Hi All,
I had reviewed the XDA connector wiring diagram, and confused about all the ground pins on sx56. I had order a standard stock serial cable from GOMATIC and it didn't work. Took it apart and rewired to the follow:
SX-56 pin 8 to db9 pin 3,
pin 10 to db9 pin 2
pin 2 to db9 pin 5. (gnd)
Still no go, should I be adding all the gnd pins to db 9 pin 5 gnd
( 5,16,17,18)
cheers,
edmond
Yep, you need all the ground pins shorted to device gnd.
I tryed shorting all the ground pins and my serial cable works fine for polling requirements.

I converted my orginal O2 sync lead into a serial cable (seemed a cracking idea at the time).
took the connector apart, used the existing wires, cut the wires coming from the power socket and chucked a 9 pin d type on the other end. i left tx and rx straight so it could be connected easily to the cable (which is crossed) from my friends etrex gps, all works well.
I can't remember which ground i used but i just picked the easiest to re-route a wire to, if you are just doing 3 wire rs232 then you shouldn't need to short the grounds.
Help me psl my IIi can not heard phone conversation when plug sync charger.
I have exactly the same problem.
I bought a retractable sync/charge cable from ebay.
http://stores.ebay.co.uk/PDA-Sync-and-Charge-Cables-and-Crad
However, if the cable is plugged into the phone, then the phone speaker (and I think also the mic) are muted. The cable dosn't even have to be plugged into the PC USB port to cause this problem.
At first I thought this was some incorrect wiring on pin 19 of the connector at the XDA end of the cable. This signal is meant to control whether the sound is driven out of the car kit pins or not. However, this signal was not connected on the connector, which should be ok.
I noticed that if the phone is paced in the original sync cradle, then the pda appears to go into handsfree mode, which would tally with one of the functions of pin 19.
All I can guess is that the s/w in the phone detects a signal on the USB pins and attempts to route sound out via the car kit pins.
Anybody know of a fix for this?
Cheers,
Chris.
I know many people have exactly this problem. It is not a problem of our XDAIIi, it is the problem of the Sync charger. I remember someone has shown how to fix this problem of the sync charger in a Vietnamese mobile phone forum but I don't understand anything 'bout electric so I can not translate it. What a pity!
Hi MrSandman,
I dont speak Vietnamese, but I do know electronics.
If you could post a link to the forum, I may be able to make some sense of it.
Thanks,
Chris.
I have the link but I'm sure u will not understand anything 'cause everything is in Vietnamese. In that topic, one guy said that he could fix that f***ing problem and if anyone wanted to fix it, just brought the sync charger to him. He just shown how to fix it in a few words that no one could understand. But in general, he said: "open the plug head of the sync charger and remove the first "masse" string". Does anyone know what is the "masse string"?
Fixed !!!
This works for my cable - but try this at your own risk!!
After thinking about it some more and re-reading the connector signal descriptions here:
http://wiki.xda-developers.com/index.php?pagename=Connectors
I took another look at the wiring in my cable.
I noticed that pin2 (GND/Sense) was connected to the other GND pins at the XDA end of the cable. The notes in the above web page states this will cause the phone to hang up.
I disconnected this pin from GND and now I can hear phonecalls when the cable is plugged into the phone.
I noticed that pin 5 (Analog GND) was also connected to the other GND pins which is also apparently a bad thing. I disconnected it just in case.
Pins 20,21 and 22 are the 5v positive charge connections. They are not connected in my cable and I wondered about connecting them to the USB 5v signal. I decided to leave it in the end as they may draw too much current form the USB port. The phone does charge anyway - just very slowly.
Hope this helps.
Chris.
Mentioned fix works fine for me
Thanks!
I have the same problem also.. i've read the wiki but did'nt catch well what it saying. Please put in in a simple words step by step what to do..oo please..
2 GND / SENSE
5 ANALOG GND
16 GND
17 GND
18 GND
In my cable connector there were two small red wires soldered to 3 pins (from '2' to '5' and from '5' to all three GND pins which were soldered together as one pin;
The thing is that '2' shouldn't be connected to GND. In wiki there were suggestion not to connect '5' to GND as well (has nothing to do with sound problem).
I removed those red wires and everything is working fine (I'm using it for a month now);
Be careful and good luck!
I received a Wing from T-Mobile yesterday and the device shipped with standard USB Mini connector (for sync/power) (rectangle with flared bottom) and a wall charger with the same typical mini USB connector. However, the connector on the phone is a similar rectangle shape, but has one diagonal corner, otherwise a perfect rectangle (while also some sort of mini USB connector, this connector is capable of handling audio in addition to sync and power...) It is the same jack that the headphones/mic fit into
In order to make this work, HTC packaged a small 1x1 node with a pigtail to convert the traditional flared mini USB connector to the new format connector.
Does anyone know where such a part might be able to be purchased? Or what the "name" of the connector is that I am describing? T-Mobile and HTC have both been rather useless and arrogant about the subject.
Thanks,

