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

[Arcona 32]

Hi Louise, thanks for your reply, please see my comments below by your questions!

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? -Its an icon with a red cross (see attached picture)

Where are you seeing the message 'no antenna'? Could it be 'lost fix' or something similar you are seeing? - Its also on the attached picture in the upper left, in Swedish "Ingen Antenn". Fix is OK

Your ships GPS will not be the GPS source for the AIS unit, the AIS unit will have its own independent GPS antenna. - Yes, it has a separate 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? - No; just one C120. I can see the satellite status of the AIS if I connect a lap top to it. Sorry for the confusion

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? - yes, please see picture. I think that the pilot was not turned on and I have no radar

When the alarms go off, do you see the messages on both of the C120s? - Just one C120

How are the products networked? Can you send in a system diagram? - I have just bought the boat so I have no real diagram. However I have detected fluctuating 3V on the NMEA connector (on the cable side) when not connected to the C120. I have barked the corresponding on the picture

It seems to me that the C120 cant read the input?
