Subject: Carkit for XDA?
From: Bart
Date: 14 Jan, 2003 21:39:40
Is there someone who uses their XDA in a carkit (like a normal
GSM carkit), so not over the xda-speaker and microphone, as this
is just not good enough for "professional" usage....
Preferably with telephone mute for the car audio, or am I
getting overoptimistic?

I´m also looking for a "Carkit" for my XDA, but I haven´t found
anything yet. My next step is making my own. Connecting sound an
microphone seems to be no problem, but untol yet I didn´t get a
hint how make automaticl muting the radio.
Anyone got an idea?
Seems there is no pin, that indicates a ring on the connector.
Maybe it´s possible to use the audio signal.....
Subject: Car kit XDA
From: Andrew Farrell

I too am developing a car kit. I have a nokia 3310 hands free
kit, I have modified it to use the XDA (The sound is exactly the
same as a nokia phone connected) .
The only problem was I had to use an external switch to divert
the calls to the car kit (and use the radio mute), but there can
be an upside. eg text messages/reminders dont mute the radio.
The wiring is very simple and the only components yu need are 2x
capactiors and a small DPDT switch!!! ([email protected])
Take a look at the XDA connector: Pin 19 CAR_ON isn't for starting the engine as it name suggests ;-), but to mute the CD/Radio.

No it isn't. It's an input pin. See the report at our connectors page:
we said:
CAR_ON# is connected to +6V on the car charger, it's not connected in the cradle. +6V makes the phone go to speaker mode immediately when picked up or dialing. When this pin is connected to ground, the internal mike and speaker are turned off, and audio input is taken from the audio input pin on the connector, for use in real car kits.

For lack of an audio mute output, one could build a schmitt-trigger and a timer to detect the presence of audio output and and mute the car radio accordingly.
Car Charger & Car On Signal
I just bougth a Car Charger for the xda, hoping that it works like you said (Phone should go to "free speaking"), but it did not.
So, i openend the connector seeing that only Pins 2, and 22 are connected.
I changed it to connect Pins 22 & 19 to the + 6V wire (in fact only 5.7 Volt)
and the Black one to Pins 15 and 17 ( it was a bit easier to solder). Its still not working.
Does it really need all the connections you said (19,21,22 to +6 V and
15,17,18 to GND) or is something else wrong?
hi guys
Well, I was a bit more hands on with that topic, I have a specialist here which said he could make everything working given the right plans, connectors etc.
Hangary is cheap in workforce but pretty impossible to get the stuff needed.
I allready posted an outcall, lets get our informations together and produce a working version for the market, I even would like to go further and implement GPS.
So?
Lets get it started and throw together all the imput etc.
Thoughts?

For those of you who have grounded pin 19 to get sound out via bottom connector, have you seen this site which sells proper car kits for the blueangel
http://www.thb.de/index.html?lang=en
Note the bit at the bottom of the MDAIII car kit about wavedev.dll, could this be the solution to all sound out via bottom connector?
could someone who has already got pin 19 wired up test this before i bastadise my cradle with wiring of XDA II
Audio out at bottom connector
Hi,
I have just finished my work.
I have grounded pin 19 via 10K resistor and then installed wavedev.dll from the site http://www.thb.de
Now it works well. Internal mic and audio are switched to pins 1 (mic) and 3,4 (audio). I have connected the MDA III via bottom connector to my motorcycle intercom and now I can hear all instructions of my navigate software as well I can telefone with my helmet on.
I had tried it before without THBs wavedev.dll and it was only possible to use the telefone function. MP3s and navigate instructions couldn't been heard.
greetings bombur
So are the pin outs the same as the XDAII? if not could you please provide the full pin out, including power and ground
Hi,
yes, the pin layout seems to be the same as XDAII, MDAII (himalaya).
I have been fooling around with this for months now... to what did you ground pin19?
Thanks,
Dutch
I groudeed it via 10 resitor to pins 16,17,18.
But without the wavedev.dll from http://www.thb-service.de/download/MDAIII/Wavedev.dll there is no chance to get audio output from mediaplayer ond so on.
regards
Cheers! I've downloaded the .dll as well. Nice finding!
Did you do anything with PIN5 (ANALOG GND)?
Thanks,
Dutch
I connected it with audio-
Pins 3 and 4 are audi+
regards
I've tryed using this wavedev.dll to see if i've got any luck sending audio (mediaplayer. tom tom etc) to my bluetooth headset but doesn't work... Just tought it could be something with routing the audio...