http://www.hot-wire-telekom.de/index.php?aktion=detail&suche=HTC TyTN&asuche=HW132471 - an audioadapter
http://www.hot-wire-telekom.de/index.php?aktion=detail&suche=HTC TyTN&asuche=HW132233
Don´t know exactly what you mean? I´m using several USB cables and they all work.
If you want an adapter to use two usb (charge AND headset) HTC himselfe has one. And if you want an usb --> 2,5mm there are several on ebay.
FYI ... the new HTC USB connector is actually a standard Mini-USB with extra pins for analog audio. If you were to take your standard USB cable and plus it into the phone, it should work. The only thing you need the adapter for is to use the headset, which is unfortunate. All the adapter does is split off the USB signal from the audio signal.
At least, this is how I understand it. My Wing won't be here until Tuesday.
In the USA, the Wing ships with a 2-way splitter. One plug is for USB POWER, and the other for headset. Err... I don't know which, if either, DATA would go over, it's mainly intended for use in the car when you want to have it plugged in but use the headset also!
I need to order a smaller audio-converter... something that can go inline with my headphones without looking/feeling/being stupid-big.

I ordered a converted from usb to 2.5mm from igonemobile for use on my Dash and my Wing. It's about 4 inches long, not too big in my opinion.
So far so good. 10 bucks, shipping included.

I see there was excellent work done by others to determine pinout for Nook Color/Tablet connector.
Now it would be great if we can get somebody to do the same for Nook HDs.
Additionally I really-really need a serial port out of the new Nooks for my kernel experiments (hopefully there's a serial in the big connector, but even if not, and somebody can help me to just solder wires somewhere on the pcb to gain serial, that would be great).
Please hit your hardware techie friends for me if you have any
If there is a serious person interested in this with no Nook to play, please contact me and I'll arrange for something.
(I already researched the Nook Color way of getting serial via twl on usb connector, but the newer twl in the newer Nooks does not have this car kit mode).

I'm surprised no one has done this yet. I read somewhere that b&n simply modified an iPod connector and often times I've found that means they simply changed the order of the wires in order to gain propriety and therefore extra revenue. I have Two hd+ sitting on my desk with no charge because I'm too cheap to pay 30 bucks for a cable from b&n. I also have one charging cable cut in half so maybe I'll get on this myself, not that I can really take on another project at the moment.
The standard USB cable that came with the Nook only has 4 pins inside (going to the nook), so even if you cut your cable I don't think you will find anything useful.
I'm not sure about the HDMI one, it should have some extra pins inside to enable the video output, but I think that, without finding a compatible male plug with all the pins intact, it will be quite hard to find out the purpose of each pin.
Someone brave can do it on the nook side but I haven't open mine yet
Linux can use usb serial as console.
But I don't know is it possible to switch Nook usb subsystem to usb host early at boot.

