Can anyone tell me whether it is possible to use a Garmin eTrex with the XDAII / iMate via an Arkon PDA Mount's RJ12 serial port?
I have seen various cables to facilitate connecting the eTrex directly to the iMate (for instance http://shop.store.yahoo.com/semsons-inc/itgaretpdali.html), but there doesn't seem to be a cable available to connect the eTrex to the RJ12 connector on the Arkon, which I'd prefer since I still need to power the Arkon to make use of its speaker.
I'd be happy to purchase a bare-leads eTrex data cable, and then crimp the RJ12 connector on the end, but I'd first like to ascertain what the required pin-outs are, and also whether it'll actually work.
Does the iMate even see this RJ12 port as a serial port?
Thanks folks.
I wonder if MDA I's USB cable should work with MDA III. E.g., miniSync sells one lableled for MDA III, but the plug looks exactly like that for MDA I -- and XP says, USB device unrecognized... Is there a driver to make it work?
You need activesync installed first, once installed your phone should be recognised when plugged in and activesync should launch.

I have it installed for a million years, and it just seems not to notice MDA III with the same cable through which it sees MDA I just fine... I see conflicting reports on connectors -- are they different?
I've noticed there's a site saying it sells a cable *and* a USB driver for it:
http://www.cell-phone-accessories.com/simddacawusb.html
Is there a free driver version available? If you google for
"MDA III usb cable drivers"
you get a lot of cables which look like MDA I ones -- no sping on the left on top of the plug.
Still wondering if all those cables are mislabeled... Anyone has a cable with a new, asymmetric plug like the MDA cradle has?
I have a tomtom bluetooth gps receiver that I used to use with my xda-ii for my satnav solution. I had a car charger that charged the xda and tomtom unit at once. I have now upgraded to the Exec and am hoping to find a similar car charger but couldnt find any on google/ebay - does anybody know of one that exists?
Thanks
Allan
Cannot be of help, but looking for the exact same solution. I had an iMate JAM and a cradle that charged that (mini-USB) and had an output for TomTom Bluetooth. If all else fails I could try taking apart the adapter because it has the correct output, just the Exec won't fit in it!
assuming the TOMTOM gps receiver uses a round 5V center positive connector to charge it ( which it almost certainly would do )
then check out my posts in this thread,
http://forum.xda-developers.com/viewtopic.php?t=29351
the cradle even comes with a wire just for charging BT GPS receivers
Ouch! Thats a little pricey!
I already have a mount that holds the unit, so I am just looking for a calbe charger solution. Anyone have any links?
Thanks
Allan
in that case I have seen a car lighter plug on ebay that has a USB socket in the back, it was on £3~£4 you could then use a regular sync and charge cable to charge it
o2 shops are now stocking the car charging lead... complete with natty o2 shaped blue indicator!
To get round the problem of daisy chaining mounts and receivers, I got a great car charger - dual usb adapter from eBay (I searched for "dual usb car") which gives you 2 usb sockets for about £8 all in. Having bought this though, I'm thinking of installing a spare cigarette lighter socket behind the dash to power it from and cut down on cables in the cabin...
Funnily enough, the many Sync and charge cables for the Sony PSP would be able to simultaneously charge both a Jasjar and a bluetooth GPS unit
here is an example

Universal charger- special
The Universal as well as the Typhoon, Wizard etc. need special wiring for the mini USB. when connecting to the computer the the driver is activating the proper pins in the Mini USB socket and you can see the "charge" light on. However when connecting to a USB Poer Supply, pins need to be manipulated (some to ground or perhaps to Vcc). I'v looked into this issue many times (searching in the Internet) and could not find a proper wiring diagram. although I know for sure that they are exist as there are some Car working chargers offered for Universal / Typhoon.
In any case refering to this thread, a car charger that works for Jam/XDA2Mini most probably will not work for the Jasjar/Universal unless i is apecified as a Universal car charger.
If any of the memebers has come a cross a wiring diagram for Typhoon / Universal charging scheme it is appreciated if you could provide details.. as many of us would like to build their own car charging units.

Dude, what are you talking about !! I use the sync lead from my kodak camera to charge my JJ from my laptop it works fine but is slow (my laptop hasnt got much umph) and the same goes for the PSP power lead I mentioned earlier, I use that in the car with my cradle that happens to have USB sockets in it, (pictured in another thread)
It seems that either your usb lead has the proper connection to fit the requirements of the JJ or I am doing something wrong that I am not aware of.
Here is the test: Just take a Powered USB Hub, connect XDA1, XDA2, XDA Mini, XDA2S (all the models that I could test right now) and It seems that the Powered USB Hub can charge these devices.
Now connect the JJ (I suggest with a traditional USB syc cable that comes with either ..) and NADA I got no indication for charging .. than connect the HUB to the your computer which has the ASYNC installed and you see that immidiatly the JJ is being charged. Both feeding measured at 5.15V.
The Typhoon behaves the same for me as well.
Further more, I have few USB chargers (other than the one equipped with the JJ) which is in fact a PS with a USB port . The result of connecting the PS through the traditional sync cable is "No Charging".
The same applied to many Car USB charger that I'v tried.
Perhaps your Kodak sync cable is special (in fact I am looking for the schematic diagram of a cable like this)?.
I tried (just now again) also with Dopod 828 and it seem the same (no charging unless it is connected to the computer).
Please double check your charger cable and try th sync cable that comes with the JJ.
I dont see why kodak would have used a special sync lead, because on the kodaks it is used for data only (power comes in via a diffrent connector) when I get a chance I will buzz out the cable for you !!!
PS I think you shold plug it in and wait, mine starts charging instantaneously when used with the mains adaptor which has 1 Amp of current available, but takes a min or two to start charging when I am using my laptop/in car charger, both of which only have 500mA available.
Car Charge
From reading other threads, Pin 4 in the Mini USB is shorted to ground and that's probably turn on charging ..
I suggest that you read threads about the power charge / car charge in other forums... here is an example I took and although it talks about the Typhoon it is relevant to JJ as well and it suggest to connect pin 4 and 5 to ground. I can't have a good explanation why your JJ starts to charge after 2 monutes. I suspect that it has nothing to do with the current that can b drawn from the PS.

