[1000mp] Sound card interface

[MG]

Hello to everyone,

many months ago I made this sound card interface:

In RTTY mode, with my FT-1000 MV Field, it works fine; now I would like 
to transmit in other digital modes, as PSK31.
I can not do it, I do not understand in what mode I have to set my rig. 
I wired all the sockets of the radio and computer, as in the project, of 
course.
I think that interface is able with all or most used digital modes, have 
I been wrong something?
