We have tested the new wiring for seatalk1 on the current MacArthur HAT v1.0 and it works like a charm connected to an old Raymarine E80. The first difference you will see is that the SEATALK1 LED is no longer fixed, it will blink when data is received.
This is what we are asking beta testers to try. The first image is when it is not powered from the seatalk1 bus and the second is when it is. You need to check Invert signal in OpenPlotter GPIO configuration.
Publish here your results please, thanks!!!
