Abstract
An electronic device includes an analog connector and a digital connector. The analog connector has one or more analog signal contacts and at least one other contact. A signal detector detects signals at the other contact. A switch is coupled to the other contact to, where analog signals are at the other contact, to cause the switch to transition a connection to other contact from a common node of the device to a signal node of the device, thereby allowing a user to use either a four-wire accessory device or five-wire accessory device with a four-wire analog connector.
