Does anybody has the HTC RC E240 pinout? - General Accessories

I've got HTC RC E240 Headset. Suddenly the buttons stopped working. I've opened the remote just to find that it has 4 contacts but there were 5 colored wires. There was no place for the green wire.
Here's the scheme of what I have found after opening the remote. The numbers represent the wires and where they pop up on the jack. It looks like wires 6 and 7 are not connected to the jack at all. Need help for assembling this accessory again.

How to add RS-232 and audio out to a USB XDAII cradle

Out of curiosity last yesterday, I opened the cradle to see whats in it
I worked out with my trusty multimeter how to add an RS-232 (full) to it
On the pic with the CON1 connector starting from the D6 diode (reversed in picture) on Pic1
Cradle Pin---XDA pin
1-------------16,17,18, GND
2-------------6 DCD
3-------------7 CTS
4-------------8 TXD Main Tx point for eg GPS
5-------------9 RTS
6-------------16,17,18, GND
7-------------10 RXD Main Rx point for eg GPS
8-------------11 DTR
9-------------16,17,18 GND
10------------unknown
11------------unknown
12------------unknown
13------------unknown
14------------unknown
To add audio out to your cradle find on the CON2 beside the DC in connection of pic 4
Audio L is on the 10 o'clock side of the connector (from the picture) and Audio R is on the 2 o'clock side
Here are two larger pictures attached
The mic input is harder. The PCB's have a lot of points for further components to be used, my guess is for the XDA2 car kit audio control, as on the PCB / cradle there is a hole for a microphone, just look at your cradle now, those 3 tiny holes! Also look at the back of the cradle, there are 3 connections, DC in, USB, and a piece of rubber. This is where a headphone connector SHOULD be (cheap bas~%rds)
But if you are determined to put a mic in it (pin1 on XDA) can be found on the PCB with the 22pin connection. On the side with the LED's find TP47 , its one of the nearest points to the 22 pin connection.
And a final note these finding are not guaranteed to work, I have not tested this yet, so test fully yourself before you use this info. This info is a guideline only !
I believe that the cradle should have come with a headphone socket and a microphone built in!!
Look at :
http://www.myxda.com/XdaII/happenings/template/XdaIIAccessories.vm
Have we been short changed?? Are we eligable for and upgrade of the cradle??
It only seems to mention the mic/audio on the one they are selling seperately.
Anyone tried the audio mod till now (before goin out to buy a torx key)?

XDA2 2,5'' jack PINout !

I didn't find here the pinout description of 2,5mm jack connector from XDA2.
There is stereo out, microphone in and two buttons.
I tried to buy 2,5mm connector, but it is not usable - connector itself fits to the XDA2, but the connector's body is too thick so the connector can not be fully plugged in.
So i bought some Nokia portable handsfree, which is also equipped with 2,5mm jack with four pins. So all i need is to know, how it should be connected.
I also bought a small plastic box, two 3,5mm stereo females and two little buttons. All of those things will be installed into that tiny box (plus the Nokia 2,5mm male connector). So this will work as an universal adaptor: from XDA2 to anything. I already bought big HiFi earphones with built-in microphone - it has two male 3,5mm jacks - one for stereosound, second for the microphone - so I'll be able to connect it to the XDA2 using my homemade tiny box and HiFi telephoning will become the reality ;-))
I'd also like to make a "homemade" simple car handsfree : I'll connect XDA's audio out to AudioIn on my car audio (also suitable for playing MP3 from XDA on car audio system). And I'll connect a standalone external microphone to XDA, microphone will be placed somewhere in the cabine.
Does it sound insane? Or realistic? Does anybody know the XDA2 jack pinout?
http://xda-developers.com/connectors/
this is xda1 but they are suppose to be able to use the same headphones
so it would help a bit
even though the xda1 dont support the 2 button thingy
Hey, as I trashed my cable I had to find out a little bit about the connecter
I write this from memory, so please handle with care ;-) :
from top to bottom
top ring - stereo out (left or right)
next ring - stereo out (right or left)
next - microphone in
next - ground
metallic ring in the inside of the connector - phone switch
By the way.. these pins are protect versus each other.. you'll have some tries..
Alex
The truth is that I can use the system connector instead of the 2,5mm jack.
AudioOut and MicrophoneIn pins are on the system connector as well...
So meybe I'll make SystemConnector-to-3,5mmJack adaptor ;-)
Or is there a difference?
Ehm..I had simply buyed a 2,5 to 3,5 Jack and cut a piece of it to fit into phone:

