Greetings Folks,
I built up a serial cable (null modem) today using the info on this site. Have double checked my connections and wiring and am having no luck what so ever. Everytime I try to make a connection between the phone and the serial device (similar to a GPS) I get an "Error 55, Unable To Open Serial Port COM1".
Is there any kind of registery or other software adjustment that needs to be made to get the serial port to open on these units? I'm kind of beating my head against the wall on this one.
The connections I am using are as follows:
RTS (Pin 9) to CTS (Pin 7)
DCD (Pin 6) to DTR (Pin 11)
RX (Pin 10) to TX on serial device
TX (Pin 8) to RX on serial device
GND (Pin 16) to Serial data GND on device
Any help would be greatly appriciated.
Thanks in advance.

i´m trying to connect a rs232 gps in my XD2 ( rom 1.72). But as soo n as the pda receive data from the external serial port, the PDA "gets crazy" (dial application appears, there are some sounds, ....) it is like the pda thinks that an external keyboard with crazy data is attached. After a full reset, the same problem. I do not have an external keyborad or drivers , etc. I turn IR off, radio off, the same problem. The GPS application is able to receive data but the "dial application" always appears ...
OI´connecting only RX,TX and GND, as explained in the "connector" page in this web.
The fatc is that as soon as the serial port receive data, the pda gets "crazy".
Any idea?
solved !
I was using pin 2 for GND, but if I use other GND pin , work with no problem. Conclusion is that pin 2 is a reference not valid for rs232 port. Hope can help !
Hello Guru's,
I have a GSM BA with the latest SW upgrades & have not been able to make communication with my Garmin GPS III. I connect the BA & Garmin with 2 serial cables (one is a BA serial cable & the other is a Garmin Serial cable w/ car charger) with a gender changer between these 2 cables. I have tried the following with no luck:
- GPS is set to NMEA standard (4800 speed). It works fine & shows location data on it's screen.
- BA is on COM1 with 4800 speed. I tried all the ports including AUTO configuration.
- I tried Navio & Mapopolis as receiving SW on BA.
- I connected the GPS to computer & could see the data coming on a hyperterminal.
- 'Incoming Beams' is off on BA.
Any help getting me to make the GPS work with BA would be appreciated.
Thanks
A gender changer is not enough, you need a null modem adaptor between the 2 cables otherwise the serial connection is reversed and will not function.
Thanks a lot, I got a Null Modem adapter & it works like a charm
I have a Tomtom Bluetooth GPS I need to get GPS information from the XDA to connect to a APRS system. I need to get the following information from the serial port GPS Data Out, GPS Data In & GPS ground.
Has any one got any idea how i can get this information out of the Serial port. Any help appreciated...
Thanks Stuart
hi
It'll be hard.
It's impossible to achieve without special software (which I don't know about).
The software would have to receive GPS data from bluetooth com port (eg. com8) and channel it to software com port (for TomTom) and to hardware com port (bottom xda connector).
I assume You won't be able to write such program.
My suggestion is to get a second GPS recevier (cheapest serial GPS mouse) to serve your APRS (whatever it is )
Good luck.
Does anybody know how to 2 Bluetooth Serial ports on the XDAII ?
I am using Pocket Bluetooth Tools to give me a Bluetooth Serial Port. However I only get COM7 appear in the dropdown list when I bond a SPP Bluetooth device.
This has been fine for a couple of years as I only had a Serial Port Plug for plugging into equipment instead of using a Comm1 Cable and I run a VT100 Terminal Program.
However I have now got TomTom and have a Bluetooth GPS receiver. I am getting tired of having to delete one SPP device and then rebond the other to the only Com7 Port.
There must be a way of having 1 on Com7 and the other on another virtual serial port, but as I said earlier only Com7 appears on my XDA ?????????????
I cannot open COM1 on the Blue Angel
As far as I know this COM1 relates to the Pin headers RS232 connection.
I want to feed a GPS signal via this COM1 path.
Has anyone manage to make use of the COM1?? :?
Martin, go to Settings/ Connection tab IrDA and uncheck the "recieve all beams" check box, this ties up the serial port on the device, also if you use an external keyboard with the unit, or it has external keyboard software loaded open this application and switch the software from Keyboard to IrDA/ Serial - hope this gives you a clue - Mike
thanks this helped me too
Thanks
This sorted out my problem...TomTom is now alive and kicking
