[CA] [CA11] NO DRIVER DETECTED

[Chuck - Raymarine - Moderator]

ag,

The reported symptom may occur if the EV-1 and ACU have incompatible software versions. Accordingly, it would be recommended that the ACU be temporarily disconnected from the backbone and then the EV-1 be updated with the latest available Raymarine product software update. After doing so, the EV-1 should be disconnected from the backbone, the ACU should be reconnected to the backbone, and then the ACU should be updated with the latest available Raymarine product software update. After doing so, the EV-1 may be reconnected to the backbone and the actions specified within the FAQ found here should be followed.
