22pin connector for MDA/XDA III anywhere?

[dev_dme]

Hi!
Anyone fonud out until now where to get the 22pin connector for the MDA/XDA III device? It has changed a bit from the iPAQ 3800 style, so accessoires for I/II won´t work :(
Furthermore, has the pinout changed?
What I need is a cable for connecting my GPS-reciever, or the parts to build one.

Thanks in advance,
Danyel

OH NO, you are saying that the MDA II accessoried, chargers, etc., won't work with the MDA III?

[dev_dme]

Well, it looks like that...
I have an USB-sync-cable, car charger and my GPS-reciever. Without forcing the plug it won´t fit into the new connector.
The new one has a gab on one side and two little pits wich fit into gaps in the devices connector.
I´ll post a picture of the old and the new one... MDA III´s camera is not quite good for macro-photos.

[dev_dme]

Well, I have "reconfigured" my old GPS- and USB-cable. It´s just takeing away some of the plastic on the connector. Both cables work fine for the MDA III now, take a look at the picture:

hey folks,

i try my best english!!!!

at dev_dme
i got the qtek2020 from vodafone D2. now i want to plug my usb gps reciever with sirfII chipset to the pda. 5v for the usb power comes from accus. this wouldn't be the problem i think. but how i figure it out which connectors of the pda are the right connectors for die TX and RX of the reciever? and the final question: is this what i want to do (usb pc gps reciever at pda) possible?
if you want t answer me in pm dann auf deutsch ;-)

thanks.

Therefor you´ll need a USB to serial converter, as far as I know.

hi, you need original connector you can try with 2020 22 pin but after some days or week you will damage you QTEK 9090 and you not be able to use anymore the connector! i suggest you to buy ORIGINAL see here available : http://www.bluetrade.fr/achat/produit_details.php?id=76226http://www.bluetrade.fr/images/BT-PDA-QT-903.jpg

i hope i'm logged in now!

to dev_dme you missunderstood me? i have an usb gps mouse so i need a seriell one. and there are no converter from seriell to usb.

to last guest
i think i posted in fals thread. i have a qtek 2020!!!! no 9090.

There are USB to serial converters made by Iogear, search the web. You would have to redue the cable to connect to your Qtek. But since you have bluetooth, though the old one away and get a blue tooth GPS, much nicer.

[aimchr]

converters from usb TO seriell but not from seriell TO usb. i'm right?

[paulmc]

The USB driver was on laptop to change the port to a serial port but the communication was bidirectional.

You could also look at maxim semiconductors, I know they make a chip that converts serial to USB but I couldn't find it.

but i need usb to seriel converter..... i want to use an usb device at a seriell port

[paulmc]

They have a device, I saw it in EE Times twice (as I said I need that) that will do exactly what your looking for. It would connect to a USB device, takecare of all the protocal and then spit out serial bits of the data. I beleive the formating (USB-serial bin/ASCII, bit ording) was able to be changed via reg settings.

maybe search EE times website.

Well, your GPS mouse is a USB client (slave). You can only connect it to a USB host (master), which the XDA II is not. So you would need an adapter that contains a USB host. As paulmc says, they seem to exist, but seem to work only with "big" Windows (they need drivers), and I am quite sure they are really expensive.

I really recommend you get either a Bluetooth or a regular serial GPS mouse. Both are easy to connect to an XDA II.

hello folks,

information for all users they helped me: now i bought a holux gm 210 gps receiver with ps2 connector. it should be one of the best.

but now new questions:
1. is there a german plattform like this in the internet? which one?
2. how can i get 5VDC from a the 12VDC connector in a car? i dont need 4,5 or 6V!!!!
3. who know anythink about the holux gm210 voltage supply (spannungsversorgung). how much V need the gm 210? exactly 5VDC?

thanks

bye Christian

1. There are several. Try www.pocketnavigation.de for a start. :-)

2. There are voltage regulators you can buy. But be very careful, the voltage in a car is full of spikes and other nasty things. You need a good voltage regulator if you don't want to endanger your new Holux. The usual solution is to buy a holder for the PDA that also has a connector for the GPS mouse. This gives you a well filtered voltage for your mouse.

more more more :D

maybe its silly but i dont wanna buy i want to build it by myself.
because i want biuld an accu-charger for my qtek too. it should supply the gps mouse too!!!
i cant describe it better in english. damn..... :evil:

[aimchr]

also i need thias speciial pda connector for the mdaII (aka qtek 2020). where can i buy it for low?
and some more important for me: i need information for the pins. what pin for which signal?

[DUTCH]

Does anyone know if the pin-setup for the 'blue angel' aka Qtek9090 is different then the 'Himalaya' aka Qtek2020?

I want to connect an external speaker and microphone to it (described here (http://wiki.xda-developers.com/index.php?pagename=Connectors)) but i'm not sure if the pin-layout is the same :roll:

Thanks!

Grtz,
DUTCH

anyone found the pinout for QTEK9090(Blue Angel) yet ?
please share.

Hi.
I was developing DIY carkit for my MDAIII.
It seems that pinout is generally the same for MDAII and III with slight differences.

pinout :
http://pdaphonehome.com/forums/showthread.php?s=035a9aafb70556d6ff16a4a574ca95ea&threadid=7683&goto=nextoldest

It seems that MDAIII doesn't have a dedicated seperate GND for audio,
and it doesn't have IN_CALL pin (too bad).
The mechanism behind CAR_ON is vague (it's well explained for MDAI and II), because MDAIII user report different things.
Some people say, that pulling CAR_ON to GND is the only way to get audio out through CAR_AUDIO_L&R.
Some say, it only redirects call audio, and to redirect all audio you have to replace wavdev.dll (with taken from www.thb.de)
To make it even more complicated... my MDAIII does always redirect ALL audio without any ingerence (weird, isn't it).

Currently I'm having problems with audio quality.
I'm having lot of interference due to common GND for car, charger, and audio.

[unclebulgaria]

In-car votlage is "noisy". You will need a small inductor on the input to take off spikes. Use a zener diode to limit the input voltage to a maximum value (and protect yourself against reverse-wiring!). Infineon have a 60V input, 5V out regulator which I recommend.

You may also want to use some capacitance in case of voltage dips ...

I got mine from 02 for £10 + delivery.
