Ivanm..
Yes RS422 would work.
Pins to use are 2,(3) and 5. (3 for out to for example a Auto Pilot)

Re: Help / FAQ

Hi,


I am having trouble getting the mouse-wheel zoom to work correctly on openCPN. When I hover the cursor over a point and zoom in, it does not zoom in to that point. This makes route planning exceptionally difficult: you zoom in to an area of interest, create a few waypoints, eventually getting to the edge of the screen, zoom out with the wheel, place cursor over the next area of interest .. zoom in and it does not zoom to where you want it to. Try dragging the map and it places a new way point.


This behaviour is counter intuitive and significantly different from most other commercial software, across many fields. How do I configure OpenCPN to zoom to the cursor?

Re: Help / FAQ

You go to the Toolbox and enable "Zoom to Cursor" on the Display->General tab (The first one you see)

Ah yes, right in front of my eyes! I was looking in the "User Interface" section rather than the display section. Perhaps moving it (or duplicating it?) might make sense as it is more of a UI thing than a display thing?


Either way, thats much better, thanks!