I have come across a thread which described a registry hack to output tomtom GPS Sounds etc to a bluetooth headset, but i cannot find it again, but this thread in another forum backs my thinking up http://www.mtekk.com.au/forums/viewtopic.php?p=24624 you should root around the google, it is only on one of three sites, this one, MoDaCo or Mtekk but i know its possible at least
Can you make me one?
I have a PPC6600 (PDA2k, XDAIIs, etc.) and I have a couple questions...
When you unhook the bottom connector from your phone, does the audio go back to the internal speaker and microphone?
Also, when the bottom connector is plugged in, what takes precedence, your bluetooth headset or the bottom connector's audio?
Last, if I paid you could you make me a cable that would have the connector that would feed to :
3.5mm Microphone Plug
3.5mm Stereo Audio Plug
Radio Mute Plug (pin 12 supposedly?)
Power?
My vehicle's radio supports RCA feeds and Radio Mutes, and I would LOVE to get this hooked up...
Lastly, is it possible to pipe out video through the connector? (Just thinking about the XDAII backpack...)
Thanks,
Ryan

Hi rleestma,
>When you unhook the bottom connector from your phone, does the audio go back to the internal speaker and microphone? <
Yes internal speeker and mic are turned on when the connector is unhooked.
>Also, when the bottom connector is plugged in, what takes precedence, your bluetooth headset or the bottom connector's audio? <
Bluetooth headset is preferred, the external speeker works but microfone is only used from bluetooth headset.
>Last, if I paid you could you make me a cable that would have the connector that would feed to :
3.5mm Microphone Plug
3.5mm Stereo Audio Plug
Radio Mute Plug (pin 12 supposedly?)
Power? <
The answer is no. I'm glad, that my connector works. But until this I had disturbed 3 connectors because of my very small experiences in soldering.
I think that every TV or radio store could help you when you tell them the pin layout and how to groud the pin 19.
>Lastly, is it possible to pipe out video through the connector? (Just thinking about the XDA II backpack...)<
I don't have any idea how video can be piped out through the connector.

Thank you... Maybe a few more quesitons?
Thanks for the info!
Perhaps a few more questions then?
Where did you find these parts?
1. XDAIII connector
2. Wire to solder in connector
Secondly, do you have some type of diagram layout and parts list for resistors, power, etc.?
I also have very little experience doing this type of thing, but this is EXACTLY what I need for my little project...
Thank you for your help in advance!

Questions on Schematic
Hey there...
when grounding the Car_ON (pin 19) through a 10k resistor, which pin did you ground it to? Was it 15, 16, or 17? The reason I ask is that it seems that incoming power ground needs to be on 15, 17, and 18, so does that mean that the CAR_ON needs to be sent to pin 16?
See what I mean here...

Thanks,
Ryan
Hi,
I bought this connector http://www.haid-services.de/pi-680482093.htm?categoryId=49 .
The Cable and the resistor I got in a tv shop.
One pole of the resitor you have to solder to pin 19 and the other pole must be soldered to pin 16, 17 and 18.
Don't use pin 15 for ground from the car charger. It's only used for USB cable.
regards
Yes, I saw that you soldered pin 19 to pins 16, 17, and 18, but the problem is that the positive lead ties into 19, 21, and 22...
So, with that being said, i have two questions... Did you tie power into your setup? If so, then...
1. Do I tie in the positive lead from the car charger into pin 19 at all because it's going to be grounded out?
2. Do I tie in the negative lead from the car charger into all the pins, or only the ones that aren't being tied back into 19?
If you have an example that you used the worked that would be STUPENDOUS... I feel like I just need to have this quesiton answered and I'll be good to go...
Ryan
Can I use this connector, or do I need to use the other one from you?
http://store.yahoo.com/gomadic-new/ipconplug38s.html
Again, if you used power, can you let me know what pins you tied into the positive and negative? maybe a diagram?
Ry
Hi rleestma,
have a look at http://wiki.xda-developers.com/wiki/Connectors
There you can see that pins 20,21,22 are power+ and pins 16,17,18 are ground. Now connect now solder a 10k resitor between pin 19 and (16,17,18) and it should work.
But only if you download the wavedev.dll from www.thb.de
regards
wiring question
last question...
when you were wiring yours up, did you jump 19 right at the connector or did you run everything back to the opposite end of the cable and then run the 10k resistor?
Also, did you tie in the car charger's negative and all the negative pins together at the other end of the cable, or did you run one negative wire to the connector and then split it there? same for the positive...
thanks!
ryan
Hi,
the resistant fits in the connector, so there is no need to use an extra wire to connect it outside to the ground.
I connected the the pins together with solder in the connector.

