Several people have asked my questions regarding the connector on that adapter that comes with the XDA II and allows you to use the AC/DC charger without the cradle. :idea:
THis info is quite usefull, also if you are building your own usb sync/charge cable.
First off, the AC/DC charger is rated at 5V and 1 amp, though it has a no-lead voltage around 6.3V (GND is on the outside of the charger plug, +5 Volts on the inside hole/pin). You don't really need the 1 amp to charge the XDA, it's just there so that you can also charge the second battery, which you can insert into the cradle .
Now for the Pinout on the adapter. See here for more info on the XDA connector: http://www.xda-developers.com/connectors/
Pin 20,21,22: +5 Volt
Pin 16,17,18: GND
Pin 5: GND
Shorting the lines across three pins provides current load leveling for charging.
Now for the usb sync/charge cable. Here we need to add the following pins:
Pin 2: GND (my usb charge/sync cable does not connect to pin 5, just pin 2, so these are probably shorted inside the XDA)
Pin 13: +5 Volt
Pin 14: USB Data H(+)
Pin 15: USB Data L (-)
From the design, it becomes evident that the pins 16-18/20-22 are only used for the charge circuitry. There is probably a current sensing circuit in this set.
Pins 2 and 5 are the digital ground. Pin 13 powers the usb circuitry, also waking the XDA and starting AxctiveSync.
BTW: The PDA will only charge if at least one of the pins 16,17,or 18 isconnected to ground and at least one of the pins 20,21 or 22 are connected to +5V. Otherwise, though the XDA may say it is charging, it will actually just drain the battery.

I just received my iMate XDA2. I have a charging connector/USB cable combo left over from my XDA1. I inserted it into the XDA2 and the amber glowed (charging) and got to green (charged). Your comment about if pins aren't grounded, unit appears to be charging but actually isn't. Is there a way to confirm the charge/USB combo is actually okay for my XDA2?
from what ive heard/been reading the XDA 2 charger kicks out 2Amp max not 1A
and cahrging via usb will drain your battery more then it will charge it?
so i dont think modding the cradel to charge via usb will do nothing but drain your xda2 whilst sitting on it as it will be lit up and activesync will be open

The charger is rated actually at 1 amp and for purposes of charging the 2nd battery in the cradle if one had a spare. Thus 500mA or less will charge the unit. It did mine.
oh how come on xpansys their chargers kick out 2A :? :shock:
Just for those without an electrical engineering degree:
Important for charging is the voltage, not the current. Sure, a large charge current could charge the battery faster, but even then only if the charge voltage were high enough. And then, these batteries are highly sensitive beasts, requiring a complex charge strategy - if the current is too high they just blow up! If the current is low, it just takes longer.
The MDA/XDA has an intelligent charge circuit, which is software controlled and most likely senses and controls the actual charge current. When doing a "full blow" charge it probably limits the current to around 0.5 amps (though I haven't measured this), but will decrease this current considerably once the battery gets nearly full (otherwise we would cook the battery).
Aes, you can charge the XDA without problems from the usb bus. The only caveat: check that cable -see above!. I do it all the time and in fact, have often gone into internet cafe's whilst on the road just to charge my XDA (cause the charger was defect).
And yes, you can see if the battery is really charging: if the light is on and the %-age full increases over a few minutes, then the battery is really charging.
ah cool cheers for clearing that up then lol so it does work my bad :\ just thought it was weird how their cahrgers are 2A meaning it will be charged in like 2 seconds like :\ thats what confused me

The rated output is 5V / 2A for the XDA2 AC adapter. My math was a little in error. If you don't have a 2nd battery charging in the cradle, than a 5V / 1A charger would suffice. Howver, it did a great job of charging just thru the USB cable. I can't remember off the top of my head what a USB line is capable of - 500mA??
Sorry for the confusion.
i've got the solution!!!
Hi everyone, i think i have the solution of XDA II not charging on USB port using XDA sync/charger cable... if u want the XDA II charging from USB, just open up the connector and disconnect the 20,21,22 pins from USB bus power line. After that, u can use XDA sync/charge cable in any USB port and they will sync and charge the XDA II.
How i know this??? 'cos i "reverse-engineered" the connection of the cradle... i was wondered y using the same usb port, the cradle can charge while the sync cable can't... so i test all the connection of the cradle and found that pin 20,21,22 and also pin 2 is disconnect. The pin 20,21,22 only connected to power when u plug in the DC into the cradle. This mean that pin 20,21,22 connected to DC (+) while the pin 2 is connected to DC (-) only when u plug in the external DC supply to the cradle.
I've modified my XDA sync cable and now i can charge my XDA II on any USB port even from my laptop. Hope this helps for those who purchased the XDA sync/charge cable to use with XDA II. :wink:
To those who like to go further....
The only problem that i can c now is that if u modified the cable and u use it with a car adaptor, will it charge the XDA II as fast as possible like when u plug in the external DC supply? OR will it only trickle charge the XDA II as using USB port? i really don't know 'cos i don't have a car here with me to try it out... but i think it will only trickle charge the XDA II only...
Therefore, to those who like to get charge faster in the car, u can install a small switch connected between the USB power line and pin 20,21,22. By switching the switch, u can choose between trickle charge and fast charge. 8)

