As Kev says the EW will log without the Oudie, connecting the two together
allows the Oudie to get a better GPS signal and also to get a barometric
altitude from the EW (if you use and Oudie on it's own it uses GPS
altitdude).

The Oudie also has it's own internal GPS & is fairly happy to work
without
connection to the EW. The non-IGC Oudie logger trace can't be used fo
badge claims, world records, depends on the scorer for comps.

So the pair will work fairly happily without any form of connection.

However some of the early Oudies has issues with "smoothing" of the GP
position data (The hardware was originally intended as an automotiv
SatNav) so the Oudie will work "better" if it gets GPS data from the EW
And at least then what you see on the Oudie will be what get recorded in
the EW so no shance of thinking that you've reached a TP only to find
that
your claim gets rejected.The other advantage of connecting the two is
that
you should be able to declare your task from the Oudie to the EW.