Well, OK. But it is only a stereo out, you don't have a microphone in. I'd like both of them plus those two buttons (red and green phone button)...

this one have the mic but dont support the pickup and slam down of the phone

well if you wanted to connect something else to the sysconnector you would not be able to connect something like charger or GPS
then imho it would make more sence using the 2.5 connection which cant be used for anything but sound anyway
Well, I am looking for such a device, but then one that will work with the XDA2/MDA2
Because I would like to use my own B&O headset, but would like to keep the phone function with microphone and answer buttons
So if somebody would like to spend an hour on the web for a detailed surch :wink:
make it your self...
takes less than 30 minutes (if you know how to use a solder iron)
I did it and I am trulty happy with it.
Alex
but is it not a problem that the lengh of the 3.5mm headset get added to the length of the wire from the device to the buttons and mic
i mean the mic need to be able to reach ones mough but the lenght from ones mouth to ones ears are not that long and with the added 3.5 mm headset lenght it would seme to become a wire mess?
Yes and No...
Yes if you do nothing.
No if you wrap it up a little.
well if you wrap the wire you will create a coil line effect
and that damage audio quality
just kidding i'm not a real audiophile
It seems that info in xda-developers.com/connectors/ is aplicable to XDA I.
XDAII headset has 2 buttons, answer and finish.
I'm specially interested in the 22pin pinout, that I've told IS DIFFERENT from the XDA I.
Can anybody point me with updated info on XDA II conneectors?
Thanks
vcp
xant give the wiring of the 2.5mm on the xda2 in this thread
about the 22pin connector then

Alex,
This is correct. The XDA II uses 5 pins instead of four. The switches are both connected to the 5th ring on the inside.
Until now, I wasn't able to find this connector.
Seems it's only used on the XDA II.
The diagram of the XDA I connector is correct, only the button isn't connected over the microphone to ground. So if you only need audio and mike, use that schematic.

Blue Angel audio connector?

Hi,
I want to connect an external speaker and microphone to my Qtek9090. I thought the easiest way to do it is to simply cut the headset wire, plug the 2.5mm connector in and connect my speaker and mic to those wires. I have taken apart the headset that comes with it and there's the following wires in it:
wire1:
- blue
- copper(1)
- red
- red/green
wire2:
- white
- copper(2)
From taking apart the volume slider I think blue and copper(1) are the wires for the audio (L&R). But I'm not sure. I can't figure out what the mic and ground wires are :?
Does anyone know more? Anyone tried looking at this?
Grtz,
DUTCH
just feed a low level audio signal to the wires. You should distinguish left and right. The remaining one must be the mic....
or...
buy an adapter. Both expansys and proporta.com sell adapters.
Nigel
I've been searching for those adapters and found many. The only problem is: none of them have a microphone connector :? .
Now I might have an option here, but i'm not sure this one suits the Qtek9090 (Blue Angel) I have: if I use this one. I could connect my speakers to the stereo 3.5mm headphone jack and my microphone to the mono 3.5mm headset jack.
The only thing is: what part of the headset connector is the microphone? The tip?
Grtz,
DUTCH

Therefore no adapter or headset made for the Himalaya will work with the Blue Angle.
Do you know if it's compatible with nokia headset ?
like this one :
Nokia HDD1 : http://www.nokia.com/cda13/0,5184,733,00.html

