[amsat-bb] LVB cabling?

I just ordered my LVB box from Amsat as one of the final pcs. necessary to finish building my base station.  I know a CAT cable is needed from my 847 to the computer, but what is required from the computer to the LVB box and from the LVB to the rotator control box?  For this installation, I plan to use a Yaesu 450 for azimuth only movement along with a Gulf Alpha dual band at a fixed 15* elevation.
