My notebook (Compaq) is one of those new fangled ones that hasn't a standard serial port.

So, I done-bought-me one of them USB/serial adapters that is manufactured by Belkin.

The thing was $80 so I really didn't think I'd have any problems until the credit card bill arrived, but my Venture is not being detected through Street Atlas 9.0.

Both the GPS and software are common enough that it must be something physical. I've tried downloading the latest drivers for the USB adapter (Win XP)

Windows claims the adapter is using COM4, but setting things in SA9.0 toward that end doesn't seem to help.

Have Any of you actually had any success with this sort of setup?

I'm going to try EasyGPS and see if that sees anything, but I will be genuinely surprised if that works.

Hi Choberia. Welcome. Have you got the GPS settings in SA9 set to Garmin NMEA? I know that with both SA8 & SA Deluxe, I have to have the settings on Garmin/Garmin for my III Plus. But for my eTrex Vista, they have to be set at Garmin NMEA. I still can't figure what the settings have to be with my MAP76. Get the help files up in the right hand corner & go to GPS & get to third party receivers. Seems anything other than a DeLorme GPSR, you have to do some screwing around. I've also downloaded all info from the GPS into G7ToWin, saved info as SA8 file & then downloaded into Street Atlas Deluxe, Street Atlas 8 orTopo USA. Roundabout way to do it, but until I can get it all figured out, it'll do. I should really just stick with my Mapsource R&R  and Topo, but that would be far too easy,right? :0o Hope this helps. --Gimpy--

One problem might be that the USB/Serial adapter is configured to "virtual" COM4 and not Physical COM4. I have seen this in many cases and it is actually the standard method for IRDA devices in most versions of Windows.

Another possibility is that the I/O portion of SA9.0 may be hard coded to communicate only on a physical com port and therefor will not see the device connected via a USB port. This is something I deal with everyday with customers on certain printers when they are attempting to use a USB/Parallel adadpter.

I personally am amazed that the GPS manufactures have not yet started offering more in the way of USB as this is exactly the type of devices it was designed for.

Thanks for your help.

MapSource (Topo) isn't seeing the GPSr either.

I've uninstalled and reinstalled the drivers, and I'm wondering if this is indeed another item that can be laid at the feet of Xp?

Doubtful it is an XP issue.
Again I am basing this on daily tech support ecperience and would bet it is more the I/O driver function of the software being used.

perhaps a patch from the SW Mfg. ?

I should offer up some closure to this thread.

I never did get it to work in my apartment, never would see the device at all. So I brought everything to the park with my daughter, figuring I'd have plenty of time to futz with it as she went up and down the slide....

I'll be dag-gone if that thing didn't see the GPS and center the map SA9.0 on the park where I was sitting.

Thanks for your help everyone.

Just a thought if you encounter this problem in the future, ie no signal, no comms, If you have a simulate feature on your GPSr, it should output the appropriate NMEA signals without satelite lock.
