Stereo Coding Settings/Setup/Understanding HELP!

Trying to find some documentation on how to setup Breakaway Broadcast for use as a Stereo Coder/Processor. I need suggested I/O settings, processor settings and which jack do you use for the output to the transmitter? Line Out? Which channel? L or R? or both combined? or a digital output? I’m a newbie to software based Stereo Coding for FM broadcast and just trying to understand settings. I’m also assuming that a second soundcard is needed in our situation.

We are running both our Automation Software (Raduga) and Breakaway on the same PC. We plan on tapping the audio output of the automation software using our TB Santa Cruz soundcard. Then taking the line output of that card to the external Emergency Alert System box, then out of that back into our 192 Realtek Motherboard Soundcard and using it to inject the Pilot and then out to the TX Composite input.

Is there any documentation that will guide me through the process of settings, etc? Thanks for the help!
