iphone 4 et cable non optimise

Mon Dock JBL est un dock officiel pour les iPhone et Ipod et avec mon iPhone j'ai le message mais pas mon Ipod rien à voir avec câble officiel ou non ou pc ou pas pc....

je pige pas ton message !! c'est en rapport avec ta voiture ou juste un soucis iphone/ipod

Le sujet a dévié sur un message concernant l'iPhone...

ok alors pose plutot ta question dans la section entraide informatique etc

J'ai posé aucune question ce sont des explications faut regarder les pages précédentes.

lol pardon ! désolée j'ai vu que le dernier message

J'avais bien compris. Pas de pb.

Attention (dit-il d'un air très solennel ! ), en tant qu'ex VAR Apple, quelques explications....

Le connecteur Dock dispose de pins permettant de signaler à l'iPhone ou à l'iPod ce qu'il y a derrière. Il peut aussi y avoir des interactions entre le périphérique Apple et le bidule sur lequel il est branché.

Potentiellement, ce connecteur peut faire beaucoup de chose.

Il est possible de réaliser un câble qui ne suit pas à 100% la norme sur les signalements (si on veut que ce câble soit versatile au niveau des i-trucs connectables) sans pour autant que ce câble ne remplisse pas sa fonction normalement.
C'est dans ce cas que l'on a ces messages.

Certains câbles vendus sur le Store déclenchent aussi ce message, comme quoi...

Le message peut vous surprendre ou vous gêner, mais dans 99,9999% le câble remplira sa fonction première correctement.

Pour ceux que cela intéresse, le pinout (à une époque secret), dévoilé depuis bien longtemps...

Pin Signal Description
1 GND Ground (-), internally connected with Pin 2 on iPod motherboard
2 GND Audio & Video ground (-), internally connected with Pin 1 on iPod motherboard
3 Right Line Out - R (+) (Audio output, right channel)
4 Left Line Out - L(+) (Audio output, left channel)
5 Right In Line In - R (+)
6 Left In
Line In - L (+)
7 ?
8 Video Out Composite video output (only when slideshow active on iPod Photo) or Component Video Pb
9 S-Video Chrominance output
for iPod Color, Photo only... or Component Video Y
10 S-Video Luminance output
for iPod Color, Photo only... or Component Video Pr
11 AUDIO_SW If connected to GND the iPhone sends audio signals through pin 3-4, otherwise it uses onboard speaker.
12 Tx ipod sending line, Serial TxD
13 Rx ipod receiving line, Serial RxD
14 RSVD Reserved
15 GND Ground (-), internally connected with pin 16 on iPod motherboard
16 GND USB GND (-), internally connected with pin 15 on iPod motherboard
17 RSVD Reserved
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.
19,20 +12V Firewire Power 12 VDC (+)
21 Accessory Indicator/Serial enable
Different resistances indicate accessory type:
1kOhm - iPod docking station, beeps when connected
10kOhm - Takes some iPods into photo import mode
6.8 kΩ - Serial port mode. Pin 11-13 are TTL level. Requires MAX232 chip to convert to RS232 levels.
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.
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 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.
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 resistor to the USB Power source +5v (23). This way the USB function is still useable for normal operations and makes it easier the fit in a plug. The resistors are not to critical 2x 150k's still work.

Merci Papy Mac !

Pour ma part, iPod nano connecté sur media-in donc pas de message.
