Hi Guys,
I have just got the fantastic little E72 and it is great in almost every way. I want to be able to use my Shure headset with it so I need the adaptor that everyone else wants to find it seems. I have a HTC adaptor but it will not fit into the socket. The socket on my E72 has 5 pin holes and both sides of the interface are curved. The HTC adaptor has one curved side and a straight side so it will not fit in. The E72 does use the usb connection for its headset and audio output but when I did find a Samsung adaptor with both sides curved that did fit into the phone socket it still outputted the music to the external speaker so I am at a loss. There are, therefore, different types of mini usb connectors. Can someone tell me the exact spec of this one fitted to the E72 and possibly where I might get an adaptor that will work??
Much appreciate the help with this.
usb cant be changed to 3.5mm or any type of audio
the reason the htc one dont work is the same reason it dont fit
it have extre connectors which carry analog audio
normal miniusb is a serial digital interface which dont carry analog audio
and usb headsets for pc are really external audiocards which make the serial digital data to analog audio
and that require the ability to usbHost which few pda's support
Many thanks for the explanation. However, my phone came with a stereo headset with mic. I currently use this for listening to music but the quality is not good. Does this not mean then that I should be able to get analogue signal from it??
Please forgive my ignorance; I am learning!!
it all comes down to where you connect your headset
if it's the miniusb port benQ got an extention of miniUSB like htc's extusb
if it's a 2.5mm minijack like older htc devices used you can get a conveter to 3.5mm
The only port on the Benq E72 is the mini USB one. There are no other jacks. The problem is that both sides of the metal housing within this are curved so the HTC one (with one side of the miniUSB adaptor straight) wilkl not fit. I did manage to find and buy an adaptor that was branded Samsung and when I fitted it into the miniUSB socket on the phone it would not work. The music continued to play through the rear speaker even though the adaptor was connected. My supplied headset connects to the phone through the same miniUSB paor but again the metal housing of the miniUSB jack is curved at both sides. I hope this explains better.
as i said then miniUSb should not alow audio at all on the device
and htc use extusb which have more legs then miniusb so if it dont fit
it should not be because of any curves
does your benq device not alow headsets at all ?
if it does how are they connected?
The only connector on the Benq E72 is the miniUSB port. In the attached pic you will see the connector for the wired head set on the left and the miniUSB to standard USB for connection to the PC on the right. I looked inside the silver housing of the connectors on both cables and they seem to have 5 pins along the top (widest) part with the main section being hollow. Now the miniUSB housing on the actual phone does have a plastic inside with 5 pins and , I guess, more connectors along the top of this for the 2 cables. I am to assume that the plastic insert in the phone itsaelf is for the electric charger. There is nothing more that I can give you except to say again that the miniUSB is the only connector on the phone.
if it support headsets connected to the usb connector it must be using some sort
of special usb connector like htc's extusb
i would look at their site if they sell converters
Thanks, as I said the only way to connect the headset is by the miniUSB port so it must support audio. The issue is that the HTC miniUSb headset has a curved side and a straight side so it will not physically fit into the Benq E72 connector. I did get my hands on a philips miniUSB that did fit into the socket on my phone but the music still outputted to the rear speaker of the phone. So, my question is, is there different types of miniUSB wired internals? It would seem so. And would anyone know which would work for the Benq E72 windows mobile poweredsmartphone?
@ 17-apg,
Sorry for this off-topic post. Im planning to buy benq e72 because my o2 xphone2 is too old. Can you please give brief review of the phone, as a user. Is it true that it is laggish? Thank you.

