This product is designed to replace a CB1 that no longer works, or has been lost in a move. In other words, what you have no longer functions. Replacement CB-1's are very difficult, if not impossible to find, so along comes the CB2.
DesignaKnit owners can still use DAK on their KH-970 with this CB-2 Control Box. The CB-2 DesignaKnit Link option is already built in and ready to go if you have DesignaKnit. If you purchase DesignaKnit, then you're all ready to go. No problems. In any case, because the CB-2 is hooked up directly to your PC, you no longer need a cable and a magnetic switch such as the Brother cable link BL5-USB.
Note: pattern transfer from DesignaKnit to the CB-2
cannot be done with the
Brother Link 5 (USB). This can only be accomplished with the CB-2 Cable and Control Box
