I think the device that communicates with the encoders is either machine specific, or specific to a few machines. That's how it was when I had a Janome something or other, - mine didn't work and when I called the company, they had me open the device and move a couple little jumper type things and then it worked on my machine....
So I think you would have to call the company and see if the current set up is compatible with more than one machine...
