Connector pinout for: Apple iPod, iPad and iPhone dock

30 pin connector used on the dock station for iPod, iPad and

iPhone.

Available in all Apple iPod MP3 player (iPod 1G, 2G, 3G, 4G,

5G and Nano).

This connector is used on iPod (starting from 3

rd

generation),

iPad and iPhone. It is used to connect the iPod or iPhone to various

devices: PC (via USB or FireWire IEEE1394), audio amplifier, serial

device (controlled via the Apple Accessory Protocol).

3.3V Power (+)

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 at this pin slowly drains back to 0 VDC.

Firewire Power 12 VDC (+)

Different resistances indicate accessory type:

1KOhm - iPod docking station, beeps when connected

10KOhm - Takes some iPods into photo import mode

68kOhm - makes iPhone 3g send audio through line-out without

any messages

500KOhm - related to serial communication / used to enable

serial communications Used in Dension Ice Link Plus car

interface

1MOhm - Belkin auto adaptor, iPod shuts down automatically

when power disconnected Connecting pin 21 to ground with a

1MOhm resistor does stop the ipod when power (i.e.

Firewire-12V) is cut. Looks to be that when this pin is grounded

it closes a switch so that on loss of power the Ipod shuts off.

Dock has the same Resistor.

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.