No problem ,,
I have the device for over 2 months now and like it a lot. Had a HTC S730 before which was thick and cumbersome and I didnt really need the keyboard. This phone, in contrast, is very light and thin. It runs WinMo 6.0 and I do not find it slower than the HTC in any way. On reflection maybe a little faster even. It is very competively priced as it includes bluetooth, quad band radio and wi-fi. The bluetooth also carries the A2DP functionality. The screen, whilst a little small at 2" is very bright and clear. The keypad has large buttons and is very tactile and positive when texting.There's a 2 meg camera included as well as the microSD slot with a max size of 2GB. You can, however, with software, increase this to the norm of 6GB which I have done. Also the rear speaker (built in) is a reasonable size and therefore can play a decent sound for music if you are travelling and in a hotel room for example. And finally, it has little important assets like the ability to turn on auto redial, a button on the left side which when pressed and held will open the text messaging in a send window. There is also the facility to adjust the screen brightness as well as an internet radio and ringtone editor. All in all, for the price, I definitely recommend this phone. I have bought four more since for friends of mine. They paid of course!!! Now all I need is the miniUSB to 3.5mm audio jack sob sob...
Can you tell if a lanyard can be linked to the device - and where? On all available photos on the net I have not seen any holes for fitting the lanyard to :-(
I am really tempted to get that one as well - escpecially as it is the ONLY (!) smartphone with only a normal keyboard that can use microSDHC cards (after installing updated drivers). They seem to double in size every year - and if the standard is fully supported 6 or 8GB (as reported sucesfully) should not be the limit.
Lanyard
Yes, you can connect a lanyard at the top of the phone. If you can see the top view of the device there is a little hole there. You simply slide off the back cover and fit the lanyard to the designated area on the main body of the deivce (very easily) and then slide the back cover on again.
Now we just need a cooked 6.1 rom for the device!!!
Thanks - I found a set of pictures at a Taiwan Review site (http://www.eprice.com.tw/mobile/talk/?prod_id=2621&tid=3430647&page=1&list_page=1) - this tells it as well
I was only looking for a small device that can read memory cards > 4GB and this is the one now. Otherwise my Tornado in the house of a Robbie still perfectly fits my need. I also tried WM6 and WM6.1 on that - but fell back to the original WM5 there.
Just can't wait to get it in my hands - it was really a bargain on ebay. Search for benq E72 there and you will see a guy in London selling refurbished E72 for just 69 GBP (9 of 21 left). I just could not resist for that price, sigh...
BTW - on topic: did anyone try the Motorola mini-USB connectors - for the Razor and alike?
I dont think so. DO you habve one that you coulkd try when you get the phone? If so, let us know here cause I would really like to use my own ear buds.
BTW I think you will love this phone! It really impresses me. And also Expansys anre selling brand new ones for about £90.00!!
Is there a WM6.1 for this? Thanks.
Benq E72
Not thatI am aware of. I know that another avid fan of the E72 has requested ROM cookers to try to come up with the 6.1 version bit I am not sure if anyone has taken up the challenge.
I hope that it will happen soon ...
I have received mine in the meantime, but the refurbished one was delivered with a non-fitting headset :-(
Well, it fits mechanically, but there is no sound at all. It looks like a cheap replica of a Motorola Stereo Headset - but also a normal Motorola does not work in this socket. So I am out of any possibility to measure the data of the socket to build an adapter. I complained at the dealer - hopefully there still is a working headset available!
Otherwise the device is nice - only English language installed though for menus and T9.
bye
tobbbie
With some help from Taiwan - the USB wiring for the headset is identified, see my blog article at http://tobbbie-benq-e72.blogspot.com/2008/12/hacking-usb-headset-connector.html for more details. The main information is:
....So the final result is then for the numbered pins of the USB connector (1-5):
Must be connected with a resistor less than 200 kOhms to ground (pin 5). The voltage will rise briefly to battery level but then drop back to 0,16 V to stay there. I suspect that accepting calls with the headset button will introduce new functionality here...
Speaker channel (l,r not checked, source indicates right here) - must be connected to a speaker or a pulldown resistor at device-headset connection time.
Speaker channel (l,r not checked, source indicates left here)
Microphone channel (checked to work with Audionotes)
Grounds
So luckily no complicated electronics - get your soldering irons ready!
BTW: have still not received the original headset :-(

