KIO3B usb com port not communicating

Hello,

I have KIO3B (USB interface) in my K3. It was working well. Single
USB for audio, and CAT.

Suddenly, now the CAT part is not working. Here are some aspects:
* RS232 in K3/Config shows USB
* Serial port 1 shows up in device manager on the windows computer when
the USB is plugged in. The sound codecs are working.
* Nothing communicates with the K3 CAT any more (K3 utility, and logging
programs do not see the K3 on the com1.)
* I tried it on a new laptop with a fresh USB cable. Exactly the same
issue.

Any help appreciated.

Raj, N2RD

On a Windows computer the USB com port will be something other than “1”.

Raj,

Try looking in Device Manager again. Which COM port goes away when you
unplug the USB cable from the computer? COM1 is normally reserved for
the motherboard serial port - which will be RS-232 and not USB. It will
be there whether it is connected to the back panel or not.

Then plug the USB cable back in - which COM port is assigned? Put that
COM port number into K3 Utility and try to connect.

Hello all, especially Don,

The last tip helped make progress. I unplugged the P3 connected via
the RJ45 jack and suddenly my USB/CAT came back to life.

And, this disruption is repeatable. Plug the P3 back and again it
stops working. Unplug, works again.

Now, I will look to see what is up with the P3. I checked the
firmware on the P3. It is running the latest.

Re: KIO3B usb com port not communicating

Raj,

Don't overlook the possibility that the RJ-45 jack could be damaged.
If you have ever accidently plugged the USB cable into that jack - it
almost fits, but will damage the RJ-45 jack.

Check the RJ45 jack very carefully. One of the wires might have bent slightly
and shorts out the adjacent wire. I have found that a few times when repairing
computer problems for friend & family

Re: KIO3B usb com port not communicating

Do you have BOTH plugs connected to the P3? You need to use the cable that has not one, but two DE-9 connectors - this allows the data to flow from the USB interface through the P3 and then back to the K3S. Without it, I would expect exactly the behavior you describe. In fact, I experienced exactly the behavior, which is why I know.

Be sure to use the double DE9 cable, not the one with just a single DE9.
