All you should have to do is plug a modular cable from the autoguider output to the guider input on the CI-700 hand box. Make sure the cable is wired the same on both ends since some phone cords "flip" from end to end. Set the CI-700 to the .3x guide rate and find a guide star, focus, set up the software and start the autoguider.
I autoguide my CI-700 with a HX516 camera and SX interface and it works great. Hope this helps a little.
