IPAQ 1940 + Tom Tom 5 COM Port Problem

[JAG]

I'm in the process of trying to set up my IPAQ 1940 and GPS connection. The instructions say the GPS settings should be set to Baud Rate: 19200 and COM Port 1. I have an Arkon Powered GPS PDA Mount

I go into the software and select the following:

Show GPS Status-->

(Have to select one of the following:
Tom Tom Wireless GPS
Tom Tom Cable GPS
Other Bluetooth GPS
Other Cable NMEA GPS)

I select Other Cable NMEA GPS (I presume this is correct)
Select the Baud Rate of 19200

I then get a screen asking saying "GPS is connected to:
COM3
Bluetooth Serial Port...
Bluetooth Serial Port...
S2410 IRDA2410
S2410 COM0
Serial on USB

As you can see there isn't an option to select COM1. I have tried COM3 but doesn't work.

I have turned the Beam off under Settings-->Connections on the IPAQ. I have no idea how to check what COM Ports are being utilised on the IPAQ.

Anyone have any ideas how to get COM1 working?

Many thanks,

Ian

They can be a bit finicky even when you done all the right stuff.

Have you tried cold restarting the pda with and without the cradle attached? as it may get it to recognise the appropriate com port sometimes this sorts it out. For some curious reason a restart sometimes sorts it.
Presuming theres no menu for selecting an alternative com port within the Tom Tom menu Have you tried the Tom Tom cable gps option?

Its usually something minor with these things easily sorted if youre in the know if your still struggling try posting on Pocket GPS World usually get someone responding with a fix.

Yep, tried cold restarding without hte cradle attached and have tried the Tom Tom cable GPS, but there aren't any configurable options. It's as though something is tying up COM Port 1 but I don't know what.

Don't know if i've got this right ?
Take it your pda is connected to your cradle gps via wires ie it doesn't use the blue tooth?
If the Bluetooths on on the pda and hence it may be using the comm port causing a conflict and stopping it communicating with the gps
Appreciate you may have done this already but have you tried switching off the bluetooth on the pda,ie is it showing ON? and see if it frees up the right comm port ?just a thought.

Yep, you're right, the pda is connected to the cradle with integrated GPS via a USB to serial power/data cable. Bluetooth is switched off.

Having just spoken to a mate, COM Port 1 is the connection at the bottom of the pda, where the sync cable attaches to use Active Sync. Active Sync works fine on the so proves that the com port is ok. Could we be looking at a possible dodgy USB to serial power/data cable that has been supplied with the unit?

I'm assuming you are trying this outdoors in the car, rather than indoors?
Mine takes anything from 30 seconds to 1 minute to find the GPS connection.
Open TomTom, select the GPS connection option (page 3 of the Change Settings screen), and then configure - that will let you see all the steps - as you say, COM1 is the sync connection, and I used that on my wired receiver and it works fine. The ony problem i have is that the connector from the GPS untit to the power cable is a loose fit, so I had to tape it up to stop it falling apart.
Just a few things to look at - hope you sort it cos it's a bugger when you've got a new toy that won't play
Speak to you soon

Hi Martin,

I've stuck a detailed posting on the Expansys forums - http://www.expansys.com/forumthread.asp?code=105738&thread=188&man=HEWLE and hopefully might hear something today?

Yeah, out in the car in a fairly wide open space aswell and left if for about 20 minutes.

When setting up GPS I don't get the option anywhere to select COM1. If I can't get it sorted may have to look at further options. Possibility is a powered PDA mount with RJ12 connection, got any recommendations for a GPS/Bluetooth receiver that doesn't cost the earth?


Cheers,

Ian
