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!

Hello,
on a MDA III the synchronisation over a serial RS232 cable works fine
(although T-Mobile doesn't sell such a cable). Some software which I
develop for PDAs which uses the RS232 port there for communication
with external electronic hardware works fine on PDas but not on the MDA
III. It always crashes when I try to open the port (COM1).
Some installed device manager tool (a view only tool) seems to confiorm
that COM1 is the right one. It is named like this: "Serial cable on COM1".
What's wrong here? Active Sync has been closed before starting my
application. SOmebody somewhere mentioned that the keyboard could
block the com-port. Is this true? And if yes, how can ActiveSync then use
it?
Greetings

No, it's not true. The port is open by an
IR daemon listening for the connection,
and serial and IR share the same UART.
Uncheck the button in the settings, and
everything will work.
Everybody who has a RS232 GPS receiver
had the same problem.
Hi!
Is it posible to use the phone as a USB GPS when connected to a computer?

Hi Paalkr,
I don't know for USB link, but there is a freeware which transform the PPC into a BT GPS : http://www.pocketpcfreeware.com/en/index.php?soft=1488
Hi
Thanks for the tip... Maybe GPSgate can be used to redirect GPS signals (NMEA) to the USB port.

Next week I will get my xda orbit and I should like to know, how to establish a connection with a serial device . Is there a converter to the usb conector or a possibility to manage it over Bluetooth or IR?
Is the orbit a usb host or only a client? Maybe there are adapters for a host device.
Thank you

Hi all,
This forum being the greatest about HTC, I think you guys will have the answer :
I would like to use my TyTN to connect to the console of a router (using serial connection) :
1. Does anyone know where I could find a miniUSB-DB9 adapter ?
2. Will there be a driver for serial port, or is it natively managed with COM ?
Such cables exist but for PC, but not miniUSB and with a Windows driver, no info about the same thing for PocketPC.
Anyone knows ?
Thanks

Understood the problem..
Hi all,
AFAI understood I cannot find a solution due to the lack of USB Host support in the TyTN. I still wonder if the port can be used in direct low level serial mode as you see in bootloader. Could WinMobile use it ?
Another way would be to have a device that would be usb host, putting the phone into slave mode, but maybe I dream...
Thanks for any reply..
there is a bluetooth to serial adaptor which has been reported to work with the tytn.
COM1
Hi,
After much googleing there's still hope. Windows Mobile presents a COM port : 'COM1 via cable' and in the specs of the TyTN there is RS232 communication.
I still cannot figure out if the miniUSB connector pins could be simply mapped to the corresponding RS232 signals. Probably not
Anyway I flashed the XDA-Live wm6 ROM and it's great ! the battery seem to last longer (still 70% after 2 days!)
Thanks to the xda-dev community
Hi Gues,
could that work, to run a qteck 9090 as WeatherStation Interface between Internet (over internal SIM) and a WeatherStation ?
wview project? oder WeatherDisplay?
Is the USB Interface Docking able to provide Interface for other resources than an PC?

starting with the usb: no.
the blueangel has no chance of being a usb host, it is a client like a flash drive or an external hard disk, which means, since there can be no client-client connections there, you cannot attach any other hardware to the blueangel for it to use.
i don't know exactly what you have in mind there, since the first sentence is hard to understand, but you can use the BA as a remote client to connect to a host system over wireless communications like gprs, wlan or bluetooth, and control or oversee the host and manage it.
if, on the other hand, you were planning to use the BA as a "thin client" to connect a weatherstation directly to, to send you the relevant data, it would probably not work, because of the usb host issue.
