Serial port of XDA

Hello, all,
we try to connect to the serial port of the XDA, but I cannot open the port COM1:
We have the proper connector, but I have no chance to open the port by software. What can be the reason, do I have to make something on the connectors (bridges ?).
Thanks a lot ...

i initially had this problem using windows xp. i fixed it by changing the settings of the resources (I/O Range and IRQ) COM1 uses in the device manager.
hope this helps.

Thanks, but I do NOT mean the serial port of any connected PC, I mean the serial port at the bottom of XDA.
I programmed it by embedded VC, on other devices this works, but the phone edition seems to disable the port. I can see COM1: in the registry, but it's not getting active.
I read, that I need a null-modem cable, but this also wasn't sucessfull. What should be inside the cable to communicate with any serial device outside the XDA?
Thanks

Make sure the IR port isn't grabbing COM1:
Start/Settings/Connections Tab/Beam
"Receive all incoming beams and select discoverable mode" should be left unchecked. In addition, close (via Settings/System Tab/Memory/Running Programs Tab/Stop) any driver software for accessories like keyboards that connect to the sync/charge port. Then you should be able to connect to COM1.
With respect to a Null Modem: You need to also hardwire some handshaking lines together, so don't abandon the null modem.

Hi,
thanks for the first replies. I already switched off the IrDA, and I can open the COM1: of XDA. Everything seems okay, but no data on TX...
I saw the connector layout on this site, but can (want) somebody to tell me the layout, if I want to do serial data-connection to an external device(not activesync)? I think, I need more hardwires than known by me....
I connected:
RTS (pin 9) with CTS (pin 7)
DCD (pin 6) with DTR (pin 11)
RX (pin 10)
TX (pin 8)
GND (pin 16)
What else can I do ????

I would attempt to connect DCD to the DTR of the computer at the other end, but am unsure whether this woud make a difference.
We experienced problems with the sreial port in older versions of the ROM. if I remember correctly, things didn't work in 3.00.xx. But I doubt you're using something that old.
Good luck...

Thanks,
but are there any other bridges/hardwires inside to do inside the connector to acivate the serial activity of the port ?

I also don't have a PC on the other side, it's a device, which has no handshaking ability...

You do need a null modem adapter. If you are using one, it may not be a proper one.
Or you can use a "serial/modem interface cable" you can get from www.pc-mobile.net in the XDA page.

Does anybody know how to access the hardware serial port (on Blue Angel)? I can use IR (COM1) and Bluetooth (COM4) to send/recieve data, but the bottom pins don't give any voltage. I've tried other ports (to COM9) but the device hangs unless it's COM2.
Here's the test app, select port on the left and then click 'Open Port'. When the port is open, the device is showing what is read at the port. You can click 'Salji' to start/stop sending dummy data via port or "Lista Portova" to list the available ports.

You have to deactivate IR to get Serial Port working, as thay use the same port!
(Settings/Connections/Beam/deactivate Receive all incoming beams )

I've tried that, when "Receive all incoming beams" is enabled - COM1 is invisible to the program and reports error, when disabled - the IR becomes COM1

Try the attached file by haicom.
Serial and USB crandle have different pin-out!
http://forum.xda-developers.com/wiki/index.php?title=Connectors
Serial should be Com2 and is usable when Com1/IR is disabled.

Thanks! I'll give it a try as soon as I find a way to disable IR (and find some time to play with it)

Pin layout GPS to XDA cable needed

L.S.
Can some body help me to the pinlayout for a cable that connects a Haicon GPS203e to a XDA.
I have the layout for the GPS and XDA connector and can figure out the RX TX GND and V+ myself.
What i am looking for is special connections for DCD, CTS, RTS and DTR. Do I need to connect them to e.g. eachother or gound to activate transmission??

I do not know about the Haicom but you should not need to connect these.
Most GPS transmit constant NMEA signal while it is turned on (power on and with satellite lock). The biggest problem for you is how to power the GPS.

Thanks for your reply,
Power should not be an issue, i will connect to the XDA carkit which has a regulated supply for the XDA that should work for the GPS.
What I have seen in the past is that some of the additional RS-232 control lines have to be connected either to each other or ground to activate communication. I am wondering if somebody has a layout of the XDA cable for Haicom (three-way cable : lighterplug/gps/xda)
Francois

You do NOT need to connect or short any of the other lines to make this work. I've done the same with a Pharos GPS and custom car kit, and only connected the data and ground lines.

