Default Condor+SYM/HP310?

The iPAQ 310 uses low voltage (3.3v) pseudo RS-232, so you'll need a cable
with an RS-232 voltage level converter. Â*I sell them hehttp://www..cumulus-soaring.com/goddard.htm#I310-PS5a-1

I'm also creating a Condor PC cable with 5V wall power plug that would make
it easy to connect a standard PDA cable or cradle to the PC. Â*I have ordered
one for testing.

Also, you need to use a baud rate of 9600 or higher because the iPAQ 310
can't use 4800 baud.


Thanks, although I'm a little confused. I don't need a charging
cable... I need it to serially communicate (at least receive) NMEA
with my computer while running Condor, which I thought can only happen
via bluetooth with a 310... am I missing something here? I do have it
set at 9600, COM 5 and since posting this have gotten it linked with
Condor again.

I needed to do a soft reset (or whatever it's called when you use the
device wizard to search, it exits/saves SYM and then I started it back
up without pushing the little button by the USB) once I established
the initial COM link. This allowed Condor's NMEA stream to override
the GPS signal being picked up by the antenna. Before this reset it
ignored the Condor feed and was telling me my target in Slovenia
required +732,360ft to reach

I have it plugged into a wall charger while I'm using it, although
it's a cheap knockoff that doesn't have the two 3.3v pins. I've heard
of folks (an electrical engineer I know for starters) hooking straight
5v to these pins without issues, but through trial and error (had a
bag of resistors in my hand) I found a 572MΩ resister chops 5v to 3..3
quite nicely if that's what you were asking Andy... sofar I haven't
run the batt down during trials so I haven't bothered bridging the
resisters to the 5v pin; plus I have the stock 12v charger and a power
supply if that is an issue...

Still having the problem with the screen rotation issue... I may just
be stuck with landscape here.
