Raymarine forum

I have an e127 MFD and I am trying to specify the data sources. When I do, it diplays an error:

Data selection not possible
The following devices are preventing data source selection
ISO(77 9a 6e e7 00 8c 8c c0) CAN(43)

I have determined that CAN(43) is the AIS650.

Any idea what the problem is?

jeokeefe,

Please click here to view a FAQ addressing this subject. Please additionally note that the AIS650 transceivers may also block source selection. Temporarily disconnecting the AIS650 from the backbone will then permit the Data Sources feature to be used. Following Data Source selection, the AIS650 may be re-connected to backbone.
