Sorry guys, but i am in trouble to use the ipaq connector of heicom mouse GPS to connect the GPS to XDA. I have modified the pinout connections of previous Ipaq connector according to XDA connections. I have not found a connection for the pin 6 on ipaq connector. Please help me to find the right pinout connections to use heicom with xda.
I have translated the power connections to pins 20,21,22. Then i have moved the other two pins to the right location on xda side, but the xda tell me that there is not a com1 port.If i try to use com2 port it doesn't work.The doubt is: i can't find a connection for pin 6 on xda side. Can anyone help me ?

Hi !
Try to turn off the IR port on XDA and will be work !
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!
Hi, hope someone can check.
Is it supposed to be a "block" or separator between the pins in the USB contact on the tytn2 ? or is it just "stand alone" out from the device ?
like
pin 1-4
separator/block
pin 5-11
?
pinout
I think this might help:

i found out, someone sendt me a picture from the usb contact.
seems i'm missing a plastic "block"/"separator" in the center of the contact.
I only have the pins sticking out from the device.
i've seen a DIY guide to change here on XDA, just need to find it again
I think it would be fun to try to interface some external hardware to the NC. A serial port would make this much easier.
Has anyone discovered any serial lines on the PCB? I've searched quite a bit on the forum and not found anything. Perhaps some of the GSM or 802.11 module lines are connected to a UART?
Thanks,
DC
Hi all,
I have started the long process to "hopefully" de-brick my G1. I have a question though, I have the HTC ExtUSB-3.5mm converter, so I know I can use it for the serial cable, the problem is I don't know which wire connects to which pin, could someone possibly help me with that ?
Fwiw, here's a low-res photo of my cable : (Can't put outside link since this is my first post)

I can provide a higher-res version later if needed, I just don't have the good camera right now.
OK, I was able to identify the wires by breaking the 3.5mm jack open. There's a small labeled board inside. I'll post pictures soon when I have the camera.
