Garmin 12 to XDA II: Tearing my hair out!!

[Stephan]

Hi there,

As the subject suggests, i'm having some trouble connecting my (slightly ancient I know) Garmin 12 to my XDA II pocket PC....

The Garmin 12 has the duel cigarette socket power / serial cable that terminates in an RS232 9 pin female serial cable that should be connected to a PC. This part works fine and i'm able to talk to a PC for a route mapping program or even to upload or download waypoints.

The XDA has a XDA type connector again to RS232 9 pin female serial that again connets fine to a PC and can sync.

The GPS is setup in NMEA/NMEA mode at 4800 baud and i've tried various settings on the NMEA type (182, 183 / v1.5, 183 / v2 etc) but i've never had to change it from 183 v2 on a PC. Something possibly worth nothing is that i'm running the unit on battery. Perhaps I should try again on power but I doubt this is the cause?

The trouble begins when I attempt to get them to talk. I presumed a null modem cable would be required as its two serial devices attempting to talk. I downloaded a demo copy of a program called GPS tuner for the PPC and tested the connection - nothing. I also purchased a copy of TomTom Navigator 5 and again nothing.

I found another website that suggested that the only connections the null modem connection needs is pin 3 to pin 2, pin 2 to pin 3 and pin 5 to pin 5 so I even tried chopping all other connections except these in desperation!! (its no big deal, I can solder it back up if necessary) but still nothing!

Short or purchasing another GPS reciever (which i'm loathe to do as i've just splashed out on the software and I have a perfectly good GPS already) does anyone have any thoughts?

Many thanks for reading this oversized post!

Stephan

You did not have to solder/desolder anything if you had a null modem adapter. Even if you did not there is a very simple temporily way to do it just to veify that is is working.
Use 3 stiff wires and connect the 2 cables like:
2>3
3>2
5>5
And then of course the IR beam setting is catching most people doing it for the first time as the setting is default and preventing anything from accessing the com port.
