Dock connector

Kansas is an American rock band that became popular in the 1970s initially on album-oriented rock charts and later with hit singles such as "Carry On Wayward Son" and "Dust in the Wind". The band has produced nine gold albums, three multi-platinum albums (Leftoverture 6x, Point of Know Return 4x, The Best of Kansas 4x), one other platinum studio album (Monolith), one platinum live double album (Two for the Show), and a million-selling single, "Dust in the Wind". Kansas appeared on the Billboard charts for over 200 weeks throughout the 1970s and 1980s and played to sold-out arenas and stadiums

Dock connectors can be used to interface with accessories such as external speakers, including stereo systems and clock radios. Automotive accessories for mobile devices include charging cradles, FM transmitters for playing audio through the car's speakers, and GPS receivers. There are dock connector cables that offer additional capabilities such as direct integration with the car's audio system and controls.

A dock connector is a connector used to attach a mobile electronic device simultaneously to multiple external resources. The dock connector will typically carry a variety of signals and power, through a single connector, to simplify the process of docking the mobile device. A dock connector may be embedded in a mechanical fixture used to support or align the mobile device or may be at the end of a cable.

The Samsung Galaxy Tab and Galaxy Note 30-pin dock/charging connector is very similar to - although not identical with - the non-proprietary PDMI connector. It is unrelated to the Apple 30-pin connector.

The Portable Digital Media Interface (PDMI) is a 30-pin interconnection standard for portable media players. It was developed by the Consumer Electronics Association as ANSI/CEA-2017-A, Common Interconnection for Portable Media Players in February 2010. The standard was developed with the input or support of over fifty consumer electronics companies worldwide.

Apple's proprietary 30-pin connector was common to most Apple mobile devices (iPhone (1st generation), iPhone 3G, iPhone 3GS, iPhone 4, iPhone 4S, 1st through 4th generation iPod Touch, iPad, iPad 2, and iPad 3) from its introduction with the 3rd generation iPod classic in 2003 until the Lightning connector was released in late 2012. Originally, the Apple dock connector carried USB, FireWire, some controls and line-level audio outputs. As the iPod changed, so did the signals in the dock connector. Video was added to the connector. FireWire was phased out of the iPods, which led to a discontinuity in usage of the dock connector.

As a result of the popularity of Apple's iPod and iPhone devices using the connector, a cottage industry was created of third-party devices that could connect to the interface. With the discontinuation of the sixth-generation 160 GB iPod Classic and the iPhone 4S, the last Apple products to feature the original 30-pin connector, the connector was discontinued in September 2014.

Docking connectors for laptop computers are usually embedded into a mechanical device that supports and aligns the laptop and sports various single-function ports and a power source that are aggregated into the docking connector. Docking connectors would carry interfaces such as keyboard, serial, parallel, and video ports from the laptop and supply power to it.

The 2001 Korean Telecommunications Technology Association (TTA) "Standard on I/O Connection Interface of Digital Cellular Phone" defined a 24-pin electromechanical interface specifications for cellular phone charging, wired data communication, analog audio, etc. The 2007 updated version has only 20 pins but added composite video output support among other changes.

Apple introduced an 8-pin dock connector, named Lightning, on September 12, 2012. The iPhone 5 and later iPhone models, iPod touch 5th generation and later, seventh generation iPod nano, every iPad mini, iPad (4th generation) and later, and iPad Pro all use the Lightning connector, as do several Apple accessories. Apple Lightning connector pins can be accessed from both sides of the connector allowing insertion with either side facing up. The Lightning connector replaced the 30-pin dock connector used by previous generations of iPods, iPhones, and iPads.
