Hi Tony - I have the PROII.  On page 20 of the manual is a diagram for
connecting AFSK - can be used for RTTY and PSK.  It shows pin 1 being used
for -FSK- RTTY keying.  It's -NOT- for audio input!

AF input (AFSK RTTY or PSK, or HELL, MFSK16 etc) is pin 4.  Ground is pin 2.
AF out is pin 5.

I don't see anything about "mod".

Hope this helps!  73 - John, WA9ALS
