After many trials and tribulations I finally figured out how to interface the FT-1000MP Mark V with my homebrewed digital interface to my homebrewed computer. The following information will allow you to use the "Packet" DIN jack on the back of the rig for "AF" PSK, MFSK16 and RTTY.

As far as wiring:

1.) Transceiver audio out to soundcard in is via pin #4 (Data Out). 

2.) Transmit audio in from soundcard to pin #1 (Data In).

3.) If you want to use PTT actuation from your computer to transceiver then it's pin #3 (PTT). You could also skip the T/R switch and use VOX but I don't like to do that because the VOX settings for phone and digital are different.

As far as setting the transceiver up for use of the Packet DIN jack on back and the PKT mode button on front:

#1.) Push fast button and hold then the ENT button.
#2.) Select menu item 8-6.
#3.) Using the sub VFO tuning knob go to Easy Set.
#4.) Using the main VFO knob select PS31-u.
#5.) Hit ENT button.
#6.) Press PKT button once and the green LED on the LSB button lights up.
#7.) Press the PKT button a second time and hold for 1 second, you hear a beep and Voila you are in USB mode 
even though the LSB LED remains lit. 

You can check that you are indeed in USB by going to 20 meters and tuning in a phone signal.
