In my setup the st5000+ did not work.
The 4000 series buffer i connected between the seatalk bus and mcs bord has a very high input impedance and does not load the seatalk bus. This worked!
I have not looked at the signals with a scope but my solution to the problem implies that the mcs board can load a seatalk bus to much. Thus higher input impedance than the mcs optocoupler circuitĀ needed.
