Classic E80 Chartplotter

[Ian_Rob]

Why would my Raymarine Classic E80 be reporting the date as 11/02/2004? The time is correct.

The GPS clock rolls over something like every 19 years. Some older GPS receivers did not know how to handle this.

Thanks, Can it be corrected?

Yes. With a Raymarine 130 or 150 gps.

Any nmea gps receiver would connect to the c80 nmea input. You will have to disconnect the old gps receiver as on the c80, any gps data on the seatalk bus takes precedence.
If you have an ais transponder connected to the c80 you may find it is possible to configure the ais transponder to pass its gps data to the c80 together with its ais data (which is what I did). The C80 seems to then pass the gps data across to the seatalk bus ok.

Thank you. Currently my AIS is connected to a standalone Axiom rather than to my E80 but assuming the connectors are compatible I can at least try the AIS GPS Antenna and see if that solves the date problem.

As an aside, I seem to recall that AIS and chartplotters must have separate GPS antennae but that may no longer be the case??

Don't fiddle with the AIS GPS antenna. Most AIS have NMEA outputs which can connect to one of the C80 NMEA inputs.

Ais transceivers must have its own dedicated ais antenna. These are usually just antennae and not gps receivers - that functionality is provided by the transceiver itself. You will need to connect the nmea 38400 from the ais unit to the C80 and just disconnect the existing raystar 150 from its power source. Remember to reconfigure the C80 nmea to ais speed!

 

[DipperToo]

If the C80 does not pick up gps position after this change, it may well be that the transceiver needs a setting changed. What transceiver do you have fitted?
Also, as i found out after a factory reset, you must also check that the ais layer is active on your C80.

Does it matter that the OP specified an E80 not C80?

Not in this case.

Most AIS have 2 NMEA ports, normally set as default to 9600 and 38400. I'd use the default settings, with AIS needing 38400, leaving 9600 for GPS.
