KIO3B USB Question

If I am reading correctly in Fred's book. I can connect the *CBLP3Y
cable to a USB to RS232 adapter to my computer which would create a
second comport from the radio to my computer. For example (if I am
reading correctly)*

*The USB port could be used to for audio codec and rig control (which I
am already doing successfully)*

*The RJ45 comport output could be sent to a computer to send freq/rig
data to an SDR receiver for example.*

*Is my thinking/reading correct?*

*This seems very straight forward, but I was hoping to get some thoughts
from others before I try it.*

*Thanks*

*Rich*

Re: KIO3B USB Question

Rich,

Not quite. You do NOT want to connect the CBLP3Y cable to a USB to
serial port adapter. You will not only have communications failures,
but you may damage the K3 USB port output and the USB to serial adapter
because you will have two drivers on the same RS-232 signal lines.

I assume you have a P3 since you have the CBLP3Y cable.

You can connect a simple RD-232 Y cable to the PC port on the P3 with
the CBLP3Y cable plugged into one side of the Y and the serial cable to
your SDR receiver on the other side.

Your SDR receiver must turn its driver off - it can listen to the RS-232
traffic, but it cannot transmit requests or commands.

You may have to set up virtual ports with LP-Bridge or Com0Com.

Re: KIO3B USB Question

Thank you. I thought I found a way to use the USB port for audio/rig
control and the other for sending Freq data to the SDR.

I guess not.

Thanks again

Rich

Re: KIO3B USB Question

Rich,

The RS-232 lines in the K3 are essentially the same as the lines to the
internal USB adapter.
That means that they are NOT two separate ports.

Yes, using the serial dongle that comes with the K3S or the KIO3B
upgrade for the K3 does allow you to use an RS-232 port or USB adapter
to connect to the K3, but you must move the switch on the back of the
KIO3B in order to do that.

You would have to link the two com ports using a computer application,
and I don't know of one that will do that.
i.e. take the COM port data from the K3 USB 'COM' port and feed it to
the port that connects to the SDR.
As I recall, LP-bridge may have that capability, but it rather complex
and I have not studied it.
