The original documentation says that in this scenario the ST GND jumper should be set to open. This is incorrect, it needs to be set to closed.
Looking at the V1.1 schematic, it looks like the jumper has been removed. Will the data connector still work as a bilge alarm?
Also, I like how the connector is labelled "Data", since it has lots of potential uses (digital in, digital out, pulse or SeaTalk). But the LED is labelled "SEATALK1", could it be renamed to "DATA" instead?
The 12V SW input behavior has changed in v1.1. Now it needs to be closed to keep the system powered. This could be a possible use for a similar purpose using its own sensor instead of the bilge pump:
Good point. We should see how the seatalk circuit finally works and the possible alternative uses to chose the label.
Interesting, so for a digital input we'll need to earth the data connector instead of powering it. How would this work for a pulse input or a digital output?