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

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.
Grtz,
Jos
I am attempting to house an i-mate PDA2 in a custom enclosure (for a product that we make). I want to modify the 22 pin connector on the sync/power cable but I cannot find a pinout.
I need a picture or diagram of the 3, or is it 4, rows of pins with pin numbers, pin function and connector wiring (jumpers, etc.)
Anyone know where I might find this?
Before you get crushed by the "rtfm" type posts, I humbly direct your attention to the "connectors" link on the front page of this site, which will lead you to: http://wiki.xda-developers.com/wiki/Connectors. It's an extremely useful page!
OK, I told you so now you tell me; what're you guys making?!
I did check out the "connectors" page and it is helpful.
However, what I am looking for are details of the inside of the cable connector. I took one of these connectors apart and it's not the easiest thing in the world to figure out which pin goes to which on the PDA side or what the number system is.
So, it would be very helpful to know if someone has already gone through the unravelling.
In a nutshell, our company has developed a technology that uses ultrasonics to measure load in bolts both during and after tightening. The PDA is the platform for the controller of the tightening and inspection tools.
Sorry, I assumed that you'd not looked at the connectors page because I used it to figure out (I think) what it is you're after when I was trying to make my own sync/charge/gps connector.
If this is something that you can't resolve with a multimeter, then I guess you must be looking at an interesting connector! I'd suggest posting a couple of pics of the connector with it's top off lined up with the phone's socket. That'll make it easier to figure out what's what!
The load detector sounds cool, I'd love to see a screenshot if you've got one.
Yes, it can be resolved with a multimeter - I was just looking for the lazy way out!
I have attached a photo of the prototype unit - not the most professional representation, but a decent one nonetheless.
That looks cool! I love it when people *really* use these things.
If you open the connector up and see 2 (staggered) rows of tiny, really hard to solder :lol: pins, pin 1 (left side of the phone connector if you hold it bottom towards you, screen up) is the bottom left pin.