I would be most carefull about this solution. I know that the charge-light will go on, but I'm not sure it will actually charge the battery (just check after 5-10 minutes if the batteries have really charged.
As you noted, the external charger goes across pins 20-22 (+5V) and 16-18(GND). This is where the XDA is meant to charge the battery - and it will do so under any conditions if the +5V is applied here. Pin 13 is meant to power the usb circuitry and it wakes the XDA II up, starting ActiveSync at the same time, it is not meant to charge the battery.
Hi, i've checked and tried on few machines... it really works... trust me... maybe the charging circuit on XDA II is different from XDA???
And as i said in the post b4, the connection is "copied" from the original cradle, so it's absolutely correct unless i did something wrong on my side... but well i've double checked it... :wink:
If u've some time to spare, can u pls check the connection of the cradle as well? it's good to verify so that all XDA II users will benefit from this... Thanks!
Should work, since I only use the cradle without power supply to charge my MDA II. Full or empty doesn't matter, the MDA II always gets fully charged.
Didn't measure the pin layout yet in my cradle.
Upgrading from T-mobile pocket pc phone edition to imate
In reveiewing this thread - it appears that I will be able to use my car charging cradle, and my USB chrger/synch cable, perhaps with some minor pin adjustments.
I would like to know if anyone has experienced any damage/ problems relating to using xda1 accessories with the xda2.
Also, I have the thumb-keyboard, and wonder if anyone has tried using the xda1 thumbboard with the xda2. Would like to avoid re-buying all my accessories if possible. Help is appreciated.

Just to check with you, i am going to test my car charger....are you saying that the +ve needs to be connected to either one of the pins (#20,21,22) and -ve to gnd pins (16,17,18).
Is all the gnd #2,#5, #16, #17 & #18 shorted? and pin#20, 21 and 22 shorted as well?
Thanks. :?:
Hi i've made a "not-so-nice" layout... which i think explained better than myself... :lol:
The lower part showed the connection needs to sync and charge with USB only. The upper part become valid when u plug in the external DC into the cradle. I do think that pins 2,5 is somehow shorted internally.
So, if u test ur car charger, i think pins 20,21,22 should shorted with pin 13 to the power(+) while pins 2,5,16,17,18 are shorted to ground(-).
The XDA car charger shouldn't be a problem to charge the XDA II... it's just the XDA USB sync and charge cable that causing the non-charge bug on XDA II...
Hope this clear all the confusion... :wink:

Hi all,
I'm sure this will infuriate those guys who are trying their best to explain this to us thickies....but.....
I have purchased the L'il Sync cable from eXpansys (from PPCTech I think) and, obviously, it won't charge the XDA-II.
Now I have a soldering iron, and I'm prepared to use it, but I need to know EXACTLY which wires to chop, or where to solder. I'm still having trouble woking out whether to solder pin 16,17 or 18 to somewhere - or whether to cut other wires off. I fact - I don't really know which pin is which!
I know you guys have the know-how - but you need to make it really simple for me to understand!
Please help!!
Thanks,

Ok, i've flashed the 2.3.4. I the next days will try the behaviours.
Any news? have you tried?
The battery charging so slow. It may take more then 4 hour for full charging. Can this problem solved after flash to 2.3.4?
With the new rom 2.3.4 flashed, the battery consume seems to be much linear than before, moreover maybe i've find the solution in the usb cable used in the car: a quick test by using the original usb cable with gps and data connection active has incremented the battery charge by 1% in a 10 km path.
Maybe the original cable has some special terminals configuration?
More extensive tests in next days.
Any improvement of charging time required after flash with 2.3.4 rom?