No, and by the time usb is up it's way too late in the booting game.
The big benefit of a real serial out is you get the output from bootloader and then transitioning into kernel including very early booting.
The nook end of the cable has only six pins. Two top and bottom on one side and one top and bottom on the other side. It would be easy to see what they connect to on the USB side. I'm definitely not an electronics engineer so I'm wondering if that is what is being discussed here and how that would do us any good? I would like to diy a car charger if I can.
pinout
I opened my Nook HD+, and there is a test point near the dock connector labeled usb-id. If this TP is shorted to GND with a slave USB device attached thru a USB-A to A gender bender, the Nook acts as host as expected per USB-OTG standard. This TP maps to pin 24. Unfortunately, this isn't one of the pins to a Nook HD+ USB cable.
The Nook HD+'s motherboard is labeled EXCELLENTLY. I've gotten most of the pins I can get easily. I think the remaining pins are for HDMI (which makes sense seeing B&N makes an HDMI adapter cable...). The HDMI adapter cable will probably get the remaining pins.
Here's the pinout I've got so far:

Also, there are two test points, SDA2-TX and SCL2-RX. These are I2C test points but I can't tell if they are the HDMI side or the system side. The HDMI chip is the TI TPD12s015, datasheet can be googled. Just a hunch that these are the HDMI side, since the datasheet says SDA_B and SCL_B are HDMI side, and they're labeled as SDA2 and SCL2.
connector type
Also, the Nook HD+ connector is NOT the same design as an Apple Dock Connector. The Apple connector has all the pins on one side of the internal fitting, while the Nook's connector has the pins on both sides.
So anyone attempting to mod their own connector should use a Nook connector.
Crud, i just bought one of those Samsung 30 pin to micro SD adapters hoping I could pull it apart and mod it, maybe I can't after all.
#edit# Is this our connector?
http://en.m.wikipedia.org/wiki/PDMI
Nope, not a PDMI...

No, from what I can tell, a PDMI connector is very similar to a Apple Dock Connector, with different pinouts assigned. The Nook HD+ has a unique connector layout from what I can tell.
It's similar to this:
...1...3...5...
...|...|...|...|...|...|...|...|...|...|...|...|..|...|...|
.+-v---v---v---v---v---v---v---v---v---v---v---v---v---v---v---+

.....|...|...|...|...|...|...|...|...|...|...|...|..|...|...|
.....2...4...6...
The Apple and Samsung have all pins on one side only, at double the density.

the TX one is the serial out, I got Adam Outler here at ABBQ to solder into it and I got the console out. Sadly it's not mapped anywhere in the connector, but at least I got my serial out now. We are less sure about the RX one, but I'll try it out once I get back home on Sunday.
Big thanks to Adam too!

This is just a guess, but would not TX = transmit & RX = Recieve ?

Yes.
So TX definitely transmits the console output, we see it.
But tryign to input stuff onto RX pin does not result in anything visible, so that's why we are less sure if that's the input into the serial console.
But even if not, the console output is the more important one anyway for my kernel debugging plans.
Host Mode?
Does this imply that using the app to change USB to host mode will not work? I have seen several articles on using app with gender changer to get external keyboard or storage to HD+
I opened my Nook HD+, too. And I took some photos.

Sorry, new user prevented from posting outside links in their messages.
Now I wonder if 5 test points of USB VBUS (+5VDC)、USB D-、USB D+、GND and USB-ID are connected to a MicroUSB Female adapter (5 pin) like most of Android smartphones and pads, will a MHL MicroUSB to HDMI cable work with the Nook HD+ ?
Has anyone ever opened up the HDMI adapter?
I would like to see whats inside before I rip mine open.

As you can see, there is full HDMI signals set, so adaptor is just pass-through connection, no external chip needed in adaptor.
Regarding RX, it goes through TI TPD12s015. The PCB pad sits on chip output (system side), which is open-drain and can suppress this signal when HDMI 5V is not activated (reflecting connector's side not powered from HDMI 5V pullup). To activate it TPD12s015 input LS_OE and CT_CP_HPD must be set high (OMAP GPIOs) - VDAC-HDMI pad near processor?
But maybe CONS_2700_UART1 connector near processor will be more suitable for console?

Yes, that.
Have you done any ripping? I don't really have a use for the HDMI cable, but would buy and rip if I could get my mitts on the line level outputs. Can't imagine they'd plumb those, but I can dream.
Here is photos of my hdmi adapter(remove spaces from urls):

It is not so simple as i thought.
This is all very interesting, and some nice pics. I wonder, has anyone attempted (or even considered) to replace the annoying proprietary connector by soldering a replacement micro-USB onto the PCB? Is it even viable?
I can't understand why they would be so daft as to introduce a non-standard connection. Apple can just about get away with it because, well, they're Apple.
