Hi all,
I have a NASA clipper wind transducer and I'm trying to connect this to signalk via a RS422/RS485 USB serial adapter. Being new to all of this, I don't know where to map wires from the transducer to the serial adapter.
Based on the attached diagrams (first is from the transducer manual, the second from https://open-boat-projects.org/en/category/projects/) I would assume:
Transducer -> serial adapater
Black -> GND
Blue -> +RXD
This may be obvious but the USB serial adapeter has the following terminals:
T/R+
T/R-
RXD+
RXD-
GND
When I connect it all up, the RXD light flashes a few times and stops so I'm assuming this isn't wired up correctly.
