I might be wrong (I often am!) but I believe that this stitch regulator goes on the frame, not the machine, so you could not use it with just the machine.
The way frame stitch regulators work is there are encoder wheels that ride on the tracks and detect how you are moving the machine (not the fabric). The info from the encoders goes into your computerized machine and regulates the stitches. There's no way for the encoders to work without the frame. what you may have read is that this setup talks to your machine.
