[TG] [TG11] A98 does not recognize AIS

[Tom - Raymarine - Moderator]

Hello Bob,

The a98 is showing Silent Mode for AIS status because it's not getting information from the AIS that the AIS is transmitting your position data. That's not to say that the AIS isn't transmitting, only that the a98 doesn't know that it is, and I suspect that this is because it's a non-Raymarine AIS. I don't know the exact format of the information that the AIS uses to tell the a98 that it's transmitting, but I'm reasonably sure that it will be a proprietary message that the Sitex AIS won't be sending. You can therefore ignore this status field on the a98.

Re. the NMEA output from the AIS, I would leave all of those messages disabled. The only messages you need from the AIS will be AIVDO and AIVDM (the AIS data itself.) I doubt, as I say, that the AIS's GPS as is good as the a98's and having the AIS output GPS is therefore likely to be counter-productive.

Regards,
Tom
