My Autopilot display/control instrument is reporting STLK FAIL. This is a Seatalk Failure. This means that the Seatalk data is not correct or not present.
I have three Raymarine instruments at the binnacle. An Autopilot ST6000+, a Wind ST60, and a Tridata ST60. As well as being connected to the wires from the wind transducer, speed transducer, and depth transducer, they are linked by Seatalk cables. I have attached an “engineering schematic” of the wiring at the back of the instruments.
As you can see from the schematic, the Seatalk cables run from the Course Computer (located in the saloon) to the Autopilot, then to the Wind, then to the Tridata.
I have done some experimentation by changing/moving the Seatalk cables. The symptoms in the various configurations are:
1. Normal configuration: Wind and Tridata operate as normal, Autopilot displays STLK FAIL
2. Seatalk plug P1 removed from Autopilot input S1: All instruments are OFF (as there is no power to any of them)
3. P1 plugged back into S1, and P6 removed from S6 on the Wind: Autopilot now works ok but Wind and Tridata are OFF (no power to these two)
4. P6 plugged back into S6, and P5 removed from S5: Autopilot works ok, Wind works ok, Tridata OFF (no power to it)
5. P5 plugged back in to S5 on the Wind, P3 removed from S3 on the Tridata: Autopilot works ok, Wind works ok, Tridata OFF (no power to it) – same as 4 above
6. P3 left unplugged from S3, P6 removed from S6 and plugged into S4 on Tridata: Tridata works ok, Wind OFF (no power to it), and Autopilot displays STLK FAIL
Does this suggest my Tridata instrument is faulty, as when this is connected as part of the Seatalk "cable run" the Autopilot displays STLK FAIL?
If I need to replace the Tridata, what should I replace it with? Is an I60 a drop-in replacement? Or is a second hand ST60 a better option?
