Hi,

Like everyone else, we were told that the iPAQ 310 did not have a serial
port. *But then someone found a double-secret serial port on the USB
connector. *The hardware is there. *It took us a long time to get it to work
though because it has some idiosyncrasies. *It requires an inline RS-232
voltage level converter and it works only at 9600 baud or higher. *. *That
is a bummer because it therefore doesn't work with a Cambridge 302 or LX
Colibri. *But it does work with EW microRecorders and LX products that work
at 9600 or 19200 baud. *Below are link to 2 new cables for use with the 310.
I have them in stock.

I also have a new cable for use with the Bendix King AV8OR. *I have tested
it with the standard (smaller) AV8OR, but not the new large AV8OR. *The good
news is the AV8OR works at 4800 baud and has the brightest display I have
seen in a PDA/PNA.

Hi

Does anyone have any info on what serial port is connected to the USB on
an
iPAQ 310/312.
I am trying to help setup one with XCsoar and feed in Flarm data as well.
I
have the Flarm data at the correct voltage levels but I can't work out
what
serial port the iPAQ thinks is there.

Ah a trick question? The iPAQ 310 does not have a serial port. It is
USB only device.

You will likely want to use a serial over bluetooth connection to feed
it data. Many pilots are using the K6-Bt bluetooth adapter with the
310.

Thanks guys particularly Paul and Andrej.

Anyone played with these?

Yes. I have an Aircable Mini and was able to make it pair and talk
successfully to the HP310/314 from my PC GPS simulator.

Unfortunately when I hooked it up in the glider to my LX160 it would not
talk to that properly so the HP got gobbledegook.

Have put it on the back burner as a winter project.

BTW I am very interested in the serial port stuff as this would definately
be a better way to go for a permanent installation.

Can anyone point me at a document that describes the port, specifications,
and / or functionality?

Looking at the fora it looks as though the problem is that the aircable
mini uses the same baud rate for serial and bluetooth ports. Therefore as
the LX transmits at 4800 baud the bluetooth goes at 4800 baud which the
HP3xx interprets as gobbledegook.

SNAFU!

Still looking for a cable solution? or a Baud rate converter?

This one is more programmable...

Google bluetooth serial adatper there are at least 10 types out
there....

Looks the same problem...same baud rate in and out.

The following would solve the problem:

http://serialgadget.com/index.php

You can use it to take the 4800 baud signal from the slow devices and
feed it out at 9600 or 19200 etc. Not the cheapest little gadget but
does the job.

The spec on the web says it requires 5V but a friend of mine has one
which they made up for him which takes 8-16V as input. He uses it in his
glider to upscale a Colibri output from 4800 to 19200 to feed to his
Ipaq so he can switch between the Colibri and Flarm NMEA streams as the
Flarm only outputs the extra flarm data at 19200 or higher.

This one is configurable $99 usd's
Anyone tried this one?

Same problem I am afraid, one baud rate for in and out, but in this case
minimum 9600 so wont talk to the Garmin or LX that I have in the glider.
Good try. Serial cable still preferred if someone knows the spec.

On the HP31x, it turns out that the usb cable is a 5 (not 4) wire
cable. If you ground the 5th wire, it turns the usb port into a TTL
level serial port. Combining this with a level converter and a baud
rate converter should let the 31x talk to 4800 baud devices (assuming
you don't overrun the buffer in the baud rate converter). And then
there is the issue of the software on the 31x making assumptions about
what baud rates various devices (SN10, CAI 10/20/25 etc) can
communicate at.

Working on the problem with all the necessary parts. Standby.

Good work Nick. I await with bated breath! Can you magic up some charge
current at the same time??
