The articles in the following links may help to understand the differences between an RJ11 and RJ12 (or 14 or 25) connector, or not! However, in the interest of simplicity, Midon Design has chosen to refer to the connectors used on our products as RJ11 for a 4 pin device and RJ12 as a 6 pin device.
