[LW] [LW11] C120 does not communicate w AIS CTRX GRAPHENE

[Louise - Raymarine - Moderator]

Dear Arcona 32,

Thank you for your post.

When you refer to having 'no AIS' , is this a text alert you see on the screen or the AIS icon in the homescreen has a red cross through it?

Where are you seeing the message 'no antenna'? Could it be 'lost fix' or something similar you are seeing?

Your ships GPS will not be the GPS source for the AIS unit, the AIS unit will have its own independent GPS antenna.

To confirm your issue - you have 2 C120 displays on your boat. One is showing AIS targets in the chart screen and the other unit is not? Is that correct?

On the top right hand corner of the screen there is a blue box with 4 icons showing AIS, GPS, Pilot, Radar and the vessel. Have any got a red cross through them?

When the alarms go off, do you see the messages on both of the C120s?

How are the products networked? Can you send in a system diagram?

Many Thanks
Louise
