Weather sensor with display crashing in OpenCPN

[patrickza]

Hi everyone. I bought the wind sensor with display from the pypilot store and a Davis anemometer. It works fine just on the display, but when I add it to OpenCPN it seems to crash and reboot.

Here's a video showing what I mean: https://youtu.be/sGNY9OGX1i8

As you can see it runs perfectly fine on a PC until I try configure it to open CPN where it seems to be in a reboot loop. Here's the debug data I pulled from OpenCPN:

Then I tried reading that serial port in putty and it ran perfectly, no reboots or any other issues. Here's some data from putty:

Anyone have any idea what's going on? I have tried two USB cables, same behaviour on both.

Thanks

Edit: Also works fine in NavMonPc.