No, I've tried with a Nokia wired headset and it didn't work at all.
I ordered the audio connector mentioned (this one).
When recording a note for example everything works just fine, BUT when in 'phone mode' (making a phone call) it doesn't work.
Anyone got a clue/solution for this? Or should I start thinking about making this work via the 22-pin connector?
Grtz,
DUTCH
9090 should support audio from the bottom connector. I assume you want to use it in your car. If you want to connect a external speaker you should amplify the signal. There is a DIY carkit on http://wiki.xda-developers.com/wiki/Connectors . Maybe this could be handy. Also my phone supplier told me that in about a week there will be a complete carkit WITH decent Carcomm cradle and GPS connection (all wired so no BT connections needed). I will buy this when it is released so will keep you guys updated.
if I use this one. I could connect my speakers to the stereo 3.5mm headphone jack and my microphone to the mono 3.5mm headset jack.

I purchased this one for my old TMobile xda I and the Blue Angel.
Both are headphone jacks and niether cna be used for a mic. There is a built in mic and mute button (that you have to hold)

Here's the headset pinout + Where's tha audio in the bottom?

I used to have the original XDA (T-Mobile USA). I just bought the Cingular-branded Blue Angel (btw, they come unlocked).
As many have stated, the pinout for the headset is different. Here's how it's set up in the Blue Angel:
Sleeve - Ring 1 - Ring 2 - Tip
Ground - Out R - Out L - Mic In
As opposed to the original XDA:
Sleeve - Ring 1 - Ring 2 - Tip
Ground - Mic In - Out R - Out L
Now, I really need help to find the Audio in/out pins in the bottom connector. As far as I know (I checked), pin 1 is no longer Mic In.
Also, grounding pin 19 does not turn off the internal mic and speaker.
I'm a pro journalist - In the old XDA, the Mic In in the bottom connector gave me amazing sound from a Shure Microphone (through custom made cable with a line matching transformer).
I desperately need to know where's the Mic in and Audio Ground in the bottom connector. The Mic In in the top headset connector doesn't provide clean sound.
Thanks everyone.
Hey Uspino,
I got the same problem. But i find out that the pinout for only the audio on the bottom is the same as on this page :
http://wiki.xda-developers.com/wiki/Connectors
I hope anybody can find out wich pin is the mic. This weekend i will try out, so maybe monday i have an answer.
Pin 12 builds up a voltage of 3V to 4V when you make a call.
BTW, do you have a loose 22-pins connector for the mdaIII and can you tell me where i can buy this? Now i take the connector wich is shiped with the MDA for charging. I confirm the pinout you find out for the top headset.
Thanks anyway!

HTC mini-USB to 4 pole 3.5 mm

Is there such a thing as a mini-USB to 3.5 mm 4 pole adapter that works for the HTC Touch? I want to use a 3.5 mm headset with it.
sure
expensys and most other online stores like it got them coming out their rear end
http://www.expansys.com/p.aspx?i=176772
The same one that comes with Touch Pro should work.
Thanks for your suggestions, but is there something that is a bit more compact? Something like this but with 4 poles instead of 3: http://www.amazon.com/Headset-Adapter-PPC6800-Verizon-T-Mobile/dp/B0016D9URO

I have been looking for a 3.5mm headset (not headphones, the ones with in-line mic and the extra terminal), but none of them seem to work with the mic. I have one I got for my hermes a while back that has three inputs - HTC USB, proper mini usb and a 3.5mm headphone jack. Very cool for using with desktop speakers and charging or syncing at the same time, but no use if you are trying to use a 3.5mm headset socket from a Nokia.
However, I just found one on ebay that does seem to work with 3.5mm headsets. Ordered one from the US for £9 all-in, although there are some in the UK for £15+pnp. Search for "HTC Headset Adapter" and they come up.
One comment about these: HTC has started making 10-pin mini-USBs. The bottom row of pins are still used for communicating with activesync, but the top row is now for the audio and mic. Traditional 5-pin mini-USBs do not have the top row; hence they'll only work for activesync and not audio functions.
So if you buy a 3.5mm adapter, make sure it is 10-pin and not 5!
