RTTY with K3 like the K3 Utility

[dh4jq]

Good morning

 

I have a small problem I will use N1MM with my K3 for RTTY but only I will connect The K3 about the USB Interface at the time I work with  the K3 Utility works good

 

Can please anyone  write my what must I configure into the N1MM  to work RTTY only with the USB cable or is it not possible

 

Thanks for your help
