LXNAV V3 looks like an interesting device. It seems to have RS232
communication - what data does it send out? Can flight computer
application like XCSoar communicate with it?

Kimmo,

The V3 serial interface is used only for firmware update. It cannot output to navigation software, for that you need the V7.

Happy New Year

The V3/V7 price difference is interesting. It must be mainly justified by marketing rather than the different electronics?

Hi,

There is a big hardware difference between the V7 and V3. The V7 has pitot
an static inputs and can therefore display push/pull (speed-up/slow-down)
commands. The V3 does not have pitot or static inputs. It can tell you how
fast to fly, but it doesn't know how fast you are flying, so it can't tell
you to speed-up/slow-down. The V3 is a great new idea. It is a Total
Energy vario with audio, with the ability to display the recommended
speed-to-fly based on your glider's polar and the current MacCready setting
and the current lift/sink. It is a lot like having a smart MacCready ring
on a mechanical vario. You can see details here:

Can the mechanical needle of the V3 function without electrical input? So, if a total power loss, any vario function left? Thanks,

Hi,

No. The needs is driven by an electrical stepper-motor, so it won't work if
there is no power. However, the V3 can be powered by an small backup
battery or battery pack. It operates on as little as 6V. A battery pack
from Radio Shack that holds 4 to 6 AA batteries would work great as a
backup. A panel mounted switch could be used to switch to the backup
battery pack if the main battery gets too low. Or, you could use 2 main
batteries and switch between them as necessary - that is very commonly done.
