Used in 3rd and later generation iPods for charging, connecting to a PC via USB or Firewire, to a stereo via line-out, to a serial device (controlled via the Apple Accessory Protocol). This connector exists in most Apple iPod MP3 players (iPod 3G, 4G, 5G Video, 5.5G Video, Nano (1G, 2G, 3G, 4G), Mini, Classic, Touch, Touch 2G, and iPhone (1G, 3G and 3GS)) Pin

Pins 25 and 27 may be used in different manner. To force the iPod 5G to charge in any case, when USB Power 5 VDC (pin 23) is fed, 25 must be connected to 5V through a 10kOhm resistor, and 27 must be connected to the Ground (for example: pin 1) with a 10kOhm resistor. iPod 5G can also be forced to charge by attaching the data + and the data - pins to the 5v via a 10k Ohm resistor ( BOTH PINS) and connecting pin 16 to the 5v (ground). (Confirmed working with iPod 5G 20GB). This provides 500mA of current for charging. For quicker charing, up to 1A, see below.

Data (+)
To charge an iPhone, 3G, 3GS, 4 / iPod Touch, 2nd gen, 3rd, 4th or Ipod Classic (6th Gen), usb data- (25) should be at 2.8v, usb data+(27) should be at 2.0v. This can be done with a few simple resistors: 33k to +5v (23) and 22k to gnd(16) to obtain 2v and 33k to +5v and 47k to gnd to obtain 2.8v. This is a notification to the iphone that it is connected to the external charger and may drain amps from the usb. To charge iPod Nano pins 25 and 27 should be tied together and then connected to a 10K ohm resistor, and the other side of this resistors then needs to be connected to 5v power. It's also possible to charge the iPod's or iPhone's battery to make use the of internal +3.3v output (18) terminal to connect the USB Data + (27) thru a 47k ohms resistor and the USB Data- (25) thru a 47k

connector-cable and look at the connector itself, on the back side, where it is soldered, you can see the number 1 and 30 (e.g. pin 1 and 30). In this description NUMBERING is INVERSED: pin 1 is pin 30 and pin 29 is pin 2, so, don't look at numbers on connector. The remote control, iTalk and other serial devices use Apple Accessory Protocol for communication with iPOD. This protocol was introduced with the 3rd generation iPods, and is also compatible with the 4th generation iPods and mini iPods. The connections uses a standard 8N1 (one startbit 8 data bits 1 Stopbit) serial protocol, 19200 baud (higher rates up to 57600 also possible, but speed faster than 38400 may cause problems with large amounts of data), delay of 12 microseconds inserted between end of the stopbit and the beginning of the next startbit (also working without this delay). Electrical: high +3,3V low 0V default line state: high. Codes used for communication with peripherals are here This device may be connected to the firewire computer port by straight cable (TPB+/-, TPA +/- should be twisted pairs in cable)

iPod Nano 4th Gen no longer will charge from 12 volts on the firewire pins. If you tie pins 25 and 27 together and then connect a 10K ohm resistor to +/- 5 volts to pins 23 and 15 (or 16) then it will charge. If you don't tie 25 and 27 together, it won't charge. iPod Touch 3G: may also require for pins 1 and 2 (GND and audio out GND) to be connected in order to output audio (pin 11 to GND). Works with appr. 500 kOhm between pin 21 and GND. iPod Touch 2G requires pin 11 connected to 15/16, then connect that to pin 21 with a 68kOhm resistor to use the audio line out. This is because the device needs to be told to redirect the signal to the Line Out pins rather than to the built-in speaker. This explains why certain accessories won't work with the iPod Touch 2G and maybe even the iPod Touch 3G. The Nano 5G will require the pin 11 connection but not the 68kOhm resistor for redirecting audio. Nano 5G: connecting the 68kOhm resistor to ground will disable the audio redirection accomplished by connecting pin 11 to ground. You may need to ensure 1 and 2 are connected to GND for proper charging to occur.
