[DG] [DG11]Seatalk Failure

[Derek - Raymarine - Moderator]

Hi,

It is possible that one of the two SeaTalk connections on the control head is faulty, maybe a damaged solder joint inside the display? the two SeaTalk connections on the displays are simply in Parallel, so that is all that can be the issue.

One more test - disconnect the control head from the computer completely, connect the two other ST60 displays, then turn the lights on on one of the displays, the lights on the other one should come on - if they do, it confirms both they and the computer are fine and communicating via Seatalk, if they don't, the isolate the two displays, so it is just the two of them connected together and powered, repeat the lights test, if the lights come on together, then the issue is within the course computer.
