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. 28 TPB (+) FireWire Data TPB (+) 29,30 GND FireWire Ground (
13、-) Notes Signals with grey background may not exist on some docking stations. Apple serial devices (i.e. iTalk and remote control) communicate with iPod (3rd generation or more) using the Apple Accessory Protocol. The serial connection uses a standard 19200 baud 8N1 protocol (the speed can be increased up to 57600 but tends to become unstable).Reference URL：http:/