Tom Tom and Haicon GPS need extra line!
Today I tried to hook up the GPS to the XDA carkit as suggested (only GND TX and RX) but Tom Tom will generate an error saying it cannot connect to com1:
I noticed a difference in behaviour when using the orginal cable: when connecting the XDA it opens active sync immediatly.
Did some reverse engineering and found you need to connect the DCD to +5 volts. After that it works as designed.
Got the XDA carkit running with a Haicon GPS!

Newbie help
i would like to use my GPS Heicom 203 that i have purchaased for iPAQ 3870, can you help me with the connections to avoid damages in my XDA ? I am a newbie of this kind of works, so i wouldn't make disasters.
TIA

Reverse engineered XDA Carkit
Not sure is this is what you're looking for but a guy from the Netherlands did some reverse enginering on the XDA carkit...
Check out http://www.pocketpc-club.nl/content.php?id=1275
RTS - Purple
DCD - Red
DTR - Blue
CTS - Yellow
RXD - Green
TXD - Orange
GND - Black
+5.5 V - Brown
Cheers...
Mike

Some additional info from the guy in the Netherlands.
L.S.
It´s funny to see that I have originally started this topic and now are beeing refered back to my own information!!
If you need some additional info have a look at www.vanhemert.biz or drop me a mail.
Francois

connect GPS to XDA
Do you have connected Heicon GPS to XDA ? If so, can you post me the pinout connection to use Heicon with XDA ? Many thanks in advance.
P.S. Sorry, i don't want to make disasters.
Thanks again
ConteMax

ConteMax I have received your message to my e-mail adres last week and have sent you a reply to your questions. If you need the layout, please have a look at the following website: http://www.vanhemert.biz/Car_Kit_GPS_Connection.htm This page describes how to connect a Haicon 203e GPS mouse to the O2 carkit.
If you do not have a carkit, have a look at the connector page at : http://www.xda-developers.com/connectors/ it describes the layout of the XDA connector.
The only thing you have to do is connect the GND, RX, TX, VCC and DCD line to get the thing up and running.

XDA/MDA Connector GPS
You need information about connector GPS.Please send me an e-mail
([email protected]) and i send you a Fax with original colors of cables.
You can use all GPS-Mouse with PS2 and serial-Connector.

Can some body help me to the pinlayout for a cable that connects a GPS ( rs232 ) receiver to a XDA.
I have the layout for the GPS and XDA
We need to powered GPS and XDA ( GND and +5V ) and after :
GPS TX must be connected on pin 10 ( RX RS232 ) XDA connector
GPS RX must be connected on pin 8 ( RX RS232 ) XDA connector
Is it right ?
JLuc

I would be interested to know if the new XDA IIs has the same pinout as the earlier XDA's.
It's all in the cause fo getting the XDA IIs to accept a serial connection from my garmin GPS V.
Currently i get an error indicating COM 1 is unavailable
Any other suggestions welcome

Guest, check under setting/connections, make sure that beams is unchecked, this will release com 1, also if you have an external keyboard driver loaded you will need to deactivate this also.

GPS for the PocketPC Phone Edition

I want to connect my Garmin Geko GPS to my PocketPC Phone Edition. It seems that regardless of what I do there's no receiving any data. It's only a three wire interface, so how hard can it be? The Geko puts out a NMEA format at 4800 baud, that's what the Pocket Streets application wants.
Q1: The Pocket Streets GPS Configuration screen shows that I have available COM2, COM3, COM8 and COM9. I thought I saw a COM1 in there before, but right now this is the list I see. Which COM port is wired to the connector?
Q2: I've heard that I may need to disable IR, a keyboard driver, or ??? to get this to accept input. Help out a newbie and tell me exactly how to turn off these features (it's not obvious to me).
Q3: I've loaded ZTerm on the PocketPC Phone Edition and used a serial cable to type back and forth with Hyperterminal on my XP system. This even down to 4800 baud. So I know it's possible to exchange data via serial port. Since it's only a three wire interface from the GPS, I've connected the Tx,Rx, and Gnd to the phone, but no data to the application or to ZTerm. I've tried tying the CTS, RTS and DSR lines together on the phone and made sure there was no handshaking, but still no data to ZTerm (or Pocket Streets). Wuzzup with this?
Thanks in advance! Bewildered with some cool toys :?

Ok I had a similar problem with TomTom.
Ok to disable IR go to Start/Settings the do to the connections.
Select Beam there should be a tick box labelled Receive all incoming beams.
Then go to pocket streets start it up and you should be able to select com1
Hope this helps, Just for information if the received all incoming beams is selected then it acts as your comm1, until this is de-selected you cant talk use the seial port on your bottom connecter.