^ bottom left is pin 1. Hope this helps, sorry I had to bath the baby earlier and was typing whilst holding a somewhat sticky little girl
Thank you!
Subject: PDA2 sync/power cable connector pinout
On this thread, I was thinking of using the desktop cradle as the base for a mobile mount.
But the pin-outs for the PDA2k are not easily found.
The connector link now appears to be at:
http://wiki.xda-developers.com/index.php?pagename=Connectors
This page seems only to refer to the Wallaby and the Himalaya.
Is there a specific page for the PDA2k or does anyone know if the pin-outs of the 22 pin connector are the same for the Wallaby/Himalaya as they are for the PDA2k?
-I found elsewhere that Pin 19 was different.
Are there any other differences?
Also somewhere amongst the threads there was a mention of the pin-outs of the 2.5mm audio out /mic in was different or was it the switch on the hands free headset?
I have trawlled the site and it has eluded me so far for a consiolidated posting on the connectors for the PDA2k.
Can anyone point me in the right direction?
Perhaps I am just deluding myself
Thanks in advance
If you lost your marbles, would you know where to find them?
harrier mounts and connectors
I wouldn't use the desk cradle to make a car mount. IMO the car mount from Clicon (www.clicon.com.au) is better mechanically than the desk cradle, and already suited to vehicle mounting
There are a number of variants of their kits, but not many that suit my pda2k-evdo. The ones that do suit are:
- plain cradle with no connectors, but leaving the pda2k connector exposed and accessible
- plain cradle with "passthrough" connector - so connect your own charger etc to the bottom of it. Note that this passthrough doesn't support the two lugs that some pda2k plugs have (eg the charging dongle that came with the pda2k-evdo)
- cradle with lighter-socket charger. The charger part is actually removeable; they've just screwed the car charger to the cradle.
The lighter-socket charger mentioned above has a small board inside the connector with Tx and Rx holes labelled. It looks like it was designed for making a serial+charge adaptor.
I have a separate RS232+charger adaptor cable ("suits XDA IIs") which looks like it's charging, but really just keeps the screen on and runs down the battery quicker. It turns out it only has one V+ and one Gnd pin connected, as opposed to 3 of each listed on the Connector page on this site. Makes me wonder whether the 3 pins for V+ actually all have the same function. Time to mod the connector...
Gregnash,
I agree with your summary,
and I have looked at the available in car cradles/holders.
I have already ported a XDA1 cradel with audio/mic,USB and power to see if the connections can be done successfully.
All worked except for the mic as I need to find a 4 polo 2.5mm panel socket so that it switches on hook.(this I assume is pin 19)
You are right, by itself the Harrier cradle does not securely hold the pda in place as there is lateral movement.
What I am trying to achieve is a "all in one" in car cradle/holder.
I have sucessfully mounted a NOKIA passive anennae connector to a stand alone generic brand pda holder.
This as you said allows the connector to be exposed for charging.
I have used this method with a 9db external (old analogue antenna-funny that, you can use them for CDMA) antenna or a 9 db through glass antenna.
Currently the system is clumsy as also I run a bluetooth external GPS and route the audio from the 2.5mm socket to the cassette player adapter.
-(no audio IN in this car radio)
What I was hoping to do was to incorporate the Nokia Passive antenna coupler at the rear of the Harrier cradle which would put slight pressure in the forwards direction to both make an antenna connection and more secure and stop the Harrier from moving.
(Another flash idea is to strip the inductance plate from the coupler and mount a antenna cable socket on the coupler face so that it aligns with the antenna out from the Harrier)
With the audio out /mic in and charge through this connector , I am hoping to eliminate all of the wiring as I can conceal the wiring back inside the dash.
The only other thing is the on hook switch for receiving calls.
As you can probably guess I probably have too much spare time.
Perhaps Bluetooth In car kit will by-pass the need for the physical connectors as it is software driven.
But I have heard of so many bad reports of BT connecting to the phone that it appears to be pot luck if I find one that works.
What about this arrangement:
1. Harrier cradle -with antenna coupler if secure,
2. bluetooth in car (cigarette lighter style) hands free-Blue Ant etc,
3. audio out from cradle to radio ( for GPS instructions and playing mp3 from Harrier) freq transmitter(powered externally).
4. bluetooth GPS external antenna
mmmm..... maybe a bit of an ask but it does allow a "drop on cradle ,push forwards to engage antenna and forget" action.
Maybe I am off with the fairies, what do you think?
Any comments would be appreciated.
For antenna supplies you can try this site http://www.wpsantennas.com/ basically I think it would boost reception back to 3 watts. 3 watts is the same wattage as the old car mounted mobile phones. Mobile phones operate on 0.5 watts. No wonder our reception sucks in so many places.
Hook the antenna into a car cradle and some type of handsfreee switch for the radio, and you have a very powerful, very mobile 3 watt mobile phone with great reception.. if you got carried away you could even connect your car to the ppc and moniter engine, fuel, etc. Plus a GPS.. and oh the possibilties are endless.
Johnno's ambitious car kit
Yeah, I think you do have too much time on your hands
Sounds like a plan, though, and I'd like to know if you make it all work. The antenna couplers I've seen take a bit too much force for a "drop in, push back" arrangement, but one designed for a different phone may do the trick if it fits.
btw, my interest in serial is for wired GPS and to talk to the engine management computer (not at the same time, or one will have to be bluetooth). Even better if they can be powered from the same cable.
dougnet
Thanks for the link.
I actually had thought of this proposal.
