It isused to connect the iPod or iPhone to various devices:PC (via USB or FireWireIEEE1394), audio amplifier, serial device (controlled via the Apple AccessoryProtocol).Pin Signal Description1 GND Ground (-), internaly connected with Pin2 on iPod motherboard2 GND Audio and Video ground (-), internaly connected with Pin 2 on iPodmotherboard3Right Line Out - R (+) (Audio output, right channel)4Left Line Out - L(+) (Audio output, left channel)5Right In Line In - R (+)6Left In Line In - L (+)8Video Out Composite video output (only when the slideshow mode is active oniPod Photo)9S-Video Chrominance output for iPod Color, Photo only10S-Video Luminance output for iPod Color, Photo only11GND Serial GND12Tx ipod sending line, Serial TxD13Rx ipod receiving line, Serial RxD14NC15GND Ground (-), internaly connected with pin 16 on iPod motherboard16 GND USB GND (-), internaly connected with pin 15 on iPod motherboard17 NC183."3V3."3V Power (+)Stepped up to provide +5 VDC to USB on iPod Camera Connector.IfiPodisputtosleepwhileCameraConnectorispresent,+5VDCatthispinslowlydrains back to 0 VDC.19,20 +12V Firewire Power 12 VDC (+)21 Accessory Indicator/Serial enable Different resistances indicate accessorytype:1KOhm - iPod docking station, beeps when connected10KOhm - Takes some iPods into photo import modeIMOhm-Belkinautoadaptor,iPodshutsdownautomaticallywhenpowerdisconnectedConnecting pin 21 to ground with a 1MOhm resistor does stop the ipod when power(i.e.Firewire-12V) is cut.
