Hi All!
I have made a cable to connect the MDA III to my Royaltek RGM 2000 GPS device.
It works great but I don't understand one thing:
The documentation on this site says that MDAIII has rs232 interface (+-12V),
the documenation of the RGM 2000 says it only drives a TTL serial port.
I connected both device directly without a MAXIM IC.
How can that work?
Now I try to connect the GPS device to my PC over a MAXIM TTL to RS232 converter and I get only trash on my PC terminal.
Should I also connect the GPS device directly to serial port of my PC?
Please help!
I don't want the crash my GPS device!
Hi,
is it possible to use my MDA III, which is connected to pc over usb, as a bluetooth adapter in order to connect other devices to my computer?
Thanks in advance,
Paschulke507
Everything depends, what do you expect from this "combination". If you need full support for all BT features (direct access to BT stack like on the PC) - you can forget it. Just buy a chepest dongle for ~$10.
I actually want to do stuff like connecting a mobile phone to my computer and transferring small java games. Wouldn't such a combination over BA be enough to fulfill this purpose? I don't expect a fast connection or covering big distances.
You cannot do it directly.
Pair the phone with the BA, send the files to your BA and then beam the files to the phone. If it can accept beamed files, it should work (Nokias might refuse to start juch apps).
But the original cable for the phone is much better choice.
Ok, I'll try it this way. Thanks for your answers.
Hello everybody
I would like to connect my HTC TyTn II to a device which is using a RS232 for a serial connection. The software I need is running under Windows Mobile 6.1. So what I need is a device to "convert" the USB into a RS232. For PC such things are can be easily bought but I have not yet found something similar for Windows Mobile 6.1 and MiniUSB.
Have I overlooked something (maybe it was to obvious) or do those device really not exist ?
Can you guys help ?
Thanks
Michael
Hm, I believe you can do COM connections over bluetooth (I believe the phone simulates a COM port over bluetooth). You might want to look for a Bluetooth to COM adaptor (don't know whether this exists, though).
even if you found a converter and one could just use one of the many rs232 to normal usb dongles and then a usb to miniusb converter
but it would never work
because to use those conveters the device is required to support usbHost which HTC TyTn II don't
got the unit without the cradle , and usb cable, i managed to make a usb cable from a lg connector and it work well.
the problems : igo8 does not find the internal gps module and i cannot connect to wi-fi networks, i find thye networks but cannot connect.
i try to update to wm6 or reflash wm5 but the pc installer won't work without external power. the phone charges trough usb , but the application ask's for wall adapter plugged in. I tried to trick the phone by making him see a charger using the connector circuit found on pinouts.ru bun doesn't doo the trick .
does someone have a cradle internal schematic , or there is a workaround on updating the pda ? thank's in advance
please help me
nobody has any ideea on how to workaround that protection ? so i could instal wm 6 without the wall charger ?
Dear All,
I would like to share my experience in this TMC project.
Recently I bought a Chinese GPS 100 unit to connect to my JVC KD AVX40
This has an av out in 320x240 and JVC has an AV in.
You can control the unit via touchpad.
It works correctly to my unit so I decided to get a TMC for this product.
This unit has One USB port which is in Host mode.
So Put a normal USB hub on it and it worked well with Pendrive and External Mouse
Next step, I got a FTDI USB to Rs232 device.
It has FTDI 232BM chip for UART connection it's very important to use chip like this , because of the windows ce driver
I've opened it and I removed chip called SP213EHCA.
In every RS232 there are 2 chips on the board. One is for USB to UART , and the second is for Uart To Rs232.
Because the every TMC receiver uses TTL communication which is working on 3.3v I need to "convert" the unit to USB to UART TTL only.
Obviously you can build a small circuit for this communication, but for myself it was easier to use this solution.
After I removed the Rs232 chip.
Datasheet Page 5 for picture of the pin outs.
You can download it from the FTDI website
The Tmc Receiver pin out is :
Pin definition:
Pin1 Vcc: 5V +- 10%
Pin2 TX: 3.3V TTL level, TMC data output.
Pin3 RX: 3.3V TTL level, receive commands.
Pin4 GND <-- It's not ground It's 5V !!!
Pin5 GND (for mini-USB only)
I soldered a mini USB mother type connector to the chip legs:
PIN2 goes to chip leg 24
PIN3 goes to chip leg 25
PIN5 goes to chip leg 17
So after this I connected the Royaltek TMC unit to my "hacked Rs232" board.
I put the "hacked rs232" to hub and I used a USB mini usb cable for power the tmc unit, so I connect the cable to hub and after that to the tmc.
After this I used this driver for windows ce 5.0
You can download it from the ftdi web site
I have to use mortscript which copy a self made reg file to the registry and copy the ftdi dll to /windows/ folder
Reg:
REGEDIT4
[HKEY_LOCAL_MACHINE\Drivers\USB\LoadClients\1027_24577]
[HKEY_LOCAL_MACHINE\Drivers\USB\LoadClients\1027_24577\Default]

[HKEY_LOCAL_MACHINE\Drivers\USB\LoadClients\Default\Default\255]
[HKEY_LOCAL_MACHINE\Drivers\USB\LoadClients\Default\Default\255\FTDI_DEVICE]
"DLL"="ftdi_ser"
[HKEY_LOCAL_MACHINE\Drivers\USB\ClientDrivers\FTDI_DEVICE]

