View Full Version : Cambridge 302A/303/SNav question

Hi,
Has anyone ever tried connecting a Cambridge 302A (FR) to a Cambridge
303 display and then use the same GPS source to drive an SNav?
Even though you wouldn't get final glide aound a turnpoint in the Snav
is the 302A able to support a GPS signal to the 303 as well as the
SNav?
Thanks for any info.

Hi Bob,
The 302A can be connected to the 303 and also send GPS data to another
device. Two different data connectors are used.
However, you are much better off connecting a GPS-NAV to an S-NAV because
the GPS-NAV can send destination elevation to the S-NAV while the 302A does
not.
Also, the 303 works great with the 302A for navigation, but the 303 cannot
display final glide information like it can when connected to a 302.
Good Soaring,

What if you sent same (302A) to an L-NAV ?

Hi,
The same is true of an L-NAV - it prefers data from a GPS-NAV to data from a
302A or any other GPS. The latest versions of L-NAV and S-NAV firmware
worked the same with GPS-NAVs and PDAs.
It would be great if a 302A sent the same data as a GPS-NAV, and acted as a
data bridge like a GPS-NAV does (sending L-NAV or S-NAV data to a PDA and
allowing MacCready exchange between the PDA and L-NAV or S-NAV) but it
doesn't.
However, there are many advantages to the 302A when used with a PDA. It can
provide a lot more current for the 5A PDA power output so it can power the
latest iPAQs (the GPS-NAV can't). It also meets more recent IGC
requirements so it can be used for World records and it provides the flight
log as an IGC file rather than a CAI file. Also, it holds 1500 waypoints
compared to the GPS-NAV's 250 and it holds 100 hours of flight log compared
to 10 or so for the GPS-NAV.

VERY IMPORTANT!
GPS-NAV's must be upgraded to a version higher than v5.1
before they can be connected to a PDA

Have Cambridge Model 20, upgraded GPS-NAV and L-NAV,
not trying for World Records, but badges and competition -
what suggestions for PDA and software?

Back in the twentieh century...for our winter solstice
question we could bat around the value of 2-33's.
The twenty-first century has introduced this question
as our way to pass the winter...hardware and software
combinations, plus cable and software analysis programs.
A PhD dissertation would be possible on this subject
I think :)
Would you like free, low-price or high price? Likewise
do you prefer more complex over more simple?
I prefer cheap and simple...so I have a SNAV/GPSNAV,
Compaq Aero 1530 and GNII. The Aero has long been
out of production, occasionally they pop up on eBay.
I purchased a second one as a backup. I will live
the B+W screen vs color to others to analyze.
A soaring friend of mine made a sage comment when comparing
systems...'Even if identical systems, no two pilots
have them set up the same...so one is always comparing
apples to oranges'.
Paul Remde's site is invaluable for looking over combinations
and deciphering information.

Thanks Paul
I now have the 302A feeding a 303 and an S-Nav which works out well for
me.
I know I haven't got all the features that a GPS-NAV would provide but
the ease of use and features of the 302A far outweighs these other
functions.