hi guys here is a way to fix ur converter.
1. open ur Converter from 3.5mm side.
2. desloder all wires coming from 2.5mm side.
3. take a multimeter or continuity tester.
4. if multi meter, put it on diode testing mode.
5. hold one wire at a time and test it via multimeter(by connceting one end of mutimeter at 2.5mm connector and one end at wire)
6. note the colour and the corresponding connection on 2.5mm jack(where the multimeter beeps and confirm the continuity).
7. Do this for all 4 wires.
8. now u know that which wire is connected from which ponit(connection) of 2.5mm jack.
9. out of 4 wires 2 are for stereo sound, one is common and another one is for mic.
10. Here on my BA the wiring pattern for 2.5mm is 1st is mic, second is spkr, third is spkr, and fourth is common.(starting from silver/golden side see screen shot) as u hv noted the color and conncetion at jack.now u can identify which colour wire on ur 2.5mm jack respond to mic, spkrs and common.
11. Now on ur 3.5 mm jack side u have a mic a button and 3.5mm jack.
12. Button is for attending calls it has 4 conneting points.
13. connect the mic with 2 connecting points points of button (at similer side).
14. connect the another 2 points of button one with common wire(of 2.5mm) and and another with mic wire of 2.5mm. (step 8 helps u here)
15. Now on 3.5 mm jack u have three connections one for left channel, second for right channel and one is common for both.u can identify the common easily as in all 3.5 mm jack the last and larger conection is always for common.
16. connect either left or right connection of 3.5 mm jack with one of the spkr wire coming from 2.5mm jack.
17. do step 16 for another wire for remaining spkr.
18. connect the common of 3.5mm jack with the common of 2.5mm jack(which is one the button).
19. now test ur handsfree.
Precautions and trouble shooting.
1. Remove the enamel insulation from wires porpely else they will not work.For removing, either use some solvent or burn them slightly from edge.
2. Do not short the connections.
3. if ur able to attend the call but ur voice is not going to other side inter change the comnnection on mic cause mic contains a diode which remains in forward bias in only one direction of current. so interchanging of wire will give u opposite polarity which allow the forward and reverse bias in proper direction.
AWESOME!
WOW MAN!
cool guide, thx man! i'll try that as soon as possible...
cheers,krz
Nice!
Good!
thank you! I\ll try to DIY this for my toshiba G900, as I lost the adapter. I'll use a 2.5 mm jack from a nokia headset and a 3.5 mm socket
Great post! Nice walk-through.
Respect
Tnx man, this helped me alot!
Greetings Devs and people
I have a problem with be wired headset, the headset button the earphones are fine the resistance changes from infinity to 98 (~~100) ohms which is fine but the phone does not respond to the clicks:crying:, the mic works, the speakers themselves are fine, now the tricky part though the phone does not respond to 100 ohms the phone responds to 0 ohms and even multiple clicks by shorting aux(button) and gnd (ground), now my theorie is that the the power to the earphones aux pin has dropped somehow and i need to increase that.
Hope someone can help.:fingers-crossed:
I have root and i installed adb on my comp for some reason.
I am a noob to a pro and a pro to a noob, ie in the middle.
Thanks for any help!! :fingers-crossed:

Tests show that it is responding to 30 ohms
Hello,
I am looking forward to buying a decent headphone. The headphone's impedance is 47 Ohms. Usually, the lower the impedance, the less the trouble of powering it properly. Obviously, 47 Ohms in above the average impedance of earphones. So can someone here with a set of headphones with impedance close to 47 Ohms try it with the HAM2 and see if it gets properly powered.
Thanks.
I own Sennheiser HD 598, and even though the large connector requires an adapter to fit into the small headphone port of the phone, I did try it, and found the max volume to be just 20% shy of where I'd like my louder music to be. These headphones supposedly are 50ohms.