Here's what I've found on modaco.com forums, posted by richwookie on Oct.4 2004:
QUOTE >>>
...I've hacked open my C500 mains charger (quick, where's the superglue), and sure enough there are only 2 wires leaving the box to the mini USB cable, GND (black wire) and VO (white wire). However, after very careful probing, with a very tiny probe no less, I've established that the GND wire is connected to both pins 4 and 5 of the mini USB connector.
Now usually pin 4 would be not connected to anything as pin 5 is normally GND. So next I probed the C500 data cable to see if pins 4 and five of the mini USB were connected together. They weren't of course.
So what does all this mean?
Well, from what I've discovered I conclude that the C500 will only charge if:
1) There is data on the line (even if it isn't saying anything :wink: )
OR
2) Pin 4 of the mini USB plug is grounded.
So what's the solution to making the generic car chargers work?
Do nothing to the car charger. Mod the data cable so that pin 4 at the 'mini' end is connected to ground.
This IS all speculation and I suspect that it is easier said than done. I haven't yet hacked open my data cable, but I expect there are only four wires in it, and the only way to ground pin 4 (mini end) is to somehow bridge them at the connector. I think that is beyond my soldering skills (have you seen the size of the contacts on the plug?!) but I may give it a go anyway.
Anyone else want to try? Let us know here.

... and the 2 hours later:

Posted from my SmartPhone while it is charging in my car using a 1.49 cigarette lighter USB adaptor and my newly modded C500 data cable!
I'll let you know if it still works as a data cable when I get home. ;-)
....
Modded cable doesn't work for data now.
When I connect it to the PC it just charges. I suspect that when the phone is in 'charge from adaptor mode' it inhibits the data lines.
<<< UNQUOTE
Well, I guess it's simpler to mod a USB cable, than either carry around a charger, or install Activesync everywhere.
With all this chat about modifying pins etc call me naieve but why not just buy a dedicated charger from expansys or an o2 store ? both cost between £10 - £15
:shock:
Just an observation I have made... I have an O2 EXEC, and charge it quite happily (sort of) with the Standard USB Synch cable and a Car Lighter Socket USB thingy.
The only thing is... It will NOT charge if the EXEC is on (screen lit up) when the USB lead is connected or power connected. Switch the device off, connect the lead, and the charging light comes on.
I find the same when I connect it to the computer with the Synch lead too. It won't connect to ActiveSync or Charge if the EXEC is on when connected.
Hope this helps.
Is there any way to connect the Royaltek Saphire GPS (http://www.royaltek.com/index.php/content/view/20/30/) to the Universal? It has a XDA II cable connector, where can i get a Universal adapter or connector? :roll:
Thanx
I don't believe it's possible to use any cabled GPS recievers with the Universal.
It may be possible by using a third party mount for example.
http://www.pdamods.com/proddetail.asp?prod=A111U2CRIJASMNT
Yes, i think that should work, something like this http://www.keyspan.com/products/usb/usa19hs/ would probably work also but it has about the same price.
Thanx
no, that is an adapter for connecting devices with serial cables to a USB host port, which the Universal dosn't have.
Yes thats true. Btw is there any way to add a usb host to the Universal ? :?:
Does this exist? I'm about to purchase an HTC P3300 and I would like to use a car diagnostic software call "VagCheck". To use it, you need a cable to connect from the the PPC to the cars OBDII port. These cables only come for iPaq ppc connectors to OBDII, serial to OBDII, and USB to OBDII. These cables are expensive and I already have a serial to OBDII cable. So I'm looking for some kind of way to connect the cable to the P3300 via the mini USB connector but I know there will need to be some drivers involved.
Does anyone know if there's an adapter from mini USB to regular USB or Serial for PPC's with drivers?
BTW, there is a more expensive alternative. There's a bluetooth connector for the car that plugs into the OBDII and you can just connect via BT. But that is the most expensive set-up.
USB to serial
I guess you can use USB to serial converter, which is inexpensive.
Thread moved.
AFAIK the P3300 is USB client only, which means it can only be used as a client device to a PC. USB host capability is required to work with USB peripherals such as a USB to serial adapter.
So basically what you are trying to do won't work with the P3300 unfortunately.
The only way around this problem would be to get a bluetooth-serial module which would connect to the serial - OBDII unit and allow the P3300 to connect to it via bluetooth.
A bit silly I know, this is the result of most PDA manufacturers choosing not to equip their devices with USB host capability.
Antzzz et al,
You're right.. The current HTC range are all only USB Client.. So you can't connect an HID device, serial adaptor etc.. There IS rumoured to be a set of serial pins on the non-standard Mini-USB style connector on the D810 device range - however, we've never seen a cable that breaks out (or explains the RS232 pins)..
Does anyone have a full pinout of the extended connector??? This might be a project for further investigation.... ?
There are a few industrial RS232 to Bluetooth adaptors, such as :
http://store.pressdigital.com.au/industrial-bluetooth-serial-adaptor-rs232-p-5092.html
But they're expensive as a rule.. You may want to grab a Bluetooth OBDII interface.. (or another cheap PDA with RS232 like a cheap low-end iPAQ hx2490).
Let us know if you stumble across the RS232 pinout on the extended D810 connector.
