K3 - communication failure after KIO3B upgrade

Maybe the combined wisdom of the group will be able to help before I send
this to Elecraft support.

I installed the KIO3B upgrade in my K3. The USB interface from PC to K3
works but only if you don't plug a cable in the RS232/P3 jack. The RS232
connection to the P3 isn't happening -- no frequency info or VFO cursors
are displayed. Just hooking it up causes communication with the K3 to fail.
Even if the connectors to the P3 are left unplugged, simply plugging the
cable into the RS232/P3 jack causes communication to fail. If I try RS232
mode, the PC can talk to the P3 with the P3 utility, but cannot talk to the
K3.

There are some slightly different symptoms, depending, so here's more:

1. USB mode, CBLP3Y plugged into the K3 jack but not plugged into P3.
Starting the K3 utility yields the message "K3 waiting for firmware load."

2. If I plug the Y cable into the P3 and start the K3 Utility, it cycles
through baud rates and never sees the K3. The same happens if I use RS232
mode and connect the PC to the P3 and the P3 to the K3 with the
single-headed cable.

All firmware and utilities are up to date and I've double and triple
checked all the settings I can think of. I even re-opened the top to double
check the USB/RS232 switch on the KIO3B.

Any suggestions? I'm thinking that my digital IO board might be faulty.

Thanks,
Carl WS7L

Re: K3 - communication failure after KIO3B upgrade

Carl,

A couple of thoughts.

1) Losing communications with the Y cable plugged into the KIO3B but not
having BOTH DE-9 connectors attached to the P3 will result in no
communications. The KIO3B senses the Y cable and routes the USB side
communications to the P3 which then routes signals to the K3.

2) Be sure the cable is fully seated into the jack on the KIO3B. The
plastic lock should "click" into place. You can verify this with a
gentle tug on the cable after it is inserted to verify it is fully seated.

3) Be sure the P3 is set to 38,400 bps on its serial ports.

4) If the cable is fully seated and the P3 is set to 38,400 bps and you
still have the problem, I'd suspect the Y cable being defective. I
don;t know if the schematics for the cable are on the website or
supplied with the cable to assist you in troubleshooting the cable if
you so desire, so it may require a call to support on Monday, or an
email directly to them.

73,

Lyle KK7P

Re: K3 - communication failure after KIO3B upgrade

Thanks Lyle. I tried those things. If it's a cable problem then I must have
TWO defective cables, because feeding RS232 to the P3 and connecting the
single-headed cable to the K3 also results in no communications to the K3.
And yes, I put the K3 in RS232 mode at 38400 baud when I tried that.

Hi Carl

Have you actually set RS232 to USB in the Config menu ? Just a thought.

Re: K3 - communication failure after KIO3B upgrade

Steve AD7OG graciously permitted me to tear his K3 apart and swap boards.
KIO3B main board is bad and Elecraft is sending a replacement.

73 - WS7L, whose K3 #486 after 8 years of service just keeps getting better!
