[Yaesu] DVS-2 connector questions...

[bill K7WXW]

I would like to use digital modes with my FT1000D. I know I can make a 
cable and use the mic input but that's inelegant and a pain, besides. I 
guess I could also build a cable that uses the phone patch, AF out, PTT 
connections but that seems a kludge.  Packet only does FM and LSB, and I 
haven't figured out a way around that, so the packet connector is out.

But there's the DVS-2 "Voice" input. Since it has audio in, audio out, 
and PTT, and the audio chain looks okay for AFSK, I am trying to figure 
out what the two control lines do. I can't quite figure it out by 
looking at the FT1000D schematics, so I currently have three questions:

- Does anyone have a schematic for the DVS-2?
- Does anyone know what the control lines do and their electrical 
characteristics?
- Has anyone used the DVS-2 interface for anything other than a DVS-2?

Thanks in advance for any help or guidance offered.