"InitialIndex"=dword:00000001 <--- This is for which com port to use 1...9
"Dll"="ftdi_ser"

"Version"="1.0.2.11"
"ActiveSyncSetting"=dword:0003e880
"LatencyTimer"=dword:00000010
"DeviceArrayIndex"=dword:00000000
This reg file is directly uses COM PORT 1 (It was free in my device )
After this I created a very small circuit which holds the usb power for 20sec
parallely my reg and driver is installing in this time.
When I reached 20sec My Hive based Windows Registry will recognize the FTDI device and there are no pop up meassegas appear ....
IGO recognized the TMC device hardware
The reason I write this how to , because I read so many forums ,and web pages to find a solution for this , but i didn't find anything.
GNS is providing a TMC receiver for CAR PC but with a prolific based USB to UART chip, and the ARM based cpu is not understanding the driver
Ough I forget the tmc receiver what used:
Royaltek RTA-3000
Have a nince day I hope that I could help to someone

I got the same JVC stereo, how can I unlock for multizone DVD? Thank!
If i understand it correctly that you mean, you want to unlock the dvd region limitation.
I didn't unlocked it, but the main problem, that the unlock lock status is came from the dvd FW, which is not possible to reach it, via this unit. I searched for the web, and JVC also, for some FW update. There isn't any. So from my side i say it's not possible in easy way.
I have tested this solution and since half year aho its working fine under -20 to +50 so it is a solution.
Sent from my GT-I9000 using XDA App
Compatibility
Also tested with FT2232H
This soultion is working , only bug that because of the dual uart the windows device pop up a notification for the second uart driver.
Also working.
Not working with Moxa chip.
Not working with Prolific PL-2303. ( Because the driver for the chip is not going to get open com port in wince 5 :S )
It seems that the only solution is the FTDI chip.
I've made a test with bluepanter and Wayteq and a very old Blaupunkt.
Solution is worked when I changed the usb mode to Host in wince.
It's seems for the blepanter and the wayteq it make not so much sense bacuse you could buy their original accessories.
For the blaupunkt is okay.
Also this could be okay for the 1-2 din chinese gps. Needs to be tested.
Reception improving
I had issue with the tmc reception.
So the solution is make a fm Y cable, and share the outdoor antenna to the head unit and to the tmc receiver.
After the installation, I realised that the reception was not so good, because I miss calculated with the phantom power to my roof antenna, after the phantom power installation everything went fine.
I got reception where I never had it before. TMC news downloading time improved as well.
Take care with the phantom power because it could kill the TMC receiver, use only one way adapter !
hi,
many many thanks for you thread...i had some questions...
i have bought an Dynavin DVN-MC2000 and this unit is without TMC but it have an GPS-In Mother-Usb cable...i think this goes directly to the wince5.0 system.
Where did you buy your RT-3000 and do you have the complete name of the FTDI Modul?!
Maybe we can develop a solution together i could make fotos from my open DVN-MC2000 if it helps
Maybe a ohoto would be great.
I bought the tmc unit in hungary in an avarage shop.
About ftdi i had one in my work desk. But it doesnt matter the meaing is it should any type which is supporting from the wince ftdi driver side. See ftdi web.

Hello all!!
I've been reading the post and I have to congratulate you, very interesting!
If you do not mind I'll use this thread because I want to ask you a question, I haven´t found any response in any expert forum.
I have a problem with my car radio. It is a chenese radio with GPS and TMC integrated.
From the beginning the TMC worked correctly but It had problems with the GPS. It didn´t work properly (may be the driver was wrong or it was bad installed on the WIN CE5). The provider din´t give me a solution and I found a forum in France. There someone sent me an European WIN CE 5 ROM with the GPS installed a working properly. The problem is that this guy didnt have any ROM with the TMC driver integrated and now I dont have it installed.
My actual state is: WIN CE + GPS HW (installed and working) + TMC HW (not insalled)
My question is:
How could I install the TMC in my radio WIN CE5? The HW exists but my WIN CE 5 does not have the drivers and of course the IGO can not find it.
Thank you very much!
pd: sorry about my english!!!

From the first i need to know what kind of tmc chip do you have. Royaltek/GNS and after that we can get closer to the problem. Qhit the upper sokution you can put in the driver if we will figure out the chip manufacturel.
Sent from my GT-I9000
I am sure that the integrated chip is GNS tipe.
The only thing that can hapen if we install a wrong driver is that it would not work, wouldnt it?
But the other things would work good...
thank you!

Generally yes.
But first. You will need to do some test. I will post it later. Because right now in this days i have a lot to do. I wont forget your problem so i will post it here what to check first to start your problem solving....

I found something maybe from your IGO8 folder is missing one file called gpstmc.dll
Check this forum
http://www.mobilepassion.org/viewtopic.php?t=2355
I will check it.
Anyway I think that I need the driver for TMC receiver. I have the HW but it is not installed. Do you know were could I find TMC drivers for Win CE 5? with them the problem would be solved-install and the IGO would take it automatically (I had it installed the first time, but the GPS didnt work).
