Abstract

A connector interface system for a communication device is disclosed. The interface includes a docking connector. The docking connector includes first make/last break contacts that minimize internal damage to the internal electronics. The docking connector also includes specific keying arrangement to prevent noncompliant connectors from being plugged in, and thereby minimizes potential damage to the multi-communication device. The connector interface system also includes a remote connector which provides for the ability to output audio, input audio, provides I/O serial protocol, and to provide an output video. Embodiments of the present invention allow for a standard headphone cable to be plugged in but also for special remote control cables, microphone cables, video cables could be utilized in such a system. The connector interface system also includes a serial protocol to control device features. These controls help a user sort and search for data more efficiently within the device.