Bluetooth problems from a newbie

I have recently "upgraded" from xdaII to xdaIIs and I'm having a few problems. I have upgraded the BT stack to 3500 but I still can seem to connect to my tomtom gps. Device sees it but tomtom 3 cant. I'm completely confused by the connection wizard- none of the profiles seems to fit gps. I also dont seem to be able to send or receive files from my old xdaII. What am I doing wrong?
I'm also a little confused about roms. Do I need to upgrade my rom? Is there a simple way avoiding anything too technical (I've read about "country codes" and other wierd stuff). My current config is:
ROM: 1.12.62
Radio: 1.02.00
Protocol: 1337.32
ExtROM: 1.12.178
Could someone please help! I only have a few days to decide if I want to keep it or stick with my xdaII...

Gps's use the serial profile to transmit the data over - its like a virtual serial connection - so you need to tell tomtom to look on a com port AFAIK,.
For eample in my Tomtom list of connections there is one called 'BT on Com6, ' which is the bluetooth comport on my unit.
But there are also listed more com ports...
Com5
Com4
Bluetooth Serial port Com7
The XDA only actually has 1 com port (com1) so any other are virtual ports created by various software, you just need to find out which one is the one for the GPS...

So in "tomtom gps v3.07" I go to the gps tab and by default its set to infrared port. I change to "BT on com6" and click OK. When I restart the program it always resets to "infrared port" even if I try a different port. Really am stuck- never had any problems with my xdaII- just put in BT port and it picked it up automatically...

The problem is it's not always the same com port for different devices - firstly does your unit have the widcoom stack version of are you on the microsoft stack..
Whichever you have you need to find where the BT com port is configured..
On my widcomm i go to 'bluetooth setting' ; 'services' ; "serial port'; 'advanced'
in there it says...
inbound com port : 6
outbound com port : 7
so the incoming com port on my bluetooth is 6 hence the 'BT com port on 6' listed in my tomtom gps.
so you need to find your BLuetooth com port and find out which com port number it is set to. Not sure as to why tomtom gps does not save your settings, the only thing I can think of is becuase it never gets a valid signal from the comport select, and does not save the change unless it does.
Also: I assume the gps unti has a pairing with your XDA unit?

So does the widcom stack work on the xdaIIs? If so where can get it?

Sorry: I cannot be certiain the widcomm works with the IIs, but is can be downloaded from this site if you are willling to try, just do a search oin widcoom, and you will find a lot of entries...
For the MS BT stack; look under start, settings,System tab. There is a icon labeleld Bluetooth settings in there you can see/set the com ports for the bluetooth link. they also need to be enabled witch a check box before they will work...

So on "bluetooth seetings" serial port/advanced I have inbound COM port 5 and Outbound COM port 6. Below it says "Default device for outgoing serial connections: TomTom Wireless GPS. Display the device selection screen the next time an outgoing serial connection is attempted" next to a ticked box. I have tried bt com 5 and 6 in the gps settings and it wont save or recognise either. I can, however, pair and connect to the device in my BT manager but Tomtom doesnt recognise it...

Hmmm - all sound ok to me but I currently use a wired GPS, so I have not actually done it. I'm afraid I'm as stuk as you are now...

Sorry bro- I have sorted this now. Thanks...

For me, I just selected Comm 5 from the GPS status drop down and it works like magic!

GPS Reveiver issues

Hi All
Thanks for creating such a great site - its become a total lifeline for me with my XDA.
I need some help on setting up my sat nav. I have Tom Tom 5 put on a 1gig SD card, and I'm using a fortuna GPS U2 receiver which has a USB connector one end, a connector to the PDA in the middle and a PS2 connector to the GPS antenna on the other end.
Been trying to configure it in Tom Tom, I know I need to set the baud rate to 4800 as per fortuna's website, but does anyone know what I should tell the system the GPS is connected to? I have a number of options:
Com9
Serial Cable on Com 1
Serial on USB
Infared Port
Serial cable on Com 2.
I've sat out in the car an played around but can't get it to pick up a signal and I'm ondering whether its me setting it up wrong that isn't helping.
Please...can anyone help me?
Simon

try this
on your phone go into settings then connections then beam and untick beam then in tomtom go into change preferences then show gps status then into configure select other gps receiver then select com1 try this if you search wallaby forum there is lots of post on this

Thanks Jay - after lots of swearing and soldering I have now reassigned the pins and so far all seems well. The only thing I'm not getting at the moment is audio out of the speaker - however I do get audio when the headset is connected. Does anyone have any ideas?

audio
turn the audio on in tomtom its in the settings