I actually contacted tht crowd (amongst others) about two months ago as I was thinking the same as you.
They answered that they are not allowed to export GSM or CDMA amplifiers to Australia.
I think it might be that new "Free Trade Agreement and respecting our telcos" we now have with the US where things are not really "FREE".
Probabably if I asked 12 months ago it might not have been a problem.
Nice products.
Trouble with Antenna couplers , is that you lose at least 1.2db + in the cconnection.
You you really need a grunty antenna or output.
".. if you got carried away you could even connect your car to the ppc and moniter engine, fuel, etc. Plus a GPS.. and oh the possibilties are endless. "
Now I have an automatic car so rev monitoring would certainly be overkill.
I get your drift, though thanks for the input.
gregnash
I will have to see how much force is needed to engage the pda.
Don't forget that at least the same force will be needed to disengage it as well.
Mmmm...good point, this means seeing whether a panel mount socket is available in this cofig.
Wouldn't have a clue who might sell panel mount sockets suitable for the Harrier/Blue Angel?
I am not sure how a cable termination would cope with the forces needed.
The fixing method would have to be substantial.
Serial connections to the car comp?
You would probably need to hack the code to get access to it I suppose?
But if you could tap into the on-board engine management computer, then you could change the air to fuel ratio at the injectors and lots of other cool things like disengage my engine cut-out at 190k/per hour and have some real fun!!!
Not much fun at 190K/h and the engine stops-no brakes, no steer!!!
Must be for the rev heads-NOT ME!
I will investigate the force on the antenna connector to see if this is feasable to mount.
I will let you know what I find.
Hi all.
Thanks for the encouragement.
Well life is full of compromises!
So long as you do not require audio output and you are happy with the Harriers speakerphone volume, I think I have a home solution for the uninitiated.
1. I have a "generic brand mobile phone holder-one of those adjustable in width ones- full width just held the Harrier nice and snug.
2. To this I mounted at the bottom (after removing the locking latches)
a USB car charger cable -with no modifications.
-Actually I pop rivetted the backing shell to the holder.
3. I then mounted a Nokia a passive antenna coupler and sculptured the holder-so that it fits at the right height and to the left of the Harrier.(where the antennae is on the Harrier)
4. I then mounted the holder onto the dash of the car (my choice as I put it though a removable panel where a digital clock is fitted in an other model, and passed the antenna cable,and the charger cable to a cavity in the dash.
5. Here I supplied a cigarette socket with 12 volts and connected the charger cable.
What I ended up with was a car mount that was a "drop in" style that
was easy to build without any fiddly soldering of connector pins.
I actually did make it with USB and audio out but these were surperflous as at the moment I do not have an audio in for my car radio or an amp to drive it.
But I just wanted to see if it could be done.
This is why in the picture you can see electrical tape around the cabling.
(This is because I had USB,Audio out and Car charger cable.)
Once you have this type of holder, it is not hard to get a new holder and move only the antenna coupler across ( I would think that the new connector would be different from the Harrier)when you upgrade to a new PDA.
In summary:
Compromise 1.
1.2db loss at antenna coupler-using 9db external antennae so I can live with that.- but no nasty "push to connect" hassles.
Compromise 2.
Audio out does work but the level is so low that it needs good amplification , this I will not follow up until I get a car radio with audio in.
Rely on Speakerphone fore the time being.
I hope this is of help to those thinking of this kind of project.
I hope the picture is reasonably self explanitary.
If you have any questions just let me know.
Hi all!
For sound out, there are adapters (I already have one), which convert from that custom 2.5" jack to a standard 3.5" - which even let the built in microphone active. OK.
But is there any adapter for the opposite? Converting the microphone / sound in part of that custom 2.5" to an e.g. 3.5" - so that some standard microphone or some other sound pickup could be attached?
Wether built in speaker would be left active or not isn't relevant for me.
Background: I have one of those programs for tuning musical instruments. It works fine with the built in mic in relatively silent rooms and for acoustic instruments. But imagine beeing on stage between two songs while the crowd is cheering!
If no such accessory is available: I would spend some extra Euros for a second hands free thing, cut off the side with the 2.5" plug and tinker a 3.5" on the open end.
But will this work - or have I to include some resistors or such?
Thanks, greetings
Manfred
There are such adapter on sales
http://www.expansys.com/product.asp?code=113967&tab=0
As for the issue of resister, I don't think you will be needing any. I've no experience on electric musical instruments, but a microphone is a essentially an active resistor/capacitor that convert sounds to resistance/capacitance-variation and hence electric signals. It does not produce any form of voltage itself (eg. you do not need battery for microphone).
Hence, it depends on your musical instruments. If you were to get the adaptor above, perform a voltage test on all 6 combinations (of the 3 contacts) to make sure your instruments does not produce any form of voltage/current. If it does not produce any form of voltage, you ought to be safe for a direct plug-in.
(oops, did I mix up " with mm in my initial post )
Are you using this adaptor yourself? With a Prophet? Does it work?
Not to appear nagging, but there are three facts that make me doubt:
- the description there tells me, that it "converts the standard 2.5mm three conductor jack"
- which can also be seen on the "larger image" (those pictures at expansys often are near causing eye cancer >;-) ), where the plug has *three* contacts
