Thanks again to those that posted replies to my issue with the E120 Classic reboot issue. Here is an update on it, in case anyone else has the same issue.
Raymarine Tech support looked at the wiring
diagram of what was connected to the chart plotter. The only change they suggested was to power the Seatalk
HS bus from a separate 12Volt supply, not from the 12volt output of the old Sea talk bus. This change was made.
We set sail from Pasadena Maryland
on the Chesapeake Bay
to Port Hawkesbury Nova Scotia
. About 1/2 and hour after leaving Pasadena ( Close to Baltimore
harbour ) the chart plotter did its beeping and reboot sequence. Oh sh@#t this is going to be a long stressful trip.
However I it was not. The chart plotter was stable and worked like a charm all the way to Nova Scotia
and back down the USA coast until we were approaching Newport
Road Island, and then it started having a hissy fit again. Beeping and rebooting regularly. This continued until we left Newport
. All was stable until we got closer to New York
coming down Long Island sound
. Same problem.
Side Note! Had a fantastic sail down the East river with Genoa
only. Rolled up the Genoa
just before Hell Gate, 3-4 knot current
- yee haa what a ride past Manhattan Island. Anchored overnight for free and with a view of the Statue of Liberty less than 1/2 a mile away. Does it get any better than this?
As soon as we left the New York
area, the chart plotter was stable again, all the way back to Pasadena arriving at 3:00am (Note! not much AIS
traffic at this time of night. )
Went out for a sail this long weekend. ( Note, lots of sailors out) and within 1/2 and hour the chart plotter goes into its routine.
OK, it looks like the issue is related to the amount of AIS traffic about. To stop the AIS data getting into the Chart plotter I changed the baud rate setting for the AIS interface. The chart plotter was stable for the next 3 hours until I changed the baud rate back to check out where a large cargo ship coming out of Baltimore
was headed. Within in 10 minutes the chart plotter did its frustrating beeping and reboot sequence.
To me this issue seems very much related to the amount of AIS traffic. If it is too much the chart plotter gets very slow in it responses to button presses, the amount of disk usage ( solid state I imagine) gets up to 99%
and reboot here we come. We did monitor
the disc space usage, and I have seen it reboot at levels around 95%.
Anyway, I have contacted Raymarine tech support with this new diagnostic info and await a response.
Hopefully I have made some silly configuration mistake in the software
that when corrected will fix this issue. But in the mean time if I want to have my chart plotter and RADAR up and running in a busy AIS area, I have a workaround which is to stop the AIS data getting to the chart plotter by changing the Baud rate.
We had a fantastic trip to Nova Scotia. Went through our fist lock and got onto the Bras d'Or Lakes. Beautiful area. Fantastic weather this time of year ( August), VERY VERY friendly and welcoming people. I would encourage any sailor to go there if you have a change.
