The new AIS 650 unit that was sent back to Raymarine did have an older version of the firmware installed. It was upgraded to the latest version and sent back to me. I installed and still have the same problem.
I finally got to speak to one of the second level support technicians at Raymarine regarding this issue. This post will be much shorter than my previous posts on this issue.
This issue was a known bug and was meant to be fixed in version 5.69 of the E120 firmware.
It appears that this fix did not make it into the final build of the firmware, or the implemented fix did not fix the issue.
Because the E120 Classic is obsolete there will be no further releases for the E120 classic.
I have the following options.
1. Put up with the reboot and very slow operation in high AIS traffic areas. About 30-50 targets will make it reboot.
2. Change the baud rate as I have been doing to stop the AIS traffic into the E120. This leaves the E120 operating for chart plotter, RADAR
etc, but no AIS.
Well that is most of the bad news for the day, the remaining bad news is that because I put in a new thru hull
Raymarine Downvision Sonar transducer on my last haul out
and if I want to use this transducer I have to remain with Raymarine as my chart plotter.
I have been assured that the new E125 series will not have this problem as they have much more memory and processing power.
I hope so. I not hopefully they can fix the bug before the new E125 becomes obsolete.
They are offering a $500 rebate at present, so maybe a new model is coming and this will happen sooner that we expect.
Regards to all.