- description also tells us, the adaptor converts to a "3.5mm Mono Headphone Jack".
Well, the jack of Prophet has *four* contacts, and sound out comes in *stereo*. I guess that: tip and first ring are - stereo - out; 2nd ring is mic in; last "ring" obviously is ground. This I take from the fact, that my adaptor for standard 2.5mm to standard 3.5mm stereo earphones really delivers stereo out, but the internal mic is still working.
So I also guess, that this adaptor here has e.g. *mono* out on tip, mic in on 1st ring - and ground on third and last ring - which also would lead to connecting Prophet's mic to ground.
Or am I totally wrong here?
The question about resistors (and such) comes from looking at
http://wiki.xda-developers.com/index.php?pagename=Connectors
(but that's Wallaby and Himalaya wiring, and with the latter there's also an extra (5th!) "outer sleeve" connector); but you can see in the drawing there, that there are a diode and three capacitors between mic and ground, and serially a resistor (but all without values).
So I fear, that just connecting a (passive) guitar pickup won't deliver satisfying results.
Hmm. didn't notice that one is a mono output. Anyway, can't really find one with mic and headphone out for streo (actually, gave up searching). I guess there aren't enough market for people pluging in their own mic.
As for the diagram, it looks like that, for the micrphone, the circular wiring thing is an inductor, not a resistor, since it is marked as L1. From what it seems, it looks like those capacitors and inductor is there to bias the circuit such that the mic is to be in the right impedance to pickup speech. That is more to "adjust" the mic such that it will gives the correct values (probably due to its small size?). So, if you were to plugin in your instruments directly, the result may not be that good. But probably it will. You may need to tune your software to adjust for this?
As for the z-diode there, it is a mystery to me. Can't think of anything useful for it, except to ensure the mic-in is always >= 0 (greater or equals to zero).
Well, first of all: thanks a lot for your answers!!
I also gave up searching before posting here; also searched for a separate 4-ring 2.5mm plug; but before investing in a second headset just to get that plug, I thought I'd ask here ...
Inductors, resistors et all ... it's been way too long since my physics intensive course on grammar school ...
Your thoughts sound logical.
So I'll get me the headset for the plug and tinker an adaptor myself - without any extra inductors or capacitors. Will see how it works - if not, well, I'll come back here again to ask for the values of them ... and tinker along ;-)
I build an adapter on my own out of the standard hands free headphone which was included in delivery.Unfortuately I had to destroy the case a bit I just made a kabel with a 3,5 mm jack and soldered it on the circuit board and bridged the build in mikrophone.Now I am able to connect a stand alone microphone to my Prophet.
Cheers
you can order one @ http://mobile.brando.com.hk/
@ Repose: you mean the handsfree headphone? I already ordered one at expansys
@ colida: that's another idea, keeping the circuit board. Such, all capacitors etc. are in place ... maybe just looks a bit ugly, you really have to break that little housing.
Any adaptors that will allow me to use proper 3.5 inch headphone jack in place of the mini USB ones ( i dont like the in ear phones) checked ebay and couldnt see anything?
you want get one of these http://www.expansys.com/p.aspx?i=142090 - Mike
Ouch, that thing is both horribly badly designed and prohibitively expensive- it's going to stick out what looks like an inch by itself, most headphone plugs will add another inch on top of that- I need something that fits flush with the bottom of the phone (comes out at a right angle) AND supplies an input for the charger. One can only dream!
The orbit would make a great on-mains Wifi internet radio if such a gubbin existed- hook up some speakers, start TCPMP, sorted!
in which case if you don't like wires stop messing around and get a set of A2DP compatible headphones - the quality is very good, but far more costly than a cable addaptor - the choice is yours - Mike
Might have been worth while if I didn't use an iPod for all my portable audio needs- have you seen any A2DP compatible speakers around?
Looks like there are hacks out there, but no official products, the combination really would just turn the Orbit into an incredibly expensive Wifi radio! But where's the fun in just going out and buying a proper one!
Have a look at the products made by Parrot there are a few Bluetooth audio add on boxes, I fail to see the relevance to WiFi?? as the A2DP profile is Bluetooth - it even works on the T-Mobile MDA-CIII which has no WiFi - Mike
I say wifi radio because I listen to internet radio stations around the house using the Orbit, and the ol' tinternet comes via the wifi doohickey!
A2DP is, of course, a bluetooth profile and would be the method over which I get decent sounding audio from the Orbit to some speakers whilst still having the Orbit plugged into mains so the battery doesn't get sucked dry... that said I think the Orbit will last a good few hours streaming internet radio, although I have yet to put that to the test.
My other solution would be, as mentioned above, an adaptor that allows both the charger AND headset to be plugged in- I can't see this as being technically impossible.
With a brief cursory investigation I have discovered, I think, that the headset uses a proprietary 6-pin connection on the opposite side of the mini-usb connector. The headphones do not use the 4-pin standard mini-usb connector on the other side, but a connector that uses both should be reasonably simple to produce. Ergo it should be childs play for a third party to produce an Artemis dock that contains not only a connection to USB but a standard 3.5mm amplified microphone socket alongside a standard 3.5mm amplified stero audio jack... not to mention a button on the front of the dock for picking up calls and a volume slider if you really wanted them.
Call me crazy, but I want one of those!

