As far as I am aware, there is more then one way to integrate a Six Shooter with the CBIII.
First off, I believe that all of the Digi-input cards sold with a more recent version of the CBIII include the "Data" port, where the "Glass" option used to be. So depending on when you bought a CBIII or had one upgraded, you may or may not have a "Data" port. If it's there, nothing more then a Six-Shooter is required.
The other option that will work, as far as I know, would be to use the "vol" inputs on a Digi-out card. I've never done it but I believe this works just as well.
