[CA] [CA11] Problems with Fishfinder

[MojMoj]

Hi. I have a Raymarine/Airmar P66 connected to a Raymarine DSM 30 connected to a Raymarine C120.

The Fishfinder/Transducer works fine about 75% of the time, but a couple times every hour it will ether (i) shift over to a different model of transducer (more frequent) or (ii) stop providing information.

When it shifts over to a different model of transducer, the P66 is no longer selectable from the menu. When this happens, usually the sonar continues to work and just the speed disappears. Usually I go to "reset DSM" and it will clear up the issue. Sometimes I have to try more than once but it usually clears up quickly.

When it stops working completely, I lose all sonar information. The model correctly identifies, and the diagnostics show packets being sent and received but no sonar data comes through. usually I have to reset many times over a longer period of time (e.g., an hour) to get it working again. This type of error is infrequent.

Would appreciate any advice to help diagnose the above.

Thanks,