Might do the trick even if it is a bit long

Dear lord! You've made my day! Hmmm, a little jiggery pokery and I might even be able to incorporate that into a dock but it'll be fantastic for charging and listening to net radio at work- takes that little extra load off my desktop PC.
Cheers!
Glad I could help

Hi,
Does anyone know if the above would work with a set of mini stereo speakers with a 3.5mm headphone jack (like the walkman speakers i used to have, back in the day...) to listen to the FM radio while charging the phone from mains? Or would you still need the headphones plugged into get any FM reception?
Daft question maybe, but I wondered whether the device would just use the speaker wires as an antenna instead of the headphone wires?
It will work fine, I am going to use mine to connect my orbit to my home stereo and charge it at the same time.

2.5mm 3 pole jack plug
Hi,
Anybody know of an Artemis mini usb to 2.5mm 3 pole jack plug adapter which allows the connection to deliver audio and microphone capability ?
I would like to connet my Artemis/Orbit to the Autocom intercom system on my motorcycle . This uses a lead with a 2.5mm jack plug at the phone end and a 3.5mm jack at the Autocom system end. Both are 3 pole.
Thanks
P.S. hope you don't mind me jumping in your postings

try doing a search for "2.5mm"
A very good Items for the Artemis on EbaY :

Is this so you can listen to music from the Orbit? I've had difficulty on my bike with this...music cuts out and wont restart after phone call is over. In the end, I bought the Autocom bluetooth dongle and now bluetooth the Orbit to the bike. I get phone calls and GPS just fine, but I use a wired iPod for music.

Does this support the Artemis? It isn't in the list....
There was a posting for the mini USB PinOut some Time ago. Look in the wiki Section to find it. Here is what they showed up with.
Maybe This will Help someone to build their own Adapter or whatsoever.
Greetings
Jabami
so what was the general concensus with using Autocom? Did the 2.5mm jack work?
I want to avoid using the bluetooth option on autocom, since I might just as well go for a Scala bluetooth headset instead if the jack doesnt work...
I was wondering if i could grab a normal mini-usb to usb cable, cut the normal usb ending and sold the audio wires to a 3.5mm jack, so to use it with any audio device.
I just need to know wich of the wires inside the usb are the ones wich carry audio?
if i'm able to make it will make a tutorial although my english it's not that good
just so i don't have to break the original wire.
thanks
Not really - it can't be done
Here's the pin-out diagram
http://www.tracyandmatt.co.uk/blogs/index.php/2006/09/10/htc_hermes_usb_connector_pin_config
but you would noticed that the "miniUSB" socket on the Touch is actually a 2 in 1 device, a standard mini USB only have the bottom connection which deals with normal data traffic and charging, the top connectors carries the audio which the standard mini USB don't connect to (physically it can't).
But you can buy specially made adaptor to provide USB to audio sold on this site or elsewhere, such device make use of the more special connector to connect with the audio side.
I have 2 of such adaptor, they cost around USD15 a piece. Yes a bit more expensive than normal USB but they look neat
yeah, i wrote the post beforing having my elf, wich luckily was en ELFIN i'm really happy with it, i received it 3 hours ago
close this post

