mda, carkit and gps

Hi there,
I've got the T-Mobile MDA with the CarKit and bought a Royaltek RGM-2000 GPS Mouse. Neither the CarKit nor the GPS Receiver have descriptions of the connectors. The CarKit has an 4-pin socket-connector, the rgm-2000 comes with a 5-pin mini-din-like connector I've never seen anywhere else before.
Has anybody got any idea how to get these things together?
Regards
Christian

gps mouse connect to XDA car kit
I have the same gps mouse with XDA car kit.
Try this.....
You must oben the connector for power supply.
On the circuit are the letters R2, T2.
Connect R2 to the green wire of the 8 pin car kit connector.
Connect T2 to the orange wire of the 8 pin car kit connector.
Make a bridge from brown to red wire of the 8 pin car kit connector.
It still works.

220V adapter replacement for cradle

My 220V adapter that conects to the cradle is broken (gives only 0.7-1V).
According to O2 NL the 1 year warranty is only for the XDA itself, and they seem NOT to sell the 220V adapter separate!
Any ideas if a universal ~220V / 4.5V or 5V adapter should work with the cradle???
Marco

If it is a USB cradle, you can also modify it, to get the power of the PC directly.
Normaly all universal adapter will work. You just have to take a look at the size of the connector, polartiy of the connector ( + and - ), and the voltage of it. I think the power consume is low, so that you don´t need a Adapter with 100W...

I use the Adapter of a Nokia 6310 on the road.. it has 5.7V and the same plug as the XDA
Fidl

Does the Nokia adapter works 100% oke? Because it is just 500ma and the original XDA adapter is 1000ma?

Yes it works ok!
I am using it for about half a year now most of the time and i did not experience any problems

220V adapter
Hey
i needed to have 2 adapters for my XDA.
one for the office and the other to my house.
so what i did is i bought a direct USB XDA charger for 15$ and a FIXED 5.0 volts,1amps power supply from some phone srore - 5$.
im a computer tekkie so i got myself a USB female connector (you can buy the in a computer store for 3-5$) and i connected the VCC+ and Ground of the USB female connector to the power supply`s + and -, VUALA! its a perfet charger.
you can disconnect the USB cable from the female USB and use the cable so sync.

Thanks for the feedback Fidl.
Smart thinking Sonic ... as I already have an USB sync/charge cable this is a nice option

XDA to GARMIN GPS cable

Is the serial cable sold as hotsync serial cable OK to connect the XDA with my GARMIN GPS III or is it necessary to put between them a null modem adapter, which was necessary with my old iPaq ?
Thank you for any answer.
Vince

You need a null modem adapter between the 2 serial cables.
But that is all you need.

Portsmith MobileDox Serial to Ethernet Adapter (PS6U1SE)

Has anyone tried out the Portsmith MobileDox Serial-to-Ethernet Adapter (PS6U1SE) with an XDA? I think that in conjunction with a Hot Sync cable, it should be possible to connect the XDA to an Ethernet Network.
Any views?

It doesn't help any of us now, but I hope whoever is developing the XDA II is taking note. There ae a lot of features on the iPaq that we would like to see on the XDA II such as usb master and slave connectivity SDIO standard bluetooth, etc.

XDA -> Laptop USB, GPS-> laptop USB, are they the same

I don't know much about USB. I was thinking coming up with ONE cable with three connectors like the one I draw blow.
Code:
XDA -------USB (to laptop or ac adaptor)
|
|
GPS (the generic GPS connect).
NOTE: the ac adaptor output port is an USB port
it serves for three ways
a), XDA -> Laptop, charge and syn in the same cable, draws power from laptop
b). GPS -> laptop, draws power from laptop
c). XDA -> GPS, in this case, USB connector connects to the ac adapter and power both GPS and XDA.
I believe the XDA---USB cable can be purchased easily. I can break the cable and somehow insert the GPS connector. since GPS only used a power pin, two data pin, a ground pin, I figure I only need to find out how to get these four pin into the original cable.
My question is
1. do I need any USB-serial sort of convertor between the lines? Or it is ok to connect GPS(serials signal) to USB cable
2. The ac adapter was to power the XDA which I blieve is 6V, and GPS needs 5 V, is it OK?
3. anyone alreadys knows how to plug the four GPS pins to USB cable? would save me a lot of trouble.
It would be cool to have a cable connects between all devices. If you can care for a DC-AC convertor in your car, this set should solve all your problem anywhere.
help is appreciated.

Most GPS units are serial. The XDA does have serial, so you can use that. You only need to connect the ground and two data pins. Specified input power for the XDA is 5v.
You can see what I did with a cradle to make a car kit here:

This is a pin spec and photo of the connector:

There is a source for bare connetors, I believe the link is here on the XDA-Dev site somewhere.

Re: XDA -> Laptop USB, GPS-> laptop USB, are they the
It is possible. But note:
1. I assume you are using a serial GPS (with appropriate wiring), then it is OK. USB GPS CANNOT be used.
2. USB sync cable is wired to tell XDA that USB sync cable is connected so as to "wake up" the USB port. In such case, I do not know wheter the serial port can be accessed. As such has not been done before you have to try before you know.
I would suggest you make a cable just for GPS use, and use another cable for sync/charge (this is quite cheap), unless you found that your original idea works.
