Hi all!
I’ve been having an issue lately — it’s the third time today — related to the log. Exp is working fine, all data is being received from the instruments and the other connections, but when I review the log it’s incomplete. For some reason, Exp stopped logging in the middle of the race. There’s no visible onboard network problem, laylines working all the races......., etc.
Is anyone else experiencing this issue?

Have you looked in Expedition's System/ error logs?
Exp may log an error if it can't open the file.

No files at error folder......
Main changes to EXP and n2k net:
-Increased logging freq to 2Hz
-Added a second ACT NGT1 ( different source node) to n2knet to receive AIS data and GPS data direct to exp.

At least for now…From my point of view, after uninstalling the second NGT1 (which was used for GPS, AIS, and sending waypoints to the autopilot), all the “fast packet” errors on the network disappeared. When both units were installed, some sensors didn’t work properly (Cyclops gateway, YD engine data, etc.), with small micro‑freezes here and there. I imagine exp must have been quite frustrated........The primary NGT1 is the one used to connect the Processor to the N2K network.
