Condor+SYM/HP310?

[sisu1a]

Anyone out there get this to work properly? I've got my 310 and
computer on the same COM/baud... even got them to connect (COM
connection, not headset). Sorta got it to work with my 3.12
installation (accepted the NMEA stream from Condor and thought it was
in Slovenia...), but corrupted it in the process of trying to get
terrain to work and now I'm trying to get 4.01 to sync. I'm having
some specific problems...

1) although connected, on the same COM/baud, when I run Condor the 310
continues to receive real GPS signals and ignores the Condor feed
(didn't have this problem with 3.12. ...the Condor NMEA output is of
course enabled to the correct port as well)

2) can't use it in portrait mode due to the need to enter an access
code for bluetooth connection. Portrait puts the enter key off the
screen (with both SYM 3.12 and 4.01... it's an HP310 issue) so I can't
complete the bluetooth connection cycle unless in landscape. Changing
orientation req 310 hard reset which also resets bluetooth... Any
workarounds here?

pd. I'm gonna repost this in Condor and Naviter too... just thought
I'd check here as well.

Hi Paul,

The iPAQ 310 uses low voltage (3.3v) pseudo RS-232, so you'll need a cable
with an RS-232 voltage level converter. I sell them here:
http://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. 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.

and on the website

The cable includes an inline RS-232 voltage level converter which
converts the RS-232 standard signal levels to 3.3 volts as required by
the iPAQ 310.

Would this be a simple resistive divider or have you found something
much more complex is required?

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.

Hi,

Please see my notes below.

*** I have sold dozens of cables to glider pilots which make it possible
for the iPAQ 310 to talk over the serial port to soaring GPS units and
flight recorders. It works fine if you have the right cabling and baud rate
and select the correct com port (com 3 for the serial port cable
connection). It can't work with a 302 because the 302 only supports 4800
baud. But it works great with many other soaring instruments. A BlueTooth
connection should work fine too.

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

*** The iPAQ 310 needs 5V power for the main power. But the RS-232 (sort
of) serial connection is at 3.3 V rather than 5 or 12 V per the RS-232
standard. The Goddard cable does that conversion and also puts power or
ground connections to the right pins to put the iPAQ into "quick charge"
mode - which is necessary to allow it to draw enough current to keep up with
power usage.

Still having the problem with the screen rotation issue... I may just

Actually the 302 will support any baud rate you choose to set it to.
The problem is that it defaults to 4800 on next power up.

That reminds me I'm out of excuses for not getting on with my 302 auto
baud set dongle.