I know this problem from my HTC Desire, it's was the same and the reason was that a orig. charching cable from HTC had a special pin which says the phone to charge like ac with full power and not only usb power! You can check this in the menü. There is an entry for charching which says "AC" or "USB" charching. If it shows "USB" it goes very slow! But i don't know that there is a special charching cable for car charching from samsung available too.
Where is the menu entry that shows if is charging USB or AC?
Thanks
Hi,
You will find it there:
Settings -> (telephone) Status -> Battery Status
There it says charging AC or USB
With AC it charges with full power, with USB it charges with 500mAh only -- which is not enough power for GPS and Screen on.
(At least it's like that with HTC devices)
I have a HTC Legend -- my solution to this problem was to short-circuit the Data pins in the Micro-USB-Port of the Car-Charger.
The Original HTC-AC->USB Adapter also has the Data-Pins Short circuited.
If you buy the HTC Car-charger you will geht a special USB-Cable that only works for Charging and not for Data transfer.
So HTC Devices recognize the Original charges by detecting the short-circuited Data pins.
I don't know if it's the same with Samsung devices!
I hope it helped you a bit!
Any link on how to connect the circuited Data pins?
Yes, probably a connection scheme would be useful.
I bought today a car adapter with 1000 mah Power and micro usb port. It charges with "AC" shown in the system
It was very cheap only 10,- EUR from Germany Company "Hama" a great hardware
Yesterday i've tried with another cheap charger, and AC charge is here, by using the same cable of 2100 mAh charger.
So my conclusion is that the trick is in the charger port, not in the cable.
By searching on google, seems that the two central pins need to be short-circuited...
Hello everyone, I hope my English is understandable.
To avoid damaging the cable, I have modded the charger.
Generally the chargers are very simple to dismount: simply unscrew the ring that holds the spring and the fuse and remove a couple of screws.
Usually the data pins are soldered on the circuit board only for mechanical reasons (increase the endurance of the connector), but they are connected to nothing. Short-circuit the data pins with a solder, directly on the circuit board.
Now i see AC charge.
My old Toshiba TG01 required the same trick.

You can make it with extension cable, a resistor (50 K ohm min , 150 K ohm max) and PVC insulating tape. Cut the extension cable so you will have 2 ends with 4 wires.
red as Vcc+ 5V
white and green as D+ and D- (data)
and black as ground.
Lets assume that the big USB plug you gonna plug on the charger, is the input to our modification, and the wire with the female plug is the output of our modification.
We don't need the green and white data wires that coming from the input, since those are the "USB" signals. We need only the 5V voltage which is the red and black, so we must insulate with tape white and green. Don't strip them, just insulate.
On the output cable with the female USB plug we still have 4 wires and we gonna connect the ground directly with the input ground. Strip the ends, twist together and insulate with tape.
Then connect the red wires (input and output) and the resistor one end ALL Together and insulate with tape. (3 points as one - red, red, resistor)
Strip wires, twist together with resistor's one end and insulate. Leave resistors other end free for later.
Then strip and connect the output signal wires together (the green and white you have available) with the resistors free end. (3 points as one, white, green, resistor's 2nd end). Strip wires, twist all together, Insulate with tape and you are ready. You can insulate the resistor with tape and all the wires together so it will be nice looking. Try to make it straight and not too thick.
If you have the battery widget application by ELVISON installed you will see that your device has switched to AC mode.
Also, this is going to work as AC on a usb port of a PC. Good luck!
Going on the above post you could use a micro extension cable and just create a short six inch extension that can be used on any usb cable.
Why would one do this?
The microUSB charging spec requires a dedicated charging port to have two of the pins shorted together so that the phone can detect that it isn't a USB port/hub on the other end. A USB port can only supply 500 mA whereas a charging port (one that isn't trying to pass data and has the two wires shorted) can supply 1000 mA.
Many "cheap" (and a lot of "expensive") car adapters don't have the pins shorted so the phone thinks there is a live USB port on the other end and "protects" it by drawing under 500 mA from it. As a result, they only charge the phone "half as fast" as they could (assuming they could put out the full "1 A" = 1000 mA, check the label).
The "fix" is to short the pins together, either in the charger itself, or in the connecting cable.
The "fast charge mode" some kernels and ROMs supply basically tells charger in the phone, "Ignore what the cable is telling you, just turn off USB data and pull 1000 mA." Hence the warnings that you may permanently damage your computer or charger.

Experimentation and Conclusions:-
1. Touch screen works fine when it is connected to a wall charger that has earthing port and output less than or equal to 850mA.
2. Touch screen works fine when it is connected to a wall charger that has output of 580mA as in case of moto G charger.... In this case it is not required for the charger to be a 3-pin charger or a charger having a earthing port....
Don't buy a charger which doesn't qualify above criteria!!!
3. When connected to laptop using data cable the touch screen will work fine if you are not charging the laptop. The ouput current in this case is 500mA.
4. When the laptop is charging and you connect the phone, touch screen will not again behave properly. I don't know the reason in this case but somehow the USB current output changes...

I am charging with non-genuine 2 pin (EU plug , Eastern Europe location) charger which is even non branded, 2USB ports with markings for "iPad/iPhone", "for Sams" with non genuine flat cable - there is no problem with touchscreen. Also used genuine cable and 1A adapter (both original) from my HTC Desire - 2 pins, no grounding, no problems.
Tried once original adapter (2pin) + original cable and they are working without messing touch screen too.
When phone is connected to PC which HAS grounding - there is not a problem with non genuine cable from adapter 1, and with original one from HTC. For me it looks like grounding is making this mess. You can either put an insulation tape on grounding pin and try again or try to insulate metal part of USB-A connector of cable. Of course you can try to buy cheap microusb cable which will have no grounding .
