Thanks everyone. I'm using theCAIUtility v. 2.5.6 with a Belkin USB
to serial adaptor. I think the302logging interval is 4 sec (but will
check tomorrow). Bill- Hide quoted text -

I checked & the logging interval is set at 4 sec. I also tried another
Belkin USB to serial adaptor, but thedownloadrate was the same. I
then tried todownloada flight log from a302in another a/c, but
again thedownloadrate was veryslow. Any further suggestions?

I would try downloading to a PC with a REAL serial port, or to a PDA and
so remove the Belkin from the equation.

I had this problem once. *I can't remember if I was using a Belkin brand
USB-serial, but I was using a "name brand" one (i.e. not the cheapest
no-name brand that I could find). *It may very well have been Belkin.

The first time I tried it, it was amazinglyslow(like an hour todownload
a flight). *After some dead-scratching, I went out and bought another
(cheap) USB-Serial (I believe the brand is "Prolific") and it's been
working fine ever since.

I have no explanation for this, but I'd suggest spending $10 to give
another brand of USB-serial. *My suggestion would be to try to find one
that has a driver packaged with the unit. *I have a theory that some of
the units that don't have their own drivers utilize "generic" drivers, or
else they use an inappropriate driver and this can cause weird problems..
I may be wrong about the driver issue, but buying a cheap Chinese-brand
USB-serial that came with its own driver disk worked for me.

As suggested I tried downloading with a PDA. Resurrected an Ipaq 2490,
loaded the CAI utility program & borrowed a cable. The download of the
4.5Hr flight that had taken 1Hr 10' with the Belkin serial to USB
adaptor, took less than 3' with the Ipaq. Thanks again for
suggestions. *Bill

I don't know much about 302. But I use it for 10 years and one thing
I've noticed is that it doesn't like to download anything, when the
main battery is low. It that is a usually the case after a long
flight.
