The castle link software has all of the info to program all of castles products. The castle link, is a small piece of circuitry that connects via the same usb cable that the mm uses, to the reciever plug to enable programming of the item.

The mm has the casle link built in, so that the usb connection is made between the esc and the computer. All of the other castle products need the castle link for programming, such as the ccbec.
