I have been trying to connect my old Garmin Plotter to my pi via NMEA0183-RS422-USB. the RS422-USB device is:
https://www.amazon.com/gp/product/B076WVFXN8
at first it had me scratching my head because TX+ to RX+ and TX- to RX- did not work but connecting TX+ to RX- and TX- to RX+ worked, and so I also connected RX- to TX+ and now I have lights - Red for Power, Amber for RX and then after selecting "depth under transducer" in the signalk to NMEA0183 plugin - Green for TX - and I got a notification on the Garmin that the depth was shallow (I am out of the water!)
what I am not seeing is any data in Signalk. I played around a little with the options:
but could not see any entries in Signalk
Any ideas?
