E80 Classic

[Ian_Rob]

Had our last sail of the season the day before yesterday before putting the boat to bed for the winter. I noticed that the date and year on the E80 and the Icom 505 was showing as March 28th 2005. I am under the impression that this issue relates to GPS antenna which is the original one and 16 years old. Will a new Raymarine 150 antenna sort the problem……?

Ian,
I had the same issue with my C80 classic. I was confused since there is a correct date stamp feed from my Emtrac AIS transponder (B100), feed via NMEA. I think it may be a date rollover issue, I read on this forum at the weekend that the plotter prioritises the raymarine GPS feed, and once I disconnected the seatalk yellow wire (data) all was well. This does mean that I will be using the Emtrac GPS for navigation and not the Raymarine one on the.pushpit, so I will monitor the situation. Perhaps I can remove that aerial if all is well. But this fix only works if you have another GPS serial data input.

Thanks. I also suspect that it is a rollover problem. I also have an Emtrak GPS antenna and can perhaps use it to test whether a newer antenna will resolve the problem…..

The Emtak has NMEA 0183 out, so just connect that to the E80 and disconnect the Raymarine one, job done.

On second thoughts, doesn't the Emtrak already connect to the E80 for AIS ? If so, connect a laptop to the Emtrak and using ProAIS2, on the configuration tab, turm on GLL and GGAand write the configuration back to the Emtrak.

I had that. I believe the C80 defaults to GPS if available on the Seatalk bus. I disconnected the old Raymarine GPS and made sure that my AIS transponder was set up to broadcast its GPS data along with the AIS stream. Problem solved!

Good to hear that there is probably an easy solution. Thanks for the replies.

If my memory serves me well, You just need to replace the button battery in the GPA attenna

Not in this case.
