The dock connector was introduced with the 3rd generation iPods. With the dock connector the iPod can be charged, connected to a PC via USB or Firewire, connected to a stereo via line-out or connected to a serial device and controlled via the [[Apple Accessory Protocol]]. The manufacturer of the dock connector is [http://www.jae-connector.com/en/index.cfm JAE]. The manufacturer's information on the dock connector can be found [http://www.jae-connector.com/en/general_en.cfm?series_code=DD1&contact_number=&s_height=&l_con=&r_con= here]. ==Dock Connector Pin Out== [[Image:Pinout cable end.png|thumb|300px|Pin 1 is on the right side of this image, taken from the manufacturer's website.]] [[Image:IPod dock connector 032.jpg|thumb|300px|Pin 1 is on the right side of this image. This USB cable only has pins 4, 6, 8, and 15 to communicate with USB's four pins.]] [[Image:IPod mini pin 1 marker.jpg|thumb|300px|Pin 1 marker on the PCB for an iPod mini. The camera is facing the back side of the iPod.]] The female dock connector's pin numbering: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 The male dock connector's internal pin numbering: 1 3 5 7 9 11 13 15 17 19 21 23 25 27 29 2 4 6 8 10 12 14 16 18 20 22 24 26 28 30 === Pin#/Functions === '''Note:''' The pin ordering here may be reversed on your breakout board or dock connector. Doublecheck with your dock connector manufacturer for clarification. The order shown here is in-line with one of the manufacturers, but not others. Be aware of this, as connecting it backwards might damage your iPod. # FireWire Ground ^{[[#fn_FWGND|1]]} # FireWire Ground ^{[[#fn_FWGND|1]]} # FireWire Data TPB (+) # USB Data (+) ^{[[#fn_USBD|2]]} # FireWire Data TPB (&minus;) # USB Data (&minus;) ^{[[#fn_USBD|2]]} # FireWire Data TPA (+) # USB VBUS Power +5 VDC (from computer) ^{[[#fn_USBD|2]]} # FireWire Data TPA (&minus;) # Accessory Indicator ^[[#fn_AI|3]] # Firewire Power +12 VDC ^{[[#fn_FWPWR|4]]} # Firewire Power +12 VDC ^{[[#fn_FWPWR|4]]} # +3.3V Power (to power iPod accessories) ^{[[#fn_3.3V|5]]} # &nbsp; # USB GND ^{[[#fn_GND|6]]} # Ground ^{[[#fn_GND|6]]} # &nbsp; # Serial RxD # Serial TxD # Serial GND # S-Video Luminance ^{[[#fn_SVid|7]]}, Component Pr # S-Video Chrominance ^{[[#fn_SVid|7]]}, Component Y # Video Out - Composite Video (for ipod colour when slideshow activated)^{[[#fn_VidOut|8]]}, Component Pb # &nbsp; # Line In - Left # Line In - Right # Line Out - Left # Line Out - Right # Line Out - Common Ground ^{[[#fn_AudioGND|9]]} # Ground ^{[[#fn_AudioGND|9]]} * <cite id="fn_FWGND">Note 1:</cite> Pins 1 and 2 connected on motherboard * <cite id="fn_USBD">Note 2:</cite> 4 and 6, D- and D+. Different kind of behaviour of the iPod if those pins are set to a certain state: ** To force the iPod (useful for the iPod 5G) to charge in any case, when 'USB Power 5 VDC' (pin 8) is fed, pin D- must be connected to 3.3V (USB uses 3.3V for data communication, you can connect to 5V but its not as safe) through a 10k&Omega; resistor, and pin 4 must be connected to the Ground (for example: pin 1) with a 10k&Omega; resistor. 10k&Omega; resistor has been determined experimentally. ** To force the iPod nano 2nd generation (aluminium case) to charge, you have to connect pin 6 to 5 VDC (pin 8) through a 10k&Omega; resistor while leaving pin 4 unconnected. ** To properly charge iPod nano 2nd generation, connect pin 6 to 2.5 VDC through 10k&Omega; resistor, while pin 4 receives 2 VDC. ** To charge your video iPod, and play at the same time, connect +12V to pin 11 (Firewire +12). Useful for car iPod players. Also when the car 12V accessory socket turns off when the ignition switch is turned off, this will turn the iPod off. * <cite id="fn_AI">Note 3:</cite> Pin 10 connected to ground via a resistor. Different resistances indicate which accessory is connected. Known resistances/functions (ohms) are as follows: ** 1k&Omega; - iPod docking station, iPod beeps when connected ** 10k&Omega; - Takes my iPod into photo import mode ** 500k&Omega; - ''vava'' uses this for his serial-via-dock experiments. Used in Dension Ice Link Plus car interface ** 550k&Omega; - Measured value of Nike+ Receiver ** 1 M&Omega; - Belkin auto adaptor, iPod shuts down automatically when power disconnected * <cite id="fn_FWPWR">Note 4:</cite> Pins 11 and 12 connected on motherboard * <cite id="fn_3.3V">Note 5:</cite> Pin 13 stepped up to provide +5 VDC to USB on iPod Camera Connector. ** If iPod is put to sleep while Camera Connector is present, +5 VDC on USB slowly drains back to 0 VDC. ** If Camera Connector is disconnected, draining power can be detected between this pin on the Camera Connector dock connector and +5 VDC on USB connector. ** Used by the [http://nuxx.net/wiki/Honda_/_Acura_Music_Link_%28Technical%29 Honda Music Link] to detect the presence of an iPod. * <cite id="fn_GND">Note 6:</cite> Pins 15 and 16 connected on motherboard * <cite id="fn_SVid">Note 7:</cite> Newly discovered from iPod Color Dock * <cite id="fn_VidOut">Note 8:</cite> Composite out uses common ground as ground * <cite id="fn_AudioGND">Note 9:</cite> Pins 29 and 30 are connected on motherboard ==Where to order Dock Connectors== *[[User:Ridax|ridax]], one of our forum members, has purchased a bulk amount of dock connectors to resell to hobbyists.
