[RTTY] Kenwood TS-850, soundcard interface & FSK

[Vtnn43e at aol.com]

Is anyone out there using a TS-850 and a soundcard interface for FSK? I would like to get on RTTY but am confused as to how to hook up everything together.

As near as I can tell all I have to do is use the following on the ACC2 13 pin Din plug; pin 3 fixed audio and pin 4 audio ground for audio to the interface. On the back of the rig there is a RCA connector for FSK in. Can I just use that and the fixed audio from the ACC2 plug?
 
I am referencing pages 20 and 27 28 of the TS-850 manual for the FSK wiring.

BTW, my interface is a Rigblaster PRO.

Any info on this will be greatly appreciated.
