| 18 | 3.3V | 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. | 
| 19 | +12V | Firewire Power 12 VDC (+) | 
| 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 |
