Default L-Nav question

Hi Greg,

Since you can't enter tasks or select an active waypoint in the PowerFLARM,
it can't send the distance to the active waypoint to the L-NAV. *Also, it
sends data at 19200 baud while the L-NAV needs 4800 baud.

The GPS-NAV is really the best thing to connect to an L-NAV. *It is the only
device that sends airport elevations to the L-NAV.

Best Regards,

Does a newer logger (such as the one in the PowerFlarm) work OK with an
L-Nav, or is there a reason for an L-Nav owner to keep the old model 20
logger?




Just one point -- before the 4800 baud comment scares a bunch of
people. Existing Flarm products support 4800 baud NMEA output and I
see no reason that the PowerFLARM would not - it is an obvious need,
its the industry standard/default NMEA baud rate, and would break lots
of things if it didn't. Its easy to configure Flarm Baud rates (e.g
with the Flarm tool). The default rate on Flarm products has been
19200 baud and I assume the PowerFLARM will be the same, if you change
it to 4800 baud the device cannot put the Flarm traffic data into the
NMEA stream (4800 baud is too slow to do this) but then if you have a
device that can only work at 4800 baud it is not going to know what to
do with the Flarm NMEA traffic data anyhow.

I'll confirm this after I steal a PowerFLARM from Urs on Saturday :-)
