecraft site.   It describes which pins need to be connected for RS-232 connectivity.  The K2 uses other pins for its control.  The manual is very specific, and warns of possible damage if a straight through 9 pin serial cable is connected directly.

You are most likely correct in assuming that the USB to serial cable is the source of the problem.  I use a USB to serial adapter and have built a serial cable which conforms to the Elecraft standard which works well.

Elecraft doesn't sell a serial cable.  But on the bright side they are easy to make and inexpensive.  

To test if you have damaged any of the KIO components does the KAT100 tuner work when the serial cable is not installed?  For that matter assuming the KPA-100 is mounted to the K2 does it work?  If you do have a problem it should be fairly simple to isolate and repair.  

Good luck,

Subject: [Elecraft] from John kb3hqh

first of all I want to thank everyone for replying to my question.  I should have told you how I hooked it up.  I have the regular k2 cable that interfaces with the antenna tuner, then goes into a long cable with the serial connector.  so it has three serial connectors.

I plugged a radio shack serial port to usb cable into the female connector that goes to the computer and thenthe usb connector into my computer.  I had already installed the software for the Radio Shack cable.  

Then everytime i ran the software (n4py) , my computer crashed and rebooted itself.  Did the software get corrupted in the radio control program, or was the radio shack serial port to USB cable not the right cable to use?

And what kind of cable the Elecraft sell.  Does it have the three serial connectors on?  Then where is the USB connector?  Or does it have two serials and one USB conector.

Reinstalled the software and it worked fine for the jupiter.  Did not try it again with the K2.

Looking for some feedback.  Hopefully I did not damage the rig.

The rig operates fine now though.
