| 20 | +12V | | | Power for connector (3.3 V 500 mA) |
| 21 | Accessory Indicator/Serial ena | | | Different resistances indicate accessory type: 1KOhm - iPod docking station, beeps when connected .. 10KOhm - Takes some iPods into photo import mode....500KOhm - related to serial communication / used to enable serial |
| 22 | TPA (-) | | | FireWire Data TPA (-) |
| 23 | 5 VDC (+) | | | USB Power 5 VDC (+) |
| 24 | TPA (+) | | | FireWire Data TPA (+) |
| 25 | Data (-) | | | USB Data (-) |
| 26 | TPB (-) | | | FireWire Data TPB (-) |
| 27 | Data (+) | | | USB Data (+) 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 |
