Data from ports 7879 and 30003

[gleff]

Ahhh.. that must be why.. I am running both, but for the programming purposes I was using V2 for the live data.

Pages 83-84 of the manual has some detail on the port 7879 output.  Probably the easiest to use, since it's in XML format.  Here's the example from page 84 of the manual:

<MODESMESSAGE>
<DATETIME>20070622141943</DATETIME>
<MODES>400F2B</MODES>
 ....
<LONGITUDE>-31.5789</LONGITUDE>
</MODESMESSAGE>

Use any standard XML parsing addins for your favourite coding language - eg the System.Xml namespace in vb.net.

If you want to play with this bloated format and convert to say .CSV or many others, there is a freeware program called GPSBabel.

Might be worth looking at.  It's aimed at GPSr users and can also convert to .KML for those interested.  Also has a list.

Could someone clarify or restate what the difference is between port 7879 and port 30003 data?   Is it necessary to monitor both?

Thanks

One port is ASCII comma separated, the other is XML.  Pick one, you don't need both.

Thanks.  I'll check both and see which suits me best.