I paid mine about 3/4 euros....
Have a look here:
http://cgi.ebay.com/ws/eBayISAPI.dl...egory=10364&tc=photo&_trksid=p1713.m153.l1262
And this is STEREO quality....
i'm from argentina so, i can't buy on ebay. The only adaptor here cost aprox U$S 35
that's expensive but it's my only choice
Just purchased my adapter from ebay and got it the other day... Works great. I have it connected to an FM transmitter so that all the audio (mp3's and gps audio) out to my car strereo.
Right after I purchased the unit I looked around and saw one with a built in microphone so I could have made it into a handsfree unit and have the audio go over the car stereo... DOH! I may do the upgrade in the next month. The adapter I got with shipping only cost 8 dollars.

cbaty,
i'm from brazil and i found this site about adapter http://www.expansys.com.br/p.aspx?i=149937...
i don't know if works very well and if is possible to sell to argentina...
but, you can try....
I purchased a mini usb to rca cable advertised for use with the Moto Razr phones. I know that the car charger for those phones works for my HTC. Heck, I could even charge my phone from my PS3 mini usb cables meant for charging controllers.
I received the cable today and I can't get it to work with anything.
Initially I tried it with my car's aux input. No workey.
Tried it on my home stereo. No workey.
I guess my assumption of this cable working for me was wrong. The only way I can get audio out of my HTC is with the supplied headset. Does anyone know how to convert that to RCA instead of 3.5mm?
Thanks.
The regular mini usb cables don't carry audio from the HTC Touch. That's why the earphone's they give you have a different connector, it looks like a mini USB but it's not.
It's easy to take apat the HTC earbuds and splice them to a 3.5mm jack so you can use standard earbuds. I did it and it took less than 5 min. There is another thread about it here somewhere with a step by step and everything.
i hav modified the original hands free, removed the earpieces and soldered a 3.5 mm socket into the call receive / volume adjust part. working fine so far ...
I did the same, but I broke the mic while soldering
Does anyone have the wiring diagram for the elf handsfree so I can know what I am trying to fix?
abt d port
hey.....u get d branded mini usb to 3.5mm jack in htc accessories.........jus chk it out buddy....

There are two types, one is a usb connector and a short cable to a earphone socket, and one is all in one...
I can get them in the UK on ebay for around $5 - add the same again for postage, and I'll get one and mail it to you - Paypal me when you get it... if you want me to, let me know and I'll work out the exact costs.
Here's some links, like I said, find one you want, I can buy it here and ship it for you.

If I am not mistaken, you can do one better - not only you get USB to 3.5, it will include the handsfree clip-on controls (mic, answer button, volume etc), allowing you to use the earphones of your choice. Which was the absolute must for me, because my ears are too small for the regular plugs. Not only that, most earphones included in the box are average quality at best, none will beat Sennheiser anyway.
I got one like that for my LG Prada, because the buggers use proprietary connector, which sucks. Paid $4.50 USD with FREE delivery to New Zealand. Can't beat that, I think. Let me see if the same seller has one for Elf.

Yes, there are a few options - I personally don't like the handsfree adaptop becasue you end up with too many wires in your packet... I use mine with some sennheiser phones with short cable, to make it neater.
I do have a set of Motorola S9 bluetooth headphones which work great, but you do get the very occasional cut out, and you have to remember to keep them charged up....
I think the all-in-one-block adaptor is the neatest for keeping everything tidy and untangled.
i got the A-200 HTC audio adapter it's gr8 ... usb (IN) and 3.5 , 2.5 , usb mini for headset and usb for charger (OUT)
it's really gr8 .. but i have a small problem ... sometimes the voice dailing work by itself !!
i mean the voice speed dail prog works and ask me to say the name to call ,,, and as the music in on or if iam talking ..the device go wiz the nearest voice tag and call !!!
and when i called the service center the told me tht may be the prob, with the adapter!!
anyone have the same prob ?
help........Who have 'iswish'
I come from China, who have the iswish this software? Is it all right to give me 1? thank you!!!!!!!!!!!
wher can I get this in india??
