K3S, P3 and USB Audio

[Paul Wilton]

I’m trying to set up a borrowed K3S plus P3 for a club contest using a laptop.  The problem I have is I don’t have the CBLP3Y cable to connect the K3S to the P3, I only have the E980297 cable that connected a K3 to a P3 (the single ended RJ45 to 9 way D).  

Question - if I connect up the K3S and P3 via serial, can I still use USB for audio?

That is, can I connect it up:

Using cable E980297     K3S serial port -> P3 XCVR connector

and using standard serial cable    P3 PC connector -> laptop serial port  

whilst still having the USB connector in place supplying the audio.



Initial experiments with this approach haven’t been very successful but it could be a myriad of computer/N1MM+ hassle obscuring it.

Paul,

I don't know whether you can use the USB soundcard provision of the K3S
while using some other RS-232 port connected to the P3 and through the
RJ-45 to RS232 'dongle' at the same time.  But my thought is that they
are separate, the soundcard function is just like any external USB
soundcard.

I think you *should* be able to do that, but just keep in mind which COM
port is connected to your USB to RS-232 adapter and which one is the one
in the K3S.  The USB port FTDI will likely still show up in the computer
Device Manager.  Note the COM port number and do not use it to connect
with N1MM.
Do not set the K3S RS-232 menu to USB, set it to 38,400 instead.

You might want to try something more simplistic than N1MM first (like K3
Utility) to verify that the PC to P3/K3 connection works.

Once you can verify communications with K3 Utility, then try N1MM.

Thanks Don.  I did some more experimentation this evening and managed to get both functions working OK. ie CAT via Serial and audio via USB
